Hi,
this post is very related to your other post about profiles.
Combining trigger files will cause issues for you in a few areas and is difficult to get right.
It will be much easier for you to check bets, faults, trigger entries, maintain win loss records etc etc by opening a new profile for each system/strategy.
When you are then sure that that each works properly for you, AND you are sure that none of the strategies will conflict you could combine them into one trigger and one profile. But in my experience, different profiles is the better of the two options by far.
