put buy limits in at just below 42 in the smallest size you can. Disaster stops I suppose around 39.50 ish but plan to be out well before that.
whats happened here is that the CME/Comex have increased the margin requirement on the silver futures contract (at least I guess, there was talk on friday/thursday). So nothing fundamentally has changed to Silver, nor the dollar, nor the overall demand for silver for industrial purposes.
The only thing that has changed here is structural, and a bunch of contracts are having to be sold by people whether they like it or not. If you think that nothing has changed, then you can fade these moves as a volume/liquidity imbalance albeit on a larger scale.
As for why buying below the lows, well the world and his dog will be looking to fade this move. After the consolidation, you can take a reasonable stab that there will be stop sell orders below the lows from those who are slightly too quick to jump on the bandwagon. Let the market take these guys out, move back into balance and return to the " fair" price of around $48. Take some off at $47 and see how the rest feels.
follow my advice at your peril
but thats the way Id trade it in a geberal sense anyway.
all imho.
