hi,
I am not sure but it looks like a problem I had some time ago. The trigger conditions
21:21:32 Checking condition and Market's Number of Matched Back Bets is equal to 0.
and
21:21:32 Checking condition and Trigger Selection traded out, stop further betting Number of runs is equal to 0.
may be crossing wires somewhere, perhaps double-checking against itself. I would experiment a little and try to get the trigger down to one condition depending on how many selections you are going to lay/back. for example if you are laying/backing only one selection per race then the condition "selections lay matched is greater than 0" might suffice. But it is difficult to be sure without seeing the full trigger which of course you should not post up.
Perhaps do up a sample trigger with the main conditions and post it, someone will have a solution for you
