Many people asked me how to spot the exact moment of Breakout by Bollinger Band........?? ok let me explain what I do......
When the market becomes slow, Bollinger Band makes a narrow range, after that a break out may happen at any moment ..to catch the exact point of breakout one should draw simple support and resistance line and check the chart (in 'line mode' rather than in 'candle mode' since the line mode is based on the close signal ).
Close signal is the most important thing specially when you want to interpret the signals with Bollinger Bands and predict the market. Let’s shift to line chart and see how it looks like: The price line goes up, touches and rides the Bollinger Upper Band. This means the price has broken above the range, and now we have an uptrend.
