Forever...or at least 13 days!
Amazing how the volatility is still somehow underrated.
If you put an order at $299, there is still some chance for it to be filled when a big negative news comes out.
I think the $300 level is quite strong as the mini dumps only reached $304 and yesterday $310. That alone is a good sign. Whales can dump it below $300 easily, but for some reason they seem to be satisfied with a price above $300.
