sdoma, in your example, if you limit the days with more than 4 losing trades, you also limit the days where you turn around and have a number of winning trades turning the day day into a winner.

As stated before, if you have a system that has a proven edge, then you should take every trade the system offers unless you dont think you can execute the trade inline with the system.

Also, if you stopped after the 4 losing trades, you will likely increase the number of days with 4 losing trades as the system has to balance out.

i agree with Russellhq that you need to look deeper into it and be able to track which days then also reverse. Additionally you have to be careful that each day does not start with a succession of losses as you start the process each day.....so I guess in statistical terms the series of trades becomes a series of series of trades (??? not sure if thats relevant )

Point for all of this is that no one system will work for everyone or every style or strategy.

I was wondering about this the other day when discussing a martingale strategy with someone with a slightly different twist. This was spurred on by a discussion around position sizing based on the number of losses you have........

Basics were normally you trade 1 contract, but every time you get it wrong and stop yourself out you increase the size of the bet for the next new trade.
eg; buy 1, stop out, next time buy 2, stop out, next time buy 3, stop out, next time buy 4 - win. Next trade buy 1 contract.

Now of course this is system dependent, my guess it would work well in, requires more trading capital than many would normally have and would still require limits on the total volume, would probably be mentally tough to do and the obvious thing is that you will be disappointed if you get a 90% win rate as then you never really get to increase your size ......

I was wondering if any one has tried this, or been able to model it properly (I dont think I have the time but might one day to do it properly).....it was just a thought.
