I have two definitions of trend I wish to test to see if trend qualifiers increase accuracy and two different types of setups that I will use (same setups for each trend criteria). I also wish to incorporate 3 different money management strategies to see what would have performed better. all in all out (scaling in only with really strong trend and another signal), scaling out, and both scaling out and scaling back in with new signals (if it happens). The money management strategies stats, however, are not as important to me as the other stats. My time frame is a 0-a few days if stock doesnt act like I want and possible 2-4 weeks on average if it does. I am a swing trader in stocks and I trade with the trend and do better in a trending environment. I have no backtesting experience, I will be backtesting by hand. How many stocks do I need in my analysis, how many months back, how many total trades to give me at least somewhat an idea of how I can expect my system to perform. And anything else? I figure I can crunch about 100-200 setups in a weekend without gouging my eyes out. So in a month I could have a sample size of 1000 trades. Thanks guys.
