What Is Break And Retest?

Direct answer

Break and retest is a commonly used price-action description for a two-step sequence: (1) price moves through a previously meaningful level (the “break”), and then (2) price comes back to that level to test whether it can act as support or resistance (the “retest”). The purpose of the concept is to explain how a market can transition from respecting a level to treating it differently, before any further move.

In forex contexts, people often discuss break-and-retest using chart levels such as prior swing highs/lows, range boundaries, or other visually defined support/resistance. It is not an indicator by itself; it is a way of describing and organizing what you see on the chart.

Mechanism and definition

A practical way to think about break and retest uses a few assumptions and inputs:

A “level” must be defined. This could be the top/bottom of a recent range, a prior swing extreme, or a horizontal support/resistance zone.
“Break” means price goes beyond that level. Depending on the trader’s definition, this can mean a candle close through the level, a wick that pierces it, or how far price travels past it. Those choices matter because they affect how often a move is classified as a break.
“Retest” means price returns toward the broken level after the break. Many users expect the retest to be near the level, but “near” can be subjective (for example, whether you allow a small overshoot).
The interpretation is conditional, not automatic. The retest is often interpreted as the broken level becoming support (if resistance was broken) or resistance (if support was broken). However, the market can also revisit the level without any meaningful change in behavior.

The simple model is: established level → break of that level → price revisits it → possible change in how price reacts at that area.

Evidence or example (chart-based, with explicit assumptions)

Assume you identify a prior resistance level at the top of a recent trading range on a forex chart. Later, price pushes above that level and then falls back.

A break-and-retest reading would classify the event like this:

Break: price crosses above the resistance area (using your chosen rule, such as closes above the level).
Retest: price later trades back down into the same area.
Behavioral expectation: during the retest, price may pause and show signs of rejection near the former resistance.

Important: this is a descriptive checklist, not a prediction. Even when the steps occur visually, outcomes can differ. A retest may fail and price can continue in the original direction without a new behavioral regime.

To verify the idea independently, use only the chart you are looking at:

Mark the level you originally used.
Check whether price later revisited that same area after the break.
Compare retest behavior across multiple instances to see whether the level “holds” in the way your definition requires.

Limitations and risks

Break and retest has material failure modes and sources of disagreement:

False breaks: price may cross a level briefly, then return without any durable shift in market behavior. A retest after a false break can look similar to a “successful” retest if you only focus on the geometry.
Definition sensitivity: results change depending on how you define “level,” “break,” and “retest.” For example, using candle closes versus wicks can move events in or out of the classification.
Ambiguous structure: charts often contain multiple nearby levels (overlapping swings, zones, and ranges). Your choice of which level is “the” level determines what you label as break and what you label as retest.
Costs and execution effects: forex trading involves spreads, commissions (if any), and order execution constraints. Even if the chart behavior is clear, real trading outcomes can differ because fills and timing can occur away from the idealized retest point.
Time-frame dependence: the same price movement can be a break-and-retest on one time frame and a different structure on another. Without stating your chart time frame, the concept is hard to compare across observations.

Because of these limitations, break and retest should be treated as a descriptive framework for analyzing price behavior, not a standalone promise of future direction.
