These are my chart studies, in order from background to foreground:
+500-period SMA (thick mud/brown)
+Bollinger bands (various magenta) placed 1, 2, … , 6 standard deviations from 200-period SMA
+200-period SMA (thick yellow)
+50-period EMA (thin orange)
+20-period EMA (thin teal/cyan)
+Heiken Ashi bars
Nothing fancy at all. One great thing this will tell you is when a move is over-blown. Each standard deviation line is like if you took the "bell curve," turned it upside-down, and swept it left-to-right and varied its width with time with volatility. The price is then sort-of like a marble which sometimes gets pulled to one side or another (as if magnetically). Eventually, you'll see a "blowout" and that is a chance for a quick high-likelihood scalp.
