Hi
Yes you are right, it will back "Under" one goal ahead of the current score at the specified time in the game. Since this trigger was written, there is a new variable match_minute which is more accurate, so you could replace:
and selections trigger expression (now_time - event_start)/mf_minute is equal or greater than mso
with
and selections trigger expression match_minute is equal or greater than mso
The trigger bets at the best market back price, up to a maximum price of 1.15, you can change this and the trigger time in the constants.
Most in-play soccer games have the OU 0.5 to 6.5 markets. Specify in the Locator:
markets will turn in-play YES
As stands the trigger will bet in one game and wait until the current game has been settled before betting in the next game. The trigger description shows how to deactivate this to let you bet in multiple concurrent games. If there is a loss using any of these options, the trigger will deactivate and send an email, although if you bet in multiple games concurrently, there may be multiple losses.
I think you could improve the trigger by checking there is a good back book% before betting, and / or a smallish spread between best back and lay prices, though this may prove more difficult in lower liquidity markets.
Please test in test mode.
