Buy The Dips in Bull Market (by Coinrule)During a Bull market, beating the market, it's challenging. Trading strategies that buy the dips represent one of the best approaches to surf the trend and optimize the returns.
The main obstacle is to gauge the dip's magnitude properly and set up the take profit level accordingly. The RSI is an excellent tool to catch price drops as it adjusts the entry to the asset's current volatility. Nevertheless, using the RSI as an indicator for exit is not an optimal solution in trending markets as it may end up with two scenarios:
The price reverts before reaching overbought conditions. That is the case when the trend is not that strong at that moment. Leaving the position open could result in missed profit opportunities.
The price rebounds strongly, leading the RSI quickly in overbought conditions too soon so that the strategy sells too early.
One interesting option is to combine a trigger based on the RSI to catch the dip and then use two moving averages to spot the right time to seel when the price is entirely back on-trend.
The Setup
The entry-signal comes when the RSI is lower than 35 and the MA9 is above the MA200, indicating that the asset is currently in an uptrend.
The sell-signal comes when at the same time, the price is above the MA9, and the MA9 is above the MA50.
This setup was optimized on the 15-min time frame after over 150 backtests.

TrendLine ChannelsAbstract
This script provides a set of Trendline Channels which can be tighter than Donchian Channels.
This script computes the most suitable active upper and lower trendlines and updates them as soon as possible.
We can use it for breakout signals earlier than Donchian Channels.
Introduction
Channels are tools which can mark area of values of ranging markets.
Once the price leaves the original region, range traders may start admitting they are wrong and trigger trend.
Donchian Channels (misheard as Dungeon Channels) use the highest and the lowest price to define area of values.
When the price breakouts, it just like it got released from a dungeon.
However, waiting for the price making even higher or lower may be too late and risk reward ratio may be lower.
Trendlines can make the channels tighter and we can find earlier breakout signals.
Computing Trendline Channels
(1) Find the most active trendlines
In this script, a valid trendline connects two high values or two low values.
A high value means the highest value in a trading day.
A low value means the lowest value in a trading day.
In this script, every trendline does not crossover any bar but can exactly touch them.
The most flat trendline is taken. (one for upper and one for lower)
(2) Continue to use or Change a trendline
If there is a tighter trendline available, this script changes to use it.
If the previous active trendline is broken, this script re-computes the trendline available.
When this case happens, this script display with an another color.
Otherwise, this script continues using the previous trendline.
(3) Middle line
The middle line indicates the middle value between the upper and the lower.
Parameters
Length : how many days are used for computation. The default value is 16 just because 16=4*4, using binary characteristic.
x_go_on : If the previous trendline is not breakout and there are no tighter trendlines available, we continue use it.
Color Options
(1) Upper trendline (no update or tighter)
(2) Upper trendline (changed due to breakout)
(3) Middle line
(4) Lower trendline (no update or tighter)
(5) Lower trendline (changed due to breakout)
Conclusion
Trendline Channels can be tighter than Donchian Channels and evaluate earlier breakout signals.
Comparing to known auto trendline scripts, Trendline Channels is continuous.
Once a trendline is broken, Trendline Channels can instantly point out the next available one.
If you think the price movement is boring or you cannot have good risk reward ratio, you can go to an another timeframe.

RSI of VWAP [SHORT selling]This is SHORT selling version of RSIofVWAP strategy. Settings and Logic are totally different from LONG side version , hence I am publishing it as a new strategy.
Settings
============
VWAP of RSI Length 15
Slow EMA Length 200
Short entry level 25
Cover short level 70
stop loss 5
SHORT Entry
============
condition1 : When RSIofVWAP crossdown below 25 and VWAP is below ema200
condition2: When weekly RSIofVWAP crossdown 70 and VWAP (note : session vwap , not weekly vwap) is below ema200
condition3: Use VIX value , if you want to short when the price is above ema200
vwap RSI crossing down 70 and VIX RSI is cossing up 70
enter short ... This is like falling knife :-)
I need to add the code -- later
if any of above condition is TRUE , SHORT entry will be taken
Take Profit
============
When close less than short entry price and RSIofVWAp is crossing up 25 , take profit ...close 1/3 of the position
Exit
============
When RSIofVWAP crossing up 70 level
Stop Loss
============
Stop Loss is set to 5%
Note:
1. When strategy is in SHORT position , background and bar color changes to gray
2. When strategy is already in short position , possible entries are shown in yellow background
3. RSI Length 15 is working most of the equities on hourly chart. ( RSI length 9 and 14 also works good , but not for all ... You may want to try which setting works for your symbol)
4. weekly VWAP (blue color) is also plotted by default ... you can disable it if you dont want to see it. But there is advantage keeping it on the chart , you can notice whenever weekly VWAP crosses above 70 line , trend is UP ... if you have LONG position you can hold on it ... Hurray :-)

MACD Strategy with trailing ATR stopThis is a trend based strategy that uses EMA and SMA intersection for determining the direction of the trend and MACD for the entry signal. At the same time, the strategy uses ATR, which is working as a trailing stop.
The strategy entry will work when the Trend ribbon will turn green and MACD line will crossover the signal line. This strategy also takes into account the pyramiding and allows to enter the second time if the signal will repeat itself.
There are 3 exit points. The first 10% of the position will be closed when the price will increase by 1%. The second portion of 50% will be closed when the price reaches 5% Take profit target. The remaining 40 % of the position will wait for the exit signal which will occur when the price closes below the ATR line.
The strategy is using a fixed amount in dollars, each time the entry occurs the strategy will enter with 100$ in the order.
The strategy can be applied to other crypto assets. However, they will require input changes.
Best of luck with your trading.
Multi MA MTF SandBox StrategyA moving averages SandBox strategy where you can experiment using two different moving averages (like KAMA, ALMA, HMA, JMA, VAMA and more) on different time frames to generate BUY and SELL signals, when they cross.
Great sandbox for experimenting with different moving averages and different time frames.
== How to use ==
We select two types of moving averages on two different time frames (or the same time frame):
First is the FAST moving average that should be at the same time frame or higher.
Second is the SLOW moving average that should be on the same time frame or higher.
== Buy and Sell Signals ==
When FAST moving average cross over the SLOW moving average we have a BUY signal (for LONG)
When FAST moving average cross under the SLOW moving average we have a SELL signal (for SHORT)
WARNING: Using a lower time frame than your chart time frame will result in unrealistic results in your backtesting and bar replay.
== NOTES ==
You can select BOTH, LONG, SHORT or NONE in the strategy settings.
You can also enable Stop Loss and Take Profit.
More sandboxes to come, Follow to get notified.
Like if you like and Enjoy!
Can also act as indicator by setting 'What trades should be taken' to 'NONE':
Socrates Reversals PlotterSOCRATES Reversals Plotter
Introduction
This script is intended for users of the Socrates platform. This is located on ask-socrates.com which is property of AE Global Solutions, Inc.
Background
It is cumbersome to track the reversal system on the proprietary platform especially when users want to combine it with real-time data on TradingView. Some active reversals, especially those on the daily level change quite often and updating the charts regularly takes a lot of time. Therefore I've created this script primarily for the following reasons:
Simplify the process of keeping the charts updated
Standardize the look of the graphs so that they can be quickly understood when shared with other users for studying purposes and discussions
Features
v1.0 (20201203)
Add up to 5 daily/weekly/monthly reversals which will plot and format automatically
Easily hide daily/weekly/monthly reversals as a group
Highlight the range of a given unit of reversals. This takes the values of the lowest bullish and highest bearish reversals. They are expected to be written in #01 fields
Don't forget to use the option to "Save As Default" at the bottom of the Inputs tab. This will make sure all your reversals are stored even if you remove the indicator from your graph
Trend-following RSI Strategy According to classical technical analysis, an RSI above 70 should signal overbought conditions and, thus, a sell-signal. Cryptocurrencies represent a whole new asset class, and they reshape the classical concepts of technical analysis. FOMO-buying can be very powerful, and coins can remain in overbought conditions enough to provide excellent opportunities for scalping trades on the upside.
Building a trend-following trading strategy based on the RSI, which is generally considered a contrarian indicator, may sound counter-intuitive. Over 200 backtests prove that this is a very interesting long-term setup.
The setup is optimized on a 4-hours time frame and trading cryptocurrencies versus USD or stable coins.
The strategy tries to catch coins on sustained uptrends to take advantage of further upside.
The strategy's buy-signal triggers when a coin has an RSI above 70 on a 4-hours time frame.
The strategy sells the coin if a profit of 6% is achieved. Alternatively, it closes the position if the RSI drops below 55, indicating a possible weakening of the trend.
The strategy assumes each order to trade 30% of the available capital. A trading fee of 0.1% is taken into account. The fee is aligned to the base fee applied on Binance, which is the largest cryptocurrency exchange.
[blackcat] L2 Ehlers DFT-Adapted RSILevel: 2
Background
John F. Ehlers introuced his DFT-ADAPTED RELATIVE STRENGTH INDEX (RSI) in Jan, 2007.
Function
In "Fourier Transform For Traders" in Jan, 2007, John Ehlers presented an interesting technique of improving the resolution of spectral analysis that could be used to effectively measure market cycles. Better resolution is obtained by a surprisingly simple modification of the discrete Fourier transform. John Ehlers suggests using the discrete Fourier transform (DFT) to tune indicators. Here, I demonstrate this by building a DFT-adapted relative strength index (RSI) strategy.
Rather than display the RSI for a single cycle length across the entire chart, Ehlers DFT adaptive RSI value reflects the DFT-calculated dominant cycle length RSI. If the dominant cycle changes from 14 to 18 bars, the RSI length parameter changes accordingly. Computationally, this requires the strategy to continuously update values for all possible RSI cycle lengths via a "for" loop and array.
In details, a full-featured formula that implements a high-pass filter (HP) and a six-tap low-pass finite impulse response (FIR) filter on input, then does discrete Fourier transform calculations. I has taken liberty of adding extra parameters so the user can modify the analysis window length and the high-pass filter cutoff frequency in real time using the parameters window. Once the suite of possible RSI values is calculated, we use the DFT to select the relevant RSI for the current bar. The strategy then trades according to J. Welles Wilder's original rules for the RSI.

Background
John F. Ehlers introuced the Inverse Fisher Transform of Cyber Cycle in May, 2004.

The transform is applied to any indicator with a known probability distribution function, but this script offers a sample transforms: Cyber Cycle . I have created inputs for the trigger levels for entry and exit so that the user may adjust these levels as desired.
In his article, Dr . Ehlers states the inverse Fisher transform can work with any oscillator, and that values between -1 and 1 are more suited for the transform calculations. Here is one version of the inverse Fisher transform of Cyber Cycle . This version takes the highest and lowest value of the Cyber Cycle and normalizes the scale to a range of -1 to 1. John Ehlers shows how to use the inverse Fisher transform ( IFT ) to compress oscillator-type indicators to give clear trading indications of when to buy or sell. The IFT is a nonlinear transformation that changes the probability distribution, so for example, unbounded indicators can be transformed into bounded indicators with a high probability of being either +1 or -1.

Square Root Moving AverageAbstract
This script computes moving averages which the weighting of the recent quarter takes up about a half weight.
This script also provides their upper bands and lower bands.
You can apply moving average or band strategies with this script.
Introduction
Moving average is a popular indicator which can eliminate market noise and observe trend.
There are several moving average related strategies used by many traders.
The first one is trade when the price is far from moving average.
To measure if the price is far from moving average, traders may need a lower band and an upper band.
Bollinger bands use standard derivation and Keltner channels use average true range.
In up trend, moving average and lower band can be support.
In ranging market, lower band can be support and upper band can be resistance.
In down trend, moving average and upper band can be resistance.
An another group of moving average strategy is comparing short term moving average and long term moving average.
Moving average cross, Awesome oscillators and MACD belong to this group.
The period and weightings of moving averages are also topics.
Period, as known as length, means how many days are computed by moving averages.
Weighting means how much weight the price of a day takes up in moving averages.
For simple moving averages, the weightings of each day are equal.
For most of non-simple moving averages, the weightings of more recent days are higher than the weightings of less recent days.
Many trading courses say the concept of trading strategies is more important than the settings of moving averages.
However, we can observe some characteristics of price movement to design the weightings of moving averages and make them more meaningful.
In this research, we use the observation that when there are no significant events, when the time frame becomes 4 times, the average true range becomes about 2 times.
For example, the average true range in 4-hour chart is about 2 times of the average true range in 1-hour chart; the average true range in 1-hour chart is about 2 times of the average true range in 15-minute chart.
Therefore, the goal of design is making the weighting of the most recent quarter is close to the weighting of the rest recent three quarters.
For example, for the 24-day moving average, the weighting of the most recent 6 days is close to the weighting of the rest 18 days.
Computing the weighting
The formula of moving average is
sum ( price of day n * weighting of day n ) / sum ( weighting of day n )
Day 1 is the most recent day and day k+1 is the day before day k.
For more convenient explanation, we don't expect sum ( weighting of day n ) is equal to 1.
To make the weighting of the most recent quarter is close to the weighting of the rest recent three quarters, we have
sum ( weighting of day 4n ) = 2 * sum ( weighting of day n )
If when weighting of day 1 is 1, we have
sum ( weighting of day n ) = sqrt ( n )
weighting of day n = sqrt ( n ) - sqrt ( n-1 )
weighting of day 2 ≒ 1.414 - 1.000 = 0.414
weighting of day 3 ≒ 1.732 - 1.414 = 0.318
weighting of day 4 ≒ 2.000 - 1.732 = 0.268
If we follow this formula, the weighting of day 1 is too strong and the moving average may be not stable.
To reduce the weighting of day 1 and keep the spirit of the formula, we can add a parameter (we call it as x_1w2b).
The formula becomes
weighting of day n = sqrt ( n+x_1w2b ) - sqrt ( n-1+x_1w2b )
if x_1w2b is 0.25, then we have
weighting of day 1 = sqrt(1.25) - sqrt(0.25) ≒ 1.1 - 0.5 = 0.6
weighting of day 2 = sqrt(2.25) - sqrt(1.25) ≒ 1.5 - 1.1 = 0.4
weighting of day 3 = sqrt(3.25) - sqrt(2.25) ≒ 1.8 - 1.5 = 0.3
weighting of day 4 = sqrt(4.25) - sqrt(3.25) ≒ 2.06 - 1.8 = 0.26
weighting of day 5 = sqrt(5.25) - sqrt(4.25) ≒ 2.3 - 2.06 = 0.24
weighting of day 6 = sqrt(6.25) - sqrt(5.25) ≒ 2.5 - 2.3 = 0.2
weighting of day 7 = sqrt(7.25) - sqrt(6.25) ≒ 2.7 - 2.5 = 0.2
What you see and can adjust in this script
This script plots three moving averages described above.
The short term one is default magenta, 6 days and 1 atr.
The middle term one is default yellow, 24 days and 2 atr.
The long term one is default green, 96 days and 4 atr.
I arrange the short term 6 days to make it close to sma(5).
The other twos are arranged according to 4x length and 2x atr.
There are 9 curves plotted by this script. I made the lower bands and the upper bands less clear than moving averages so it is less possible misrecognizing lower or upper bands as moving averages.
x_src : how to compute the reference price of a day, using 1 to 4 of open, high, low and close.
len : how many days are computed by moving averages
atr : how many days are computed by average true range
multi : the distance from the moving average to the lower band and the distance from the moving average to the lower band are equal to multi * average true range.
x_1w2b : adjust this number to avoid the weighting of day 1 from being too strong.
Conclusion
There are moving averages which the weighting of the most recent quarter is close to the weighting of the rest recent three quarters.
We can apply strategies based on moving averages. Like most of indicators, oversold does not always means it is an opportunity to buy.
If the short term lower band is close to the middle term moving average or the middle term lower band is close to the long term moving average, it may be potential support value.

Multi Time Frame Buy the Dips (by Coinrule)Buying the dips is a relatively easy automated trading strategy that can return impressive profits, especially during uptrend times. Not all price drops are for buying, though. This trading system is based on a multi time frame buy-the-dip approach to optimize each trade.
The strategy catches sudden price drops on a 1-hr time frame when the price increases significantly in the last 12 hours. During steep uptrends, profit-taking price actions result in flash crashes that provide great opportunity to enter at convenient prices.
Buy Condition
The setup of the script is optimized on a 30 min time frame. You can adjust the parameters to fit different time frames.
The system gets a buy signal when
- the price drops 1% from the two previous candles (1 hour time frame = two 30-min candles)
- the price is up 3% from the last 12 hours (twenty-four 30-min candles equal the desired time frame)
Sell Condition
Each trade comes with a stop loss of 3% and a take profit of 4%.
This setup has been optimized, running over 150 backtests on more than 20 different crypto trading pairs.
The strategy assumes each order to trade 30% of the available capital. A trading fee of 0.1% is taken into account. The fee is aligned to the base fee applied on Binance, which is the largest cryptocurrency exchange.
[blackcat] L2 Ehlers Even Better SinwaveLevel: 2
Background
John F. Ehlers introduced Even Better sinwave Indicator in his "Cycle Analytics for Traders" chapter 12 on 2013.
Function
The original Sinewave Indicator was created by seeking the dominant cycle phase angle that had the best correlation between the price data and a theoretical dominant cycle sine wave. The Even Better Sinewave Indicator skips all the cycle measurements completely and relies on a strong normalization of the waveform at the output of a modified roofing filter. The modified roofing filter uses a single-pole high-pass filter to deliberately retain the longer-period trend components. The single-pole high-pass filter basically levels the amplitude of all the cycle components that would otherwise be larger with longer wavelengths due to Spectral Dilation. Therefore, when the waveform is normalized to the power in the waveform over a short period of time, the longer wavelength contributions tend to be an indication to stay in a trade when the market is in a trend.
The Even Better Sinewave Indicator works extraordinarily well when the market is in a trend mode. This means that the spectacular failures of most swing wave indicators are mitigated when the expected price turning point does not occur.
Although Dr. Ehlers admitted he had not studied it extensively, it appears that the Even Better Sinewave Indicator works well on futures intraday data. It takes a position in the correct direction and tends to stay with the good trades without excessive whipsawing.

[blackcat] L2 Ehlers Autocorrelation ReversalsLevel: 2
Background
John F. Ehlers introduced Autocorrelation Reversals in his "Cycle Analytics for Traders" chapter 8 on 2013.
Function
One of the distinctive characteristics of autocorrelation is that the autocorrelation shifts from yelow to red or from red to yellow at all values of lag at the cyclic reversals of the price. Therefore, all we need do to determine these reversals is to sum the bar-to-bar differences of the autocorrelation function across all values of lag. When the sum is large a turning point has been identified.
The indicated reversals are very sensitive to the smoothing of the price data. Therefore, the LPLength is made available as an indicator input to decrease or increase the number of indicated reversals as desired. The AvgLength parameter is also made available as an indicator because this averaging also impacts the number of indicated reversals. Care should be taken when increasing the value of this input because the lag of the indicator increases in direct proportion to the increase of the value of the AvgLength. Typical delay of the indicator will be about three bars when the AvgLength parameter is set to a value of 3. The HPLength parameter is also made available as an input for complete flexibility of the indicator. However, changing its value has a relatively minor impact on the indicated reversals.

I am selecting and contributing some of the hundreds of scripts to publish in Tradingview community. Welcome everyone to interact with me to discuss these interesting pine scripts.
The scripts posted are categorized into 5 levels according to my efforts or manhours put into these works.
Level 1 : interesting script snippets or distinctive improvement from classic indicators or strategy. Level 1 scripts can usually appear in more complex indicators as a function module or element.
Level 2 : composite indicator/strategy. By selecting or combining several independent or dependent functions or sub indicators in proper way, the composite script exhibits a resonance phenomenon which can filter out noise or fake trading signal to enhance trading confidence level.
Level 3 : comprehensive indicator/strategy. They are simple trading systems based on my strategies. They are commonly containing several or all of entry signal, close signal, stop loss, take profit, re-entry, risk management, and position sizing techniques. Even some interesting fundamental and mass psychological aspects are incorporated.
Level 4 : script snippets or functions that do not disclose source code. Interesting element that can reveal market laws and work as raw material for indicators and strategies. If you find Level 1~2 scripts are helpful, Level 4 is a private version that took me far more efforts to develop.
Level 5 : indicator/strategy that do not disclose source code. private version of Level 3 script with my accumulated script processing skills or a large number of custom functions. I had a private function library built in past two years. Level 5 scripts use many of them to achieve private trading strategy.
[blackcat] L2 Ehlers Cyber Cycle Trading StrategyLevel: 2
Background
John F. Ehlers introuced Cyber Cycle Trading Strategy in his "Cybernetic Analysis for Stocks and Futures" chapter 4 on 2004.
Function
With cyber cycle alone, the Trigger lags the Cycle by one bar, so that their crossing introduces at least another bar of lag. Finally, Dr Ehler concluded that we can’t execute the trade until the bar after the signal is observed. In total, that means our trade execution will be at least four bars late. If we are working with an eight-bar cycle, that means the signal will be exactly wrong. We could do better to buy when the signal says sell, and vice versa.
The difficulties arising from the lag suggest a way to build an automatic trading strategy. Suppose we choose to use the trading signal in the opposite direction of the signal. That will work if we can introduce lag so the correct signal will be given in the more general case, not just the case of an eight-bar cycle. Therefore, the Cyber Cycle trading strategy was introduced by Dr. Ehlers. It starts exactly the same as the Cyber Cycle Indicator. Dr. Ehlers then introduce the variable Signal, which is an exponential moving average of the Cycle variable. The exponential moving average generates the desired lag in the trading signal. The relationship between the alpha of an exponential moving average and lag is alpha2 = 1/ (Lag+1). This relationship is used to create the variable alpha2 in the code and the variable Signal using the exponential moving average. The trading signals using the variable Signal crossing itself delayed by one bar are exactly the opposite of the trading signals I would have used if there were no delay. But, since the variable Signal is delayed such that the net delay is less than half a cycle, the trading signals are correct to catch the next cyclic reversal. The idea of betting against the correct direction by waiting for the next cycle reversal can be pretty scary because that reversal may “never” happen because the market takes off in a trend. For this reason Dr. Ehlers included two lines of code that are escape mechanisms if we were wrong in our entry signal. These last two Signal lines of code reverse the trading position if we have been in the trade for more than eight bars and the trade has an open position loss.
