We are trading right now at the exact spot that the market opened on the gap down day 2/24/2020. The gap has now been filled from below and from above and I believe there is huge support here.
The good news is that a 5 year old can see the support you refer too. Huge support? Not according to volume (which is currently elevated/rising)... Your reference point was very near the start of the selloff.
If your expectation fails, you are looking at 3130 (or so), and if the current parallel channel is used, you are looking at 3000 or so for (just) touching the lower channel trend line. 2750-2800 is significant support below there, imo.
Good trading to all.
