Betting trigger

Hi, can you make me a trigger please:

Trigger counts money available at back (left side). Works on under market. But in odds brackets. Lets say counts money between 1.05 - 1.1. 
If there is more than - lets say - 10k - trigger will immediately take first lay available, so would lay under at 1.11 as on picture.

Counting money starts at a minute I set.

Trigger works in-play.

Hello,

Please find your triggers file attached.
The minute and sum of the amounts offered are constants at the top of the trigger.
Let me know if you need more assistance.
