Well if only it worked as well as you describe, we'd all be rich! I'm not sure if there is any way to spot this on a chart with precision. Now maybe there are better footprints in the options world, because I do hear there are nuggets of gold here when you analyze different strike prices and expiries, etc., but strictly looking at futures, I'm not sure. Any time you get an entry with more confirmation, your price risk is going up.
Looking at your chart from this post,
https://www.elitetrader.com/et/threads/the-s-p-has-topped.307293/page-19#post-4419505 , it still looks like a runaway bull trend, but if we focus on the lows in 2009, one week bar was down, next week bar was up, and then it was up all the way from there without ever looking back or being tested. Surely there had to be shorts closing, longs opening, and deep pockets moving in there are well, but how to see? In fact, even just analyzing the anatomy of intermediate tops and bottoms on this chart, there is a whole range of what can happen at a top or at a bottom, and there is no clear market structure that tells you. Sometimes you get a bull/bear reversal bar side to side, sometimes you get a test like a double top or bottom, and sometimes its a "pin" bar with a very long tail, but each instance of top or bottom is different.
If going just based on visual cues, the runup since the election in November seems to be the most acute run higher out of anything on that chart, and based on this, ready for a deeper pullback since there is no other run higher quite like this one without a pullback. (but of course going on just this would be foolish)
