%% Meaning close on or above 50dma....................................................................; based on close price.[Some use a settlement price, I prefer close my self as op hinted .There is some wiggle room============== simple ma , smooth ma,ex, v0lume weighted ma..........+ different chart services have a bit ao a differ on those exact #. If that is confusing just use a exponential 50dma/200dma ex ma....................................................................
exactly - no one can define, measure or substantiate "hold the ma, or to hold support or hold the dp" nor can they define to "break the ma, or support or dp". Remember: a thing that cannot be measured cannot be understood and discussing a dma is foolish and without trade understanding. Same can be said for channels (Keltner, Donchian), horizontals (highs, lows, etc.) and curve-linear (Fibo lines).
Well, that is something that comes with experience. You cannot be profitable from the very beginning.
