Stopping Volume vs No Demand: Distinguishing Exhaustion from Absence

One signals aggressive arrival. The other signals absence. Mixing them up turns a reversal long into a fade short.

Stopping Volume and No Demand both describe weakness, but at opposite ends of the effort spectrum. Confusing them is the most common VSA error after the first month of study, because both can print a narrow bar near a swing extreme.

The volume signature test

The single most reliable separator is the volume ratio against the 30-bar average (V30):

• Stopping Volume: volume > 1.75 × V30. Professionals are present and transacting heavily.
• No Demand: volume < 0.7 × V30. Professionals have stepped away.

A narrow bar near a low with 0.5 × V30 is not stopping volume — it is no supply. A narrow bar near a low with 2.2 × V30 and a close in the upper half is stopping volume.

Close position and wick

Follow-through rules

Stopping Volume confirmation: within one to two bars, an up bar closing above 0.7 with volume above V30 validates the reversal. If the next bar makes a new low on volume > 1.5 × V30, the stopping volume failed — professionals were still distributing, and you must not average down.

No Demand confirmation: no immediate follow-through is required because No Demand is a signal to avoid a long, not to short. The valid short trigger is the bar after No Demand breaking its low on volume > V30.

Worked example

A forex pair falls for eight daily bars into support. Bar nine: wide spread down, volume 2.1 × V30, long lower wick, close at 0.65. Stopping Volume. Wait for bar ten: if it closes up on volume above V30, enter long at the close, stop 1 × ATR below bar nine's low, target the prior swing high. Risk-reward ≈ 1:2.4.

The same pair in an uptrend, pulling back for three bars. Bar four: narrow spread, volume 0.55 × V30, close at 0.6. No Demand. Do not buy the pullback. Only short if the next bar breaks bar four's low on rising volume.

The trap that links them

A failed Stopping Volume often produces a No Demand bar one session later as price bounces weakly. Traders who shorted the failed stopping volume get caught. The rule: after a failed stopping volume, stand aside for three bars before taking the next signal.

Read the volume ratio first, the close second, the wick third. The label falls out of those three numbers.
