I've simulated the bot's behaviour, backtesting MACD strategy, in order to find the best threshold values for maximizing the profit.
Test goes from May 3rd to June 6th.
Seems like positive results are impossible with sampling times inferior to 1 hour. Additionally, best threshold values in this case are threshold-buy=0.6%, threshold-sell=-0.4% so ca. 10 times the recommended value of 0.05 .
This bot is not suitable for fast trading!
Have a doubt...
Idea of method is to trade on the end of corresponding trend. Price at the end of trend is more/less close to extreme. So, the threshold should have value, sufficient to be sure the trend is ended. Absolutely newer about .5-.6%.
Your values suitable for reverse method, where bot try to catch extreme price on trend peak. It's absolutely bad idea.
Indicator is indicator, nothing more. It can be just an adviser for trader. Bot logic should be more complicated then to follow the empiric magic. Suitable conditions not equal the fact. With any threshold value.
