Watching SHIB closely after today's low

I'm keeping an eye on $SHIB after it touched 0.00000419 earlier today. It's a pretty critical retest of that range's lower bound, and while it's bounced slightly, I'd be looking for a sustained hold above 0.00000420 into tomorrow. A break and close below 0.00000418 would certainly invalidate any near-term bullish scenarios for me and could open up a move to fresh lows.
