Constructing a halfway volume map for range resolution

A range after an advance

After a sustained advance, price commonly enters a trading range, and volume together with price action is used to judge whether that range is a pause or a turn.

When volume stays elevated while daily ranges narrow at a higher price, that pairing is treated as distribution and as evidence that a change is approaching rather than that an immediate reversal has already begun.

Comparing volume on advances and declines

Volume-price analysis compares how much trading occurs on advances versus declines, and whether ranges widen or narrow, to decide whether a condition is absorption or exhaustion.

Expanding volume on declines and light volume on intervening rallies is read as seller control. A fresh low that does not expand volume is read as selling failing to follow price lower, which can produce a rebound that is still not treated as a confirmed bottom.

The same price path with different volume can reverse the conclusion. Light volume into the highs plus heavy volume that fails to break a prior low is treated as accumulation, with the working hypothesis that the prior high will later be exceeded.

Using the Wyckoff method

The Wyckoff method reads a range as accumulation or distribution by asking whether large selling is being absorbed at the lows or large buying is being met by supply at the highs.

Distribution is heavy activity at a higher price that contains an advance, treated as supply overpowering demand. Accumulation is heavy activity at a lower price that fails to force a new low, treated as demand absorbing supply.

A rebound caused only by sellers declining to sell at lower prices is treated as weaker than a rebound caused by demand appearing at those prices. Without accumulation at the lows, the rebound is classified as a countertrend rally that should retest the decline low.

A break that leaves buyers from the highest advance unable to exit without a loss is treated as putting those buyers on the defensive against the new direction.

Bisecting the range at the halfway reaction

The halfway reaction measure splits a trading range at its midpoint so volume can be assigned to the upper half or the lower half before judging which boundary is more likely to give way.

In a range, the heaviest volume is treated as marking the side opposite the expected exit. Volume clustered at the top is read as distribution. Volume clustered at the bottom is read as accumulation. An uptrend pause typically shows the heavy volume on the lower side.

A majority of volume in the lower half, with demand fading on rallies toward the upper boundary and volume expanding toward the lower boundary, is read as accumulation preceding a markup.

Writing the one-line hypothesis

Editorial: after volume has been assigned, state a single sentence. Price should leave on the quiet side, the half that did not receive the heavier activity, unless the next heavy bar falsifies the ledger.

That line follows the range reading that the heaviest volume marks the side opposite the expected exit. The next heavy bar is the test of the ledger, not a later rewrite of the range itself.

Warnings versus a completed transfer

Weakening demand is treated as a warning of a downturn but not proof of a top. Distribution is treated as a top. Abating selling is treated as a warning of a rally but not proof of a bottom. Accumulation is treated as a bottom.

Consolidation is a pause in which participation fades on one side of the range without a completed transfer of control. Reversal is a completed transfer of control, marked by distribution at a high or accumulation at a low.
