Hi all,
So, say I have a certain system which I tested back on data a soccerseason of previous year. My system is based only on putting in money on certain clubs winning. Other outcomes are 2 clubs drawing or a lose, so only a win for a certain club I bet on means a succesful bet. I have a total of 600 matches over the whole season, of which 58 were eligable for my system (meaning 58 is also my samplesize). Over this samplesize, assuming I put 1 unit on every game, I had a succes/returningrate of 20,6 percent (meaning, say I put 10 dollar on every of the 58 matches, my investment would be 580 dollars and my total returns around 700 dollars).
Now, I know 58 isnt a very large samplesize, so I wondered: What would me a good samplesize for testing back my system and how do I calculate the errormargin given samplesize is 58? Thanks!
