I have begun to realize more and more how much position sizing can effect your results. I am trading at a futures trading office that promotes cutting your postion size when you are trading poorly or losing and moving it back up as you are trading better. This is in a non automated environment so there is plenty of discretion involved for the trader to figure out their trade signals and money management. However the difficult part is to come up with the best solution for dynamic position sizing while trading intraday. From what I hear what the poor money management strategy use to be was the they traded small during the day and sized up for the somewhat "free money" news events. Anyway that for the most part is over with. So I guess the trick becomes how to adjust your size during the day. For instance if a trader starts off the day trading 10's to me it does not make sense to cut this size in half after your first loss or two but some traders do that. To me that seems like you are trying to predict when your winning trades are going to occur. Say you have 60% win ration but out of your first 5 trades you have no idea if the first 2 are going to be winners or losers. If you cut your size in half you are not even giving your trading strategy and odds a chance to work for you because by the time you come to the winning trades you no longer have the size to make back what you lost. So how are others going about adjusting their size up and down during the day depending on winning or losing trades? Do you just maintain the same size and have a cut off point for the day if you hit it? IF you start sizing down at some point what gets you to start raising it back up so you can actually take advantage of trading opportunities to get in the black rather then to just get even?
