A giant falling wedge has formed on this one, and I've fitted an (ending) diagonal on the chart. I'd say it still has a bit to go on the downside and the best strategy would be to wait til' the wedge is broken to the upside. I circled the overbought RSI peaks (associated with huge volumes) a reminder that we could see those taken out in the future.
