BTW, to clarify, the exit as I use it is as follows. We take profits on a chain level when it crosses the previous chain level. So if we are short from 14, 24, 35, we take profits on the units from 35 when the divergence goes back to 24, and we take profits on the 24 units when the divergence goes back to 14, and we take profits on the 14 when divergence goes below 7.
However, I have heard people do things like, only take 24, and leave position on until almost "zero." It all depends on your level of aggression, your instrument, your R/R, etc etc etc. The higher the VIX though, the more killer my system of adds/profits is. Oh high VIX, I have seen it go, 24->35->24->40->24 (add, add, take off, add, take off,...) all in one day! We are gamma scalping without an options position! So I am just raking it in. The lower the VIX, probably leaving all or most of the position on to zero convergence works better. In between VIX like now, eeeeh, leave it alone and use my chain system.
The chain is a guide to both instill discipline and remove fear from people here that aren't used to trading, and to allow some of their own customization preferences based on their account size and risk preferences. The meat is NFV. Without edge, you can stand on your head with any chain imaginable and you will lose over repeated trials.
Note that there is and optimal chain on any given day. But I challenge anyone to know what it is before hand. Yes, I am working on that too...
