Description
From John F. Carter's book "Mastering The Trade". See his
YouTube presentation.
- Contractions like the Bollinger Bands inside the Keltner Bands reflect a market taking a break and consolidating, and is usually seen as a potential leading indicator of subsequent directional movement. A series of contractions may suggest to look for a BB expansion outside the KB which would be an entry signal. The longer the contraction, the stronger the potential breakout.
- The entry should be made in the direction of the momentum. A positive momentum supports a long position, while a negative momentum supports a short position.
- The exit should be made when momentum weakens.
