    Then it's an issue of the signals generated by the system. If it's not good enough to identify the false signals from the good ones, then the system is just not good enough unless you can design it in a way that its profit potential when the signal does turn out to be right is significantly higher than the losses that could be incurred from the bad signals. Limiting the number of trades is not a good option because if you limit the number of trades then you are also eliminating the potentially profitable trades. Seeing your system is anchored on higher number of trades then you have only two options:

    1) Maximize the win/lose ratio or

    2) Maximize the potential profit/loss ratio for EACH trade

    Maximize both of course would be the best. If you can't maximize either one of them, then ES is just not a good instrument to trade. IMO.

    Agree, I know I can improve both within the system. Without hard data, I estimate W/L ratio can go up proportionally, about 15% over all market conditions that are specified. And I can see profits/loss going up to more like 1.75 to 2 points. Of course 1 helps 2. The reason I have not is I was following the system as spec'ed to get a good baseline. Now I will start the optimization phase with incremental changes. Fortunately, ES behavior as targeted, is not going anywhere. Thanks.

    To me, an increase in win/lose ratio does not necessarily improve the profit/loss ratio. I find they are quite independent. You can have a system that allows you to win quite a high number of times but your profit each time is not large vs the loss that can happen. So comparing to a system that does not have as high of a win/lose ratio but when you win, your profit vs loss is much higher, you can still end up with higher overall profit but you need to have higher trading capital and with sound capital management rules to ensure that you would have enough capital on hand to allow you to trade that one finally tremenously profitable trade that makes all your losses back and then some.

  6. waiting to blow up sounds like a very dramatic documentary about a human suicide bomber. maybe thats the parallel. traders waiting to blow up are actually similar to a suicide bomber.

    Only way you blow up is if you size it too big. 12 contracts is what portion of your overall portfolio?

    This is an isolated system. One of many. 12 contracts is with range of the systems designed parameters. "blowup" was loosely used wrt to W/L frequencies relative to W/L size. Sorry for the confusion.

    mean reversion systems all blow up at some point if you don't have stops
