Hi MarkV,
Thanks for that reply. The scheduler looks like it will do the trick, at least for the simple stuff I'm going to initially try.
I have not tried the software yet, I've gone through some of the manual and it looks like MarketFeeder does everything else I want, I just didn't see the bit on the scheduler.
I could develop an app to place bets using the BetFair API, but would rather pay someone else to maintain and test that code and hopefully do a better job than I could.
