Indeed question everything ?_?         TA on a basic level is record keeping, statistics, counting averages.     Nothing wrong with that or especially distorting but when people draw conclusions from a moving average, thats opinion.

TA can just be maths, nothing that evolved from the price especially.   Extrapolation is estimating based on previous prices, its not unreasonable nor is it ever entirely accurate.   I prefer stats to guessing though



Blue line is a 8 day average.   Horizontal lines are % of previous highs vs lows.    Green bar means it ends the (4hr) time period higher then when it started, red is a drop over this time.   The lines on the bar are prices in that time seen but did not stick, the bar bottom to top being the start and end of the price move
