Just looked at your monthly profits again and what bothers me is that although your daily profit shows 0.22%, the monthly profit shows a minimal profit for the last 2 years. It seems that the main reason for your pretty decent daily profit comes from the first 2 years of running this EA; especially the first month you ran it (65% profit).
So it seems you dialed down quite a bit on the risk, making the EA look stable long term. If I actually analyze just the last year (2019), your daily profit seems to be only 0.02%.
It's all about the algorithm of myfxbook, not about our profitability. Myfxbook calculates risk that depends on the current balance. For example, I have an account of $1000 and in the first month I have earned $1000 - it will show that my profit is 100%. In the next month, I have $2000 (1000 deposit + 1000 my previous profit). But I have not increased my lots (risks) and earned $1000 once more - at this time, myfxbook will show, that my profit is 50%. We have the same profitability in money, but in % profitability is lower, because the account is twice bigger now.
It's because myfxbook calculate daily, monthly profitability with an algorithm that is working right only with compound interest (increasing risk when deposit is getting bigger). At our account we didn't increase risks (lots) when the deposit is getting bigger.
That's the reason why our daily, monthly profitability in % looks decreasing, but actually it is on the same level almost all the time - only at the beginning of the account, we have higher risks. You will see it if you will analyze our profit in money.
You can easily check all my words by yourself at myfxbook parameters. Just go to the monthly tab at the bottom and click on the button 'More' and select 'Profit'. You will see our profitability in USD for each month. I have attached a screenshot.
Also, you can take the total profit of account 2194% and divide it on the total amount of trading months and you will get monthly profitability - you will see that monthly profitability will be much bigger than showed myfxbook.
