To trade this safely we really need to know if the next move up is a 3 wave structure or a 5 wave structure.
This prolonged drop seems to indicate that this is a C wave however it could conclude as a 5 wave structure and we can eventually short in at the retrace..
There are concerns now with the bullish counts - if the current drop is a minor 2 wave it has exceeded the 61.8% mark which indicates this should go lower and remove the bullish count.
The initial rally for silver can also be counted as a big ABC retracement .. so we are a little in the twilight zone at the moment waiting for price to tell us which side to trade.
For the safe trade to occur I think patience is required and just wait and let price tell us what to trade. The next wave is the important factor after price has moved past so many supports.
