Unfortunately I have not had consistent success on horses or dogs(tennis is reasonable so far) and get burnt fingers now an again (never code and beer) 
Anyway, thought someone might like to get some ideas (or at least a few chuckles)from this one-you will note that I pilfered a few ideas from Dallas-thanks Dallas .Anyway-hope this helps someone to point to profit.PS: Mentioned this before but being able to record the price you matched at so you can track + or - ticks from where you got a match seems to make sense to me as a future update to Bet Angel. happy botting....
PPS:Any suggestions or pointers welcome.Tunnel vision-it's a thing
Might post a few more if there is interest....
but here it is as an exercise anyway
Especially interesting since one of my baf file conditions is that matched bet amounts should be 0 before acting to avoid this very situation .The dog won but since I was heavily on the back side..winner winner chicken dinner..lucky..on dogs! go figure! I put it down to Australian network latency but not detecting 4 or 5 matches ..must have been one hell of a latency issue.I was only gone for 5 mins too.
..monitoring that one
I know I've wondered over the years. Hopefully I am not being premature but I can feel patience in my analysis and bot writing now that was never there before.
