Slight update to the idea!!
If the upward trend line is broken on Monday morning and we continue to see it moving down aggressively, I am expecting it to bounce up in the case of SPY at 515 and at 90 in the case of Nvidia, so then as I am a daytrader, it would be short on Monday first and then a long from 90.5/515. I will have to see how this bounce proceeds in a possible uptrend, but for now this does not mean that the correction mentioned will, not happen. It will just be on hold till we reject most probably on the levels mentioned earlier, or maybe a bit lower, I see 122 for Nvidia, SPY most probably at 558, before continuing the trend downwards.
I will keep updating this idea as we go, but I did want to mention this possibility of continuing down, before we bounce up from these mentioned levels.
