What Is Volume Delta?

Volume Delta measures the difference between buying and selling volume:

Volume Delta = Buy Volume − Sell Volume

+334

Buying volume exceeded selling by 334 contracts

−210

Selling volume exceeded buying by 210 contracts

≈ 0

Relatively balanced buying and selling activity

Volume Delta can confirm price movement, identify weak participation, filter trading signals, and reveal situations where price and order flow disagree.

Three Delta Calculation Modes

Recommended
UpDownTick RealVolume

Uptick = buying, downtick = selling, same price retains previous direction. Uses real trade volume. Works on historical and real-time data without Tick Replay via an internal secondary tick series. Best for futures and stocks.

UpDownTick UnitVolume

Measures activity by tick count instead of real volume. Each uptick adds one buying unit, each downtick one selling unit. Useful for CFDs, indices, or forex feeds where centralized real volume is unavailable.

BidAsk RealVolume

Classifies live trades using the current Bid and Ask. Trades at or above Ask = buying; at or below Bid = selling. Historical BidAsk delta requires historical Bid/Ask tick data from the provider. Falls back to Up/Down Tick when unavailable.

Custom Delta Strength Thresholds

Seven strength categories, each with its own customizable color and threshold. Defaults shown below — adjust based on instrument and timeframe.

Positive Strong
above +150

Positive Moderate
+50 to +150

Positive Weak
0 to +50

Neutral
near zero

Negative Weak
−50 to 0

Negative Moderate
−150 to −50

Negative Strong
below −150

Thresholds for MNQ will differ significantly from NQ, ES, CL, or individual stocks. Adjust after observing normal delta distribution for your instrument.
