Silver Commodities Trading/Investing

I have come to appreciate the benefits of commodities trading or investing. Gone are the days when you would buy physical commodities. Using the CMC Plc trading platform (www.cmcplc.com) is one option, but there are others. eg. Saxobank.

By far the best commodity to trade at the moment is silver, though you can always short the other commodities. The only commodities CMC trade are:

1. Spot gold & silver
2. Platinum & palladium futures

The strategy is to trade these commodities off a moving average - I use MAV(simple, 40), MAV(exp, 30). When it pulls back to the MAV(40), I am inclined to take a position. I see silver going to $US20/oz.
