_alerts += "On the pair "+PositionList[i].symbol+" the stoploss was changed from "+ PrevPositionList[i].sl +" to "+ PositionList[i].sl +"\n";
This is not an error but a warning that this line contains an implicit conversion of a number into a string. In such cases, the compiler warns about the conversion, and the programmer must decide whether this conversion is an error or not.

The article does not cover the closing of positions with take-profit and stop-loss. Only the events indicated at the beginning of the article are considered.
I see, it's a pity that they are not considered. I will wait for a similar article to appear or you will add your own in accordance with it. The analogue of the article for MT4 can be found here https://www.mql5.com/ru/articles/1399.
