After it dropped a long way from its morning high, it started stepping up. I drew some ascending s/r lined and the action followed precisely. I bought when it was about to cross VWAP but it stepped down, but then popped back through the support lines and I sold when there was a huge seller at 1.90, even though I thought it might go higher just to be safe. It hung there for 5 min. then halted up again.
