Example and strategy

Bollinger Squeeze Basic Indicator Example MetaTrader Chart
The indicator uses the momentum to measure the trend's strength and direction:

Rising momentum above the zero line (uptrend) is marked with darker green bars.
Falling momentum above the zero line (also uptrend) is marked with lighter green bars.
Rising momentum below the zero line (downtrend) is marked with darker red bars.
Falling momentum below the zero line (also downtrend) is marked with lighter red bars.

Additionally, Bollinger Squeeze Basic offers an interesting volatility measure built into the main histogram.
The range of blue and red squares on the zero line indicate the current relationship between the Bollinger bands and the Keltner channel:

If the squares are red, the Bollinger bands are outside the Keltner channel, which suggests that exchange rate is trending strongly.
If the squares are blue, the Bollinger bands are inside the Keltner channel, which suggests a flat sideways market.

The main idea behind this indicator is to establish trading ranges
during the non-trending phase of the market (blue squares) to enter on a breakout and
a switch to red squares (trending phase).
The histogram will suggest how strong the current trend is and will tell you when to exit a trade on the trend's weakening.
