today I'm glad to present you an indicator which calculates Moon Phases and let's you backtest the simplest strategy over it: buy/sell on full moon and do the opposite on new moon.
This is a public free indicator based on the public one by @paaax:
I added my usual backtesting logic, plus some more customization inputs for easy coloring.
Simple Moon Phases Strategy
This strategy is very basic and needs some filters to improve results. It was created to test the Moon Phase theory compared to just a buy and hold strategy and it did not beat the buy and hold. However, if you flip the entry and exit signals to the opposite signals it performs a lot worse, so there might be some validity to the Moon...
