From an order-book perspective: $SNDKB loses the 1,100 level
There are often a lot of resting orders around price levels like this, and big players love to make their move there: they may push the price below the level to trigger stop-losses, then pull it back up, or follow through on the break and drive it lower. To tell the difference, watch which way the large orders above and below the level are leaning.

Volatility is high, so manage your position size carefully.
