Hi
If you want to specify a market and selection to bet e.g. OU2.5 and betting on Over then use these conditions:
markets betting code is Over/Under (Soccer) 2.5
and selections index is equal to 2
If you want to check a variable in OU2.5 from another market in the same game then use football8_ prefix e.g.
selections trigger expression football8_market_volume is greater than 1000
