Force Index with Advanced Features [Quant_]This is the traditional Force Index indicator developed by Alexander Elder and described in his book "Trading For a Living" . As you probably know, the Force Index measures the amount of power used to move the price of an asset. The formula is pretty simple - the difference between the current and the previous close is multiplied by the volume of the current close. However, I wanted to add some additional features to the indicator, so that you have more control over it. Improvements include:
- Choose the length of the Force Index
- Choose the time frame of the FI (you can choose a smaller time frame and get a more detailed overview);
- Smoothing of the results through a Moving Average (Simple, Exponential, Weighted, Running or Hull);
- Choose the time frame of the smoothing MA for even greater control;
- Color changing depending on the increasing or decreasing smoothed Force Index;
I used to use Force Index for spotting divergences and exhaustions and it worked pretty well, but it does require some time until you get used to it. Bear in mind that you shouldn't jump against the trend on every divergence that occurs, but use it as a complementary indicator to your trading system. I am planning to add some additional features to this indicator to make it more robust, so stay tuned.
I hope you find this indicator useful. As usual, if you have any questions or suggestions on how to improve my indicators, please let me know. Thanks.

Force IndexWhat is the force index ?
The force index is an oscillator used to confirm price breakout strengths and identify potential trends.
It was popularized by A. Elder.
How the force index is computed ?
Knowing that volume is the fuel of a price movement, reliable breakouts and trend continuation are more likely to occur on high volume breakouts. This is why the force index is computed with the intensity of the price movement, and it's volume , using the formula ema13((close(n) - close(n-1)) * volume ) .
How to use the force index
An important change in the force index indicate a strong momentum in the price action.

Customization
You can display the indicator as an histogram, or as a line chart.
You can change EMA length, although it's recommended to keep it at default value.
Elder's force index impulseForce Index is an oscillator. It combines volume with prices
to discover the force of bulls or bears behind every rally or decline.
It brings together three essential pieces of information the direction of price
change, its extent, and the volume during that change. It provides a practical way of
using volume for making trading decisions.
Force Index can be used in its raw form, but its signals stand out much more
clearly if we smooth it with a moving average. Using a short EMA of Force Index
helps pinpoint entry and exit points. Using a longer EMA helps confirm trends.
Efi long > 0 (bullish trend) and efi short < 0 = buy signal (green bar)
Efi long < 0 (bear trend) and efi short>0 = sell signal (red bar)
