Here is a backtest of a trend pullback strategy shown in a YouTube channel using Wavetrend indicator and 200 EMA and Donchian channel ribbon as trend filters.
I coded this strategy in pinescript to backtest this.
The Pinescript code can be tested from this link.
Found this strategy useful only on USDCHF 15 minute chart with an equity curve like one below.
So here is the strategy settings for the above results.
The youtube channels like this one are not doing proper backtesting before publishing some imaginary strategies they think would be profitable.
Simple pinescript can help test these rulesets.
