Watch RSI for 20 on 15 min chart.

Plug will start gaining very soon. It's time to look for entry points. RSI is one indicator that works well with volatile stocks such as plug.

Strategy - buy when RSI on 15 min chart goes below 20 (there's usually a little bit of lag in price)

My guess is buy at $5.50, but keep your eye on the indicator.
