In our mad rush to develop the "winning" system some of us fail to consider that AT BEST one will have on average 70 losers per 100 bets.(Av Fav Strike rate..)over the long term.
Ones price will need to be very good to overcome that disadvantage.

In the very short term some will make a quick profit then fail.Others no profit at all.

As a intellectual exercise its fun but far better to put your money in a bank or credit union.

Dont want to put a dampener on the fun side but thats the reality of the punting world.
