BBDivergence

Description

The BBDivergence is a technical indicator developed by Markos Katsanos; it measures divergence between a security and a related market. Based on Mr. Katsanos’s article “Trading the Loonie”, this indicator’s values are used for recognizing trading signals in the related strategy.

The BBDivergence study estimates the divergence between two instruments using the following algorithm:

  1. The relative position within the Bollinger Bands® is calculated for both primary and secondary symbols.
  2. The divergence is calculated as the percentage difference between these two positions.
  3. The divergence is then analyzed in relation to two predefined levels, usually placed above and below the zero line.

As the author suggests, trading signals might be derived based on the behavior of the divergence plot; these signals are used in the BBDivergence strategy after confirmation by other technical indicators. A buy signal is suggested when the divergence rises above the upper level (set by default at 20%) and then starts declining. Vice versa, it might be interpreted as a sell signal when having fallen below the bottom level (-20% by default), the divergence reverses its direction.
