Unmatched bet at specific odd

[gsa]

Hello!

I want to place a lay bet of GBP 10 at the best and 2nd best price, if a certian condition is met.

So let's say the current lay odds are @ 1.20 (best) and 1.19 (2nd best). So the bot would place a lay bet at 1.20 and 1.19 of GBP 10 each. But I might already have an unmatched bet of GBP 4 (or any other amount) in the market at 1.20 and/or at 1.19. In that case I only want to "fill up" the lay bet on 1.20/1.19 to a total of GBP 10 each. So the bot would only place a lay bet at. 1.20 of GBP 6.
To get this working I need to check my unmachted bets at a selection at a specific price. How do I do that? (I know how to do the rest of the bot....)

I tried it myself (using signals and stored values) and also searched the forum, but still I can't find a solution....

Any help is very much appreciated!

Thanks

Georg
