TT - I agree with your assessment of shorting small caps being one of the best options on the next sell signal. I think shorting midcaps would also do well.
Your system looks like it trades much more frequently than mine. I doubt I will get a sell signal until Jan-Mar next year. There should be several pullbacks to the 50dema between now and then. It looks like the fast easy money for the initial part of this run is over.
