CG, a look at weekly chart says looking shaky, as it has broken Support and not yet regained it. MACD < 0 signals selling pressure and the respite of MACDh> 0 providing short term buying pressure looks like it may be rolling over. The end of week Close will provide an indication of where to next. A Close > Jul15 Low of $2.12 will be a win for the bulls after last weeks push thru and C < Support.
As for Stops; there's an art to setting, and depends on time frame of chart you are looking at.
Last week's low 2.06 would be a line in the sand for me. A break of this and she could go lower.
