When an asset moves 6 Standard Deviations aka: 6 sigma on a 15 minute candle … (and also hits 6 sigma on the 1 hour, btw) … that’s often a good indication that it’s a good area to Take Profits (TP).
And so it was, yet again, with this latest move bit bitcoin , to the upside.
Know your volatility . Understand Standard Deviation of Returns (which is volatility ).
Use proper math indicators that show you things like the Expected Moves, and which even let you manually set one of the STDEVs. I like to keep it between 4 and 6.
