Price correction: pullback or reversal?

A correction moves against a prior leg or reference trend. Depth and duration can be observed; resumption of the trend is not implied.

In plain language — A correction moves against the selected reference move. It may be a pause inside a trend, but that is only known if the later structure holds.

Correction does not mean the earlier price was wrong or that direction will certainly resume. It describes movement against a prior leg or selected trend. Without that reference, the same leg may be a correction on one chart and a trend on another.

The retracement is observable; continuation, range, and reversal remain separate outcomes.

Define the reference move

Mark the start and end of the prior leg, then measure the counter-move. Depth, duration, and overlap describe the correction without deciding its outcome. “A 40% correction” is incomplete unless the segment and price convention are clear.

The term pullback is often used for a return towards a level or after a breakout. Everyday usage overlaps, so technical writing should state its convention.

Correction or reversal

The difference cannot be known in advance with certainty. One process may keep the structure intact until a selected pivot breaks; another may require a close, elapsed time, or a new high-low sequence. These are rules, not natural properties of a chart.

Example — After a rise from 100 to 120, price falls to 112. The retracement is 8 points against a 20-point leg. That measurement is known; pause or reversal depends on the rule and later data.

Operational use and limits

A correction may offer a different distance to invalidation from chasing the impulse. It is not an automatic entry: it can deepen, last longer, or become a new structure. Lower speed, overlapping bars, and lower volume are possible traits, not universal requirements.

A Fibonacci percentage does not by itself turn a retracement into support or confirmation. Entry, exit, and position size remain separate rules.

Advanced: depth and knowability

A simple depth measure compares the counter-move with the prior leg. It changes when using wicks, closes, or adjusted prices, and gaps can change it without intermediate trading.

In a backtest, record when each extreme becomes knowable. If pivot confirmation requires future bars, using it earlier introduces unavailable information. Evaluation must keep that delay and execution costs.
