Keep In Mind that this strategy executes 1 day later than the HA Arrows script linked above. This is because TradingView waits to confirm positive signals 1 bar after the signals are produced.
Presumably, the actual HA Arrows script will be more profitable than the strategy presents it to be, because they are produced 1 bar sooner on each buy/sell signal.
Also note, by default the script will strategy test with $50,000 starting from January 1 2018 until current day. This is adjustable in the settings, so you can strategy test any date range you like, from 1/1/2015 - present.
