I started trading with a prop firm in November and now have three months of experience to draw upon. I find myself stuck and I am asking for some input. Currently, I seem to be capable of trading gross positive but have not been able to consistently trade net positive. I made huge gains in my performance from November to December and leveled off in January. In November, I simply was not managing risk properly. I found myself trading too much size and allowing losers to run. I started trading 500 share lots because this is what I was practicing with when I was trading a simulator. I felt comfortable with this size and wanted to change as few variables as possible when I went live. The following were my trading stats for November: Shares Traded 194028 Number of trades 358 Avg per share/trd -0.009650369 Average duration 0:10:26 Gross Loss -1476.996 Winners 202 Avg gain 0.091829624 Losers 156 Avg loss -0.141053949 Win % 0.56424581 Shrt Win 34 Avg gain 0.092352941 Shrt Loss 33 Avg loss -0.161770182 SS Win % 0.507462687 Win >.1 73 Loss >.1 74 Win >.2 23 Loss >.2 40 Win >.3 7 Loss >.3 17 Win >.4 1 Loss >.4 10 Loss >.5 6 Loss >.6 5 Loss >.7 3 Loss >.8 2 Loss >.9 1 Based upon these results, I determined that I took too many large losses. Additionally, in December I dropped my size to 100 shares.
