The Bollinger Band Screen

I've received several emails expressing interesting the Bollinger Band Screen I showed earlier so later after market I'll touch on some basics.

Looking at SLV and USO, there are some developments...

 SLV -much like the SPY I showed you earlier, you can see resistance at the mid range of the blue channel, SLV has crossed above that resistance zone, so this is a small observation, but we make a bunch of small observations and when they start pointing in a particular direction, we start to form high probability trades.

USO also was finding resistance n the middle of the range of the blue BB, it's now in the process of crossing above.

Here are the settings for the different BB's on the chart...
Blue: 20 period/20 width
Green 20 period / 30 width
Yellow 20 period/ 40 width
Red 20 period/ 50 width
The white moving average is a simple 20 bar.
