France??? (what's that all about?)
I had considered that Betfair would soon know of a profitable user and can't see how they
couldn't resist copying their betting patterns...
As for the MFP ready made triggers, use them to adapt to your own manual profitable system (if you have one) or use them to try out ideas you have in test mode or small stakes 'live', lets face it, if it was that easy, everyone would be doing it.
It's also essential you run a trigger for several weeks to iron out any ups and downs that always occur in racing, to give you a more realistic interpretation of whether you can make any money long term...
