I have started with a simple trigger adapted from one of the examples.
To start I restrict the trigger to horse races from Australia, win markets.
It is designed to back and lay any selections from a text file, sels_rb.txt, based on a price associated with each selection.
This file has a list of runners each with a rated price, in the correct format.
Lay: With 5 minutes to go, if the available lay price is less than or equal to 10.00 and the lay price is less than or equal to my rated price less 33%.
Back: If there is at least 30000 matched volume and back price available is more than 33% above my rated price.
Outcome: Lay bets are made as expected but none of the expected Back bets are made.
I have attached my trigger so far and would like any advice as to why back bets are not being made.
