Long tails, strong buy signal, page-8

See the following

...for me, when I see a quality stock like SBM getting sold off, you can tell (and I use that term loosely!) whether there is strong buying support by looking for long tails, i.e. the tail shows that the intra-day/week low is being snapped up and forms a strong base, or buy signal.

Just a combination of my observations (technical charting) and gut feel.  Seems to be working well for me after years of mixed results.  Portfolio is up 80% since Jan 2016.

Good luck to all.
