I'm using a simple algorithm based upon a measure of price momentum that I cooked up (volume occasionally enters the picture as well). The method for determining potential trades is mechanical, but, I never built sizing & risk management into the model - that remains discretionary. So, the methodology demonstrates a sound historical basis, but hasn't been 'formally' backtested. I hope that answers it.
