Understood. I look at mvp's intratrade draws on original buys with the same thought, but have never found a way to apply what you said that would not end up 'reducing' profits.
By that I mean, you bail out at X and re-enter at Y, and just cost yourself Z if you had just 'stayed the course'.
One real life real$ example, the current trade was down 26% during the worst of the subprime august meltdown. Yet, right now, the same trade is up 19% and has already pocketed 2 rounds of open-close-donepiggyback trades.
Last but not least, as I have always contended, mvp draws are a lot easier to 'stay the course' with if you're me, ie wrote the program and can look over the 10+ year history any time theres a draw and see all the prior ones and how they made out.
