AMC recently broke out and pushed to the upside of the downtrend., however buyers are still not showing a lot of strength, but this is usually normal during trend shifts. Relatively low volume and volatility, leading to a flatish price usually signals a trend change.
$5.30 has excellent support and I'd imagine shorts will be looking to exit their trade (buy back their shorted shares) if AMC happens to come close to this level. You can see sellers have pushed the price close to 5.30 but buyers have front ran it every time, showing that there is clear demand at this level.
Ideal entry would be 5.30, but the price may not go that low again for a while. I think a position at 6 or above, with a stop below 5, would be a good entry with a good risk reward.
