PS Got the BB width method from Market Geeks (free). It just says that if a stock is sticking very close to its 20 day SMA, for any longish length of time, then a break up or down away from it becomes more likely. Doesn't follow from the Random Walk hypothesis, but if you think that stocks are moved by news, or even long periods of no news, then that is a form of reasoning for the indicator. Didn't think that SLR would come out with bad news (lower grade, mine difficulties, etc) or the pog go down much, so thought a move up more likely. Could equally have gone the other way perhaps?
