Hi! Can you guys help me a bit?
1. I want to place a back bet on the over 2.5 goals market in the 55th mins when the scoreline is 1:0 to either side. The only thing I cant get right is to fire at that time.
2 If my bet is matched, goal is scored and green shown how to set it to cash out? Also, can I delay the cashout with a few minutes?

You can use "After bet rules->Hedge" and at "Hedge->Market conditions" add two rules:
1. Football - Bet when score, set it to execute on scores 2:0, 0:2, 1:1
2. Market status change delay, set it to wait for X seconds after market changes its status e.g. when goal is scored.
