Demand Index

Demand Index combines price and volume in a special way, so it often serves as a leading indicator of price changes. The Demand index was developed by James Sibbet.

James Sibbet formulated six rules for interpreting the demand index:

  • A divergence between the demand index and prices signals an upcoming price reversal.
  • Extremely high values of the demand index often precede the formation of new price highs (the index is a leading indicator).
  • The combination of a new price high with a lower peak of the demand index usually falls on an important price peak (the index is a synchronous indicator).
  • Crossing of the zero level by the demand index usually occurs after a price trend reversal and serves as its confirmation (the index is a confirming indicator).
  • If the demand index constantly fluctuates around zero, the current price trend has weak potential and will not last long.
  • A significant long-term divergence between prices and the demand index indicates an important market top or bottom.
