Adding the next day's races should not restart the triggers. The triggers will be restarted if you manually hit the "Reload" button or if you restart MF Pro itself.
The triggers will act anew in a race if it has been deleted then reloaded by Market Locator -- that's true. But to avoid this, you only need to untick "Clear My Markets first" in the Market Locator search template.
If you want to resume a loss recovery after restarting the program, that's another story. In this case, you would need to add current_lss, win_cntr, lss_cntr and other user variables as constants, initialise them with starting values, and change "Start with initial value" to "Remember last value".
