If we are indeed basing and looking for an intermediate term bottom, we should see buying to be obvious in next 1-3 days. Like rocket blasting off obvious with a large daily candle, not just a big gap up. If not, we probably don't have a floor.
VIX in the first resistance zone and printing a reversal candle. The only drawback is oscillators aren't maxed out which does give me some pause.
$VXO looks more promising as a reversal set up
SPY potentially bottoming but needs confirmation
