Good morning, i thik this is right section for this question, if not sorry.

As in title, I ask for a suggestion on a pay site ( i think there are no gratis ones) that permit to create strategies and send notifications when conditions are satisfied in a match to use this in trading on exchange.

Ideal should be a site that permit to create as pre-matches strategies as live ones as combined pre-matches and live stats, with option to choose only matches available on betfair to have notifications only for them. A backtesting service will be ideal, too

I used for years Footyamigo, that has many of these required functions, but lately worsened with lot of malfunction, problems not solved,help for customers no more exist ( i think they changed owner), for example in last days my account simple stopped to register and send notifications, etc.

I know Goal profit but not convinced, i tried others, but problem is that noone has almost all functions and stats required as footyamigo was near to have.
Some permit to build live strategies and pre-match strategies but not a combination of both stats; some have backtest available for live and not for prematches, other have the inverse; noone has option to select in strategies the option to receive notifications only for matches offered by betfair, and so on.
Something as this exist or is only a my dream?
Thanks a lot in advance for Your suggestions
