I did a few web searches and as far as I can see the ROI as calculated in my spreadsheet is the way it is widely expressed in the betting world. I cannot comment on how this is calculated in the financial world and as such I will have to take both your words for it. The method of dividing by total capital as opposed to invested amount seems to me to offer little value because imo it then loses its objectivity. My ROI used with standard deviation etc is a superb way to backtest etc etc, I can see little use for a ROI which was composed by dividing by capital as like I mentioned earlier it is effectively a spin on P&l weighted by initial bank size. So your method rewards for the investor getting the stake size correct, whereas my method objectively measures whether the underlying method has an edge.

I have to get back to my bet research and don't want to spend more time writing on this, because I think none of us will ever agree. Will be interesting how the other thread goes.

I think we will agree... in fact I don't think we really disagree, to be honest.

Poor sods will be bored to tedium reading my copy and pastes of bets lol. Though must admit it has been much more interesting in here the last day.

I will try and do a p&l update tonight with POT :rolleyes: :LOL:.

Seriously though, have learnt quite a bit with thinking in more detail about the things that count and why! Just hope I haven't alienated anyone in the process. Sometimes things can come across worse than intended with written word. Anyway... a few horseraces still needing pricing up...

note, Rik de Voest match only just started, sometimes a delay like the match earlier - I get the Est time from a program and half the time want to get the post up before the match starts.
 
every second counts! I am writing this as I see nothing worse than somebody who "after times". See for yourselves for proof if there is any question as to discrepency between est start time and post time!
