So something I thought about on the weekend that I need to backtest but may be a very useful guild for pointing out very overbought conditions in the future. 

You've probably seen folks look at things like when the SPX gets X% above the 200 day MA such as 8%, price is too stretched etc. However I had a novel thought about doing the same with our DVT higher low stop system.  My thought is that if the current price of the SPX is too far away from the previous DVT higher low stop that things are too stretched and due for some reversion to mean action and that is probably a LOT more powerful than simple things like looking to see how far the SPX is above it's 200 day MA that is commonly used. 

Here's a couple charts, for example currently the SPX is about 7.3% away from the last higher low DVT stop on the daily chart. On the daily SPX the daily DVT is still way down at 2856 because that's the last time the fast response BPT changed colors, that's over 225 points away or 7.34%.  Obviously on a 2hr time frame it's very tight but I'm discussing the daily. In my observations typically your DVT's only tend to be about 2 - 3% away from current prices.  Also I noted that end of Jan 2018 it was also 7.3% away.  Typically price only gets to around 5 - 5.5% before you get some pullback so 7.3% is quite stretched, for example what you had in early May this year before that correction

anyway I need to write an alogrythm to test the back history on this so that we can have hard data, however it's something I thought I would point out that I thought of last night about 1 am. LOL I got up and wrote it down so I would remember to look at it today. My brain is always working
