Oh my lord....Breakout of a two year base, page-18

...here's what I find assuming about TA from the graph posted at 11:18am...the blue line curves well below the actual SP from Aug17 to Aug18...yet I reckon (and am happy to be corrected), in smaller time-frame graphs, the blue line would arch way closer to the actual SP....why do that? It seems any approach could get 'effect' you wanted. The 'breakout' of May20 throws it all out of wack, surely...and that's based on the FA, is it not? If so, what 'blue line' is really useful now...?
