What cumulative volume delta tries to show
The indicator examines executed buying and selling activity.

DailyForex discusses cumulative volume delta as a way to examine pressure behind market moves. Rather than deriving every signal solely from a series of prices, the indicator accumulates a difference between buying-initiated and selling-initiated volume. The resulting series can be compared with the direction of the traded price.
The source explores how stronger participation or a divergence between volume pressure and price can change a chart interpretation. This adds a different type of evidence to a price-only study, but a divergence is not a scheduled reversal or an instruction that works independently of context.
The discussion is best understood as an introduction to order-flow analysis. The quality and scope of the available transaction data matter, especially when comparing centralised exchange data with fragmented markets. No indicator is presented here as eliminating trading risk or guaranteeing advance knowledge of the next price movement.
