Hi
A lot of the prices in your file are not valid Betfair prices. For example, one of the ranges you have is 3.86 3.97. These are not valid prices. The actual range that falls within your range is 3.90 3.95. It will be much better if your ranges use correct Betfair prices. The tick increment sizes for Betfair markets are:
Price Tick increment size
1.01 to 2 0.01
2 to 3 0.02
3 to 4 0.05
4 to 6 0.1
6 to 10 0.2
10 to 20 0.5
20 to 30 1
30 to 50 2
50 to 100 5
100 to 1000 10
You will need to check your trigger logs to see why the six selections that were within your ranges were not bet, but I think what I have explained above is the reason.
