Backtest Strategy Optimizer Adapter - Supertrend Example

Sample Code
This is a sample code for my Backtest Strategy Optimizer Adapter library.
You can find the library at: https://www.tradingview.com/script/tsHCuCEi-Backtest-Strategy-Optimizer-Adapter/

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.
