And I thought only I had questions like this. The bands can only widen when volatility increases either way. Like a plunge or a sudden jump up. Then both sides balloon out. Coral's strategy is supposed to be a good one but I'm not smart enough to use the strategy. I would think an Option Strangle with 2-3 strikes out of the money on both puts and calls would work well too. With this low volatility and tight range the option prices would reflect that and should be cheap. Then when things go crazy one side is very correct and not only often doubles or triples quickly but the premium expands on them also with option sellers getting a premium for them. In my more adventurist days I used to trade TBond options. I found there are better ways to lose money more slowly than that,lol.... But if you are right you are very very right on them and they can pay off big time. But the chart pattern with the small channel showing tells you the same thing as the Bollinger bands that it's trading in a tight range but can be seen easier relative to previous price action. The centre line on the bands is simply a 20sma.
