Quote from psytrade:
ecritt is the author of the trend following on stocks paper, he may have forgotten to mention that.
I tested it myself and found using basic rules like he did, that the drawdown was higher than suggested. I contacted him and then
determined that certain proprietary details were missing , and in my mind key to pursuing such a strategy- the position sizing on entry is dynamic and not static. That changes the results significantly. I have not found improvement changing the position sizing via scaling in, but apparently he has. They are smart and Tom Basso is an investor, of Market Wizards fame.
The work is legitimate and easy to code if you have a suitable portfolio level backtester. Doing the scale in modifications is beyond my current capabilities however, but I did develop my own trend following system that worked well without scale in.
