What has worked for me so far...and I stress this is not a recommendation to anyone else. I ALWAYS use stops, personally mine are set at -50%. I USUALLY use GTC orders, last earnings season they were set at +30%, and this season I have moved them to +50% based on money that I have left on the table. I never open a CML trade during the first 30-45 minutes of the day. I usually change the back test to use longer options. I have found the monthly options to be better based on volume. I have 2 option trading accounts, SO gets the 10% per trade and no more than 60% total allocation as Kim suggests. In other account I allocate 3% to 5% portfolio value per trade from CML and stay between 50%-60% portfolio value invested. I am new to SO so I can only look at the historical performance which is great and speaks for itself or else I wouldn't be a member. All that being said, my CML performance has been very successful. Last earnings season when I started using it, I ended up +40% for Q4. So far for Q1 2018 I am up 25%. Overall in the money trade accuracy has been 73%. It does take a lot more active account management, and there is a much larger directional risk since all of the CML trades I focus on are long calls. I apologize if you know or have tried similar techniques.
