Bullish divergence is huge on this one, on every new low silver makes on the 4 hour timeframe. Grexit fears should also give gold and silver a push upwards.
Entry: 15.956 S/L: 15.665 (Stops will not be hit instantly, until the price closed below 15.665 for at least 2 candles to avoid stop hunters) T/P: 17.29
A final low may be made pretty soon.... I don't think the correction for silver is done yet, $13 is possible.
