ma1 Bollinger Bands

on Sun Mar 29, 2015 4:50 pm
Bollinger bands are used to measure a market’s volatility. Basically, this little tool tells us whether the market is quiet or whether the market is LOUD! When the market is quiet, the bands contract; and when the market is LOUD, the bands expand. Notice on the chart below that when the price was quiet, the bands were close together, but when the price moved up, the bands spread apart.

That’s all there is to it. Yes, we could go on and bore you by going into the history of the Bollinger band, how it is calculated, the mathematical formulas behind it, and so on and so forth, but we really didn’t feel like typing it all out.

The Bollinger Bounce

One thing you should know about Bollinger Bands is that price tends to return to the middle of the bands. That is the whole idea behind the Bollinger bounce (smart, huh?). If this is the case,then by looking at the chart below, can you tell us where the price might go next?

If you said down, then you are correct! As you can see, the price settled back down towards the middle area of the bands.

That’s all there is to it. What you just saw was a classic Bollinger bounce. The reason these bounces occur is because Bollinger Bands act like mini support and resistance levels. The longer the time frame you are in,the stronger these bands are. Many traders have developed systems that thrive on these bounces, and this strategy is best used when the market is ranging and there is no clear trend.
