Can an EA also show indicator type symbols without attaching an indicator to a chart?

 

I have an EA and there are several conditions for buy and sell. For simplicity lets call them buy1 and buy2 and forget the sell signals for now.


When I run the EA, either in backtest or forward test, can I get the EA to distinguish between those trades relating to buy1 signals and those relating to buy2 signals buy using an indicator like symbol such as an arrow?


If so how is this possible? thanks in advance.
