Back tested system US Open 12 % yield, 12 years

[gonza3591]

So i found this site tennis data.co.uk download the result and odds for the last 12 U.S. Open, and tried to make a system based on bet in every match, chosing a minimum and maximum range of odds for favorite and underdog, and finally i think i got it. The thing is bet on underdog in certain range of odds depending if its the 1st round, 2nd, 3rd, semis...You can see the range of odds in the excel file. For chose the range of odds, write a macro who do it automatically, searching for the maximum profit, so its very easy. Then i back tested the system, copying the main file to another 10 and moving in every book, one year out of the range taked for the macro, so the good or bad profit in that year doesnt change the range of odds. And finally it goes from 169 bets and 25 % yield in the main file, to 133 bets and 12 % yield after back test the system Anyway i also tested the system in wimbledon, french and australian open and they were big losses, so i just let this here and you can give it a try, give your opinion..This was just made in 1 hour, while i take a rest from other project so im not 100 % sure the system works fine http://www.mediafire.com/download/yl1em9q1gdldnjn/Tenis(2).rar Sorry for bad english

Re: Back tested system US Open 12 % yield, 12 years Back testing is absolutely worthless, since you already know the results of the matches. Do yourself a favour and don't bet this system.
