Question for (on trade) or (in loop) ?

[alex222]

Hi @L'ANDORRÀ, hi everyone
I wanted to know if it is correct to use this procedure or if there is another one.
Use Buy entry with stop loss and take profit in pips.
Next I need to know their prices and put them in a variable.
is it correct to use (on trade) event data?
or should I use the (in loop)?

thanks in advance of your reply
