Hi JTH,
As a relative novice, I wanted to ask about the bollinger bands you have in your chart. When I look at the BBs, I just use the presets, which say 20 2. I assume that means 2 standard deviations above and below the 20 MA, whether it be daily, weekly, or whatever measurement of time I'm using in the chart. In your chart, I notice that it says "260 2.0" What exactly is that? Just asking, because all the BBs I'm looking at with my default settings (weekly, daily, hourly & 30 minute) show the SPX just below the bollinger band. I'm curious to learn more. Thanks!
