New TA/Charting, page-14424

Correct me if I’m wrong, but you have used the chart pattern of an “Ascending Triangle”, which happened to work out just fine, because it’s target is as the following image, the hight of the triangle added to the breakout line.

I’d suggest a new chart pattern would be required to explain the SP drop from the high and IMO the indicated ABC doesn’t quite cut it, especially not from where you indicated the start of it. I’d suggest to use the weekly or daily chart to get more detail …
