I mainly focus on the trading in futures markets. Some instruments have a wide history price range. So the fixed pips SL and PT is not very suitable.
But there is a small problem with the current implementation of SL and PT, Because it will calculate every bar.
IF we use ATR or indicators for initial stop loss,
1, Reward-risk ratio will change.
2, Initial stop loss with only atr will have minor adverse move.
3, Initial stop loss with indicators will become to be a trailing stop, That will weaken the effect of the exit rules or the trailing stop method, or cause logical confusion.
I have post it in forum too.

We can set fixed initial stop loss and profit target in Multicharts, before or at the same time of entry. I have tested it many times and it should work this way without problems.
Please reconsider my suggestion, thank you.
