Nifty's low of 2nd july was easily predictable

Simple use of trendline could have helped in determining the same. I have connected the low of 27th May and 21st June 2021, and have produced the line further to the right on an hourly timeframe.

I made this line two days back and had the view that Nifty has to turn bullish on the first tick, however, it turned bullish after exactly touching the support line.
