The real key to system development is not be able to find a profitable system but more to find a system that will continue into the future.

The period of testing is irrelevant. It needs to be based on the winners you have found. If the winners are paying a higher dividend you need more winners to be more confident.

The research was to find around 200 profitable systems and then to apply several testing methods to see which of the profitable systems would continue into the future.

I now apply 4 tests to the profitable systems. If they get all the ticks I start to bet on them. All the methods have been discussed on this forum. Many posters said you needed some logic behind your rules. This might be true but everyone knows what is logically and this is overbet. Most systems that are profitable are due to a long-shot winner during the period of testing. Systems that will continue to win also should be very close to making a profit for the Place bet too.

But the Archie Score method is the best! Anything over a score of 7 continues to make you money if it has been in profit during your test period. It doesn't mean a profit everyday or even month it does continue.

I have one system I will share minus a couple of filters as I use this sytem with great success. Probably get slammed but here goes.
