From Norcini:

Let's start with the star of the complex of late, and that is silver. One look at the chart says it all. Silver can now be officially labeled as having rallied over 20% off its recent low. For definition purposes, that is considered a bull market. It does not mean it is going to the moon; it does mean that the bear market is over barring any subsequent sharp price collapse in the metal. You will also notice that on the Directional Movement Indicator the ADX is now beginning to turn higher. It was rising strongly since early February indicating the presence of a sustained DOWNTREND. The line then turned down for good in late June/early July indicating that the downtrend was halted. That was followed by a period of sideways trade or consolidation. Now the ADX line is rising indicating that silver is in the incipient stages of a trending move, this time however, to the upside. As you can also see that is confirmed by the fact that the +DI (blue line) has now crossed solidly above the -DI (red line) which is moving lower.
