Hi
Auto-greenup will green-up (or distribute loss according to the settings) on ALL selections in the market as soon the opportunity for green-up or stop-loss occurs. It cannot distinguish bets placed by a trigger waiting for individual green-up or stoploss by another trigger.
Also, auto-greenup does not take into account the spread between back and lay price. It will distribute loss at the first available price in the market.
The only way that I know of that triggers and auto-greenup can work together, is to submit only the opening order with a trigger, and then use auto-greenup to close the trade. Other than that the two don't mix.
