Currency StrengthRepublished: The original script violated house rules by including an external link to Backtest Rookies. Background The currency strength indicator takes up to 4 forex pairs and calculates the average strength across all pairs. The indicator uses the pair's daily percentage change to calculate the overall strength. For flexibility, it can accept any instrument as an input. This means you can use multiple instances to track various currency strengths. It was designed with the major pairs in mind but there is no reason why it cannot be used for other FX pairs. Note: The indicator defaults to GBP. When setting it up for other currencies, be sure to flag whether the currency is a counter currency or not. The code is provided free and open source. Please modify it as you see fit. Screenshots Defaults with Annotation Yen strength beating pound strength Opposing Trends

Multi SMA'sRepublished: The original script violated house rules by including an external link to Backtest Rookies.

It also has a couple of features that let you mix time frames and de-clutter the chart. The code is open for anyone to modify and a copy About the Indicator Although the indicator does nothing more than it says on the tin, There are a couple of points worth mentioning: The indicator will let you view up to 4 SMA’s You can set the period for each SMA independently You can set the resolution for each SMA independently (So you can see the see the daily SMA level when on the 15-minute chart for example) Each SMA can be turned on/off independently to avoid clutter.

Backtest Strategy Optimizer Adapter - Supertrend ExampleSample Code This is a sample code for my Backtest Strategy Optimizer Adapter library. You can find the library at: Backtest Strategy Optimizer Tester With this indicator, you will be able to run one or multiple backtests with different variables (combinations). For example, you can run dozens of backtests of Supertrend at once with an increment factor of 0.1, or whatever you prefer. This way, you can easily grab the most profitable settings and use them in your strategy. The chart above shows different color plots, each indicating a profit backtest equal to tradingview backtesting system. This code uses my backtest library, available in my profile. Below the code you should edit yourself You can use ChatGPT or write a python script to autogenerate code for you. // ################################################################# // # ENTRIES AND EXITS // ################################################################# // You can use the link and code in the description to create // your code for the desired number of entries / exits. // ################################################################# // AUTO GENERATED CODE // ▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼ = ti.supertrend(10, 0.1) = ti.supertrend(10, 0.2) = ti.supertrend(10, 0.3) = ti.supertrend(10, 0.4) // 005 etc... pnl_001 = backtest.profit(date_start, date_end, entry_001, exit_001) pnl_002 = backtest.profit(date_start, date_end, entry_002, exit_002) pnl_003 = backtest.profit(date_start, date_end, entry_003, exit_003) pnl_004 = backtest.profit(date_start, date_end, entry_004, exit_004) plot(pnl_001, title='0.1', color=backtest.color(001)) plot(pnl_002, title='0.2', color=backtest.color(002)) plot(pnl_003, title='0.3', color=backtest.color(003)) plot(pnl_004, title='0.4', color=backtest.color(004)) // Make sure you set the correct array size. // The amount of tests + 1 (e.g. 4 tests you set it to 5) var results_list = array.new_string(5) if (ta.change(pnl_001)) array.set(results_list, 0, str.tostring(pnl_001) + '|0.1') if (ta.change(pnl_002)) array.set(results_list, 1, str.tostring(pnl_002) + '|0.2') if (ta.change(pnl_003)) array.set(results_list, 2, str.tostring(pnl_003) + '|0.3') if (ta.change(pnl_004)) array.set(results_list, 3, str.tostring(pnl_004) + '|0.4') // ▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲ // AUTO GENERATED CODE // #################################################################

QFL single TF with alertsBacktesting compatible QFL pine script w/alerts This version of QFL was made based on this one: From author: www.tradingview.com I made the following additions according to my requirements: - I need to use pine script 4 - I needed to avoid repainting issues so I'm not calling directly security, I'm using the wrapper function. - There might be still repainting issues when you use "max base age" which uses the function "barssince" so be careful, you can disable it by setting its value to zero. - Alerts so I can use it for automated trading and bots - In order to make this signal compatible with the backtest script there's an option provided in the settings. If you enable this option this indicator will plot 1 whenever there's a BUY signal. This will allow the backtest to pick the "QFL Buy" from external indicator so it can perform the backtest. I recommend some of these settings to start playing with the chart in 15 min / QFL in 1, 2 or 4 hours. The higher the TF the more conservative. QFL with 3.5% is pretty popular but you can try higher QFL percentage settings for a more conservative approach.

Backtests Are BrokenThis script demonstrates a fatal flaw with Trading View backtests involving trailing stops. Trading View assumes the most optimistic case for trailing stops, always giving you the best case high/low of a bar instead of the worst or average case. Within a bar, the price could reverse against your position after the open and trigger your trailing stop for a loss before the price goes in your favor, but Trading View backtests do not consider this and instead always give you the best case returns. This allows a trivial strategy to appear as though it would perform miracles. This strategy enters on a random bar and sets a trailing stop triggered one tick better than the current price with 0 trailing distance. Trading View then generously gives this strategy the difference between the open price and best possible wick as a profit. The only way this strategy can lose money in simulation is if the price goes straight down after entry and never retraces. It works on all symbols on all timeframes due to this systematic problem with the Trading View backtester.

Backtesting Period Selector | ComponentDescription It's nice to quickly be able to set the backtesting period when writing strategies. To make this process faster I wrote a simple 'component'. So this is not a strategy but rather code you can plug-into your strategy and use if you need that specific functionality. Then it's just a matter of selecting which dates you want to backtest. You can also chose to color the background to visually show the testing period. Unfortunately, the background color is fixed at 'blue' for now. Ps. I like the idea of writing small components to be pluged into other strategies I'll try to develop this idea a bit further and see how small pieces of code can easily provide specific functionality to assist and make deving strategies a bit less 'Pineful'. Usage First copy the instructed part of the component code over to your strategy. Next, use the testPeriod() function to limit strategies to the specified backtesting period. Example usage: if testPeriod() strategy.entry("LE", strategy.long) Todo / Improvements There are many ways to improve this component and I'm not a very good coder so this is a very crude solutions. Anyway, here are some things which would be nice to improve: 1. Enable color selection so that the user can choose the background color of his own liking. 2. Improve naming of variables. 3. Test for ilogical choices, such as test period start being at a later date, than test period stop. 4. Account for time zones. As always, any feedback, corrections or thoughts are very much welcome! /pbergden
