Direct answer
A worked example of Role Reversal is a scenario where a price level that previously behaved like “support” later behaves like “resistance,” or where a previous “resistance” level later behaves like “support.” The key point is not prediction; it is a descriptive way to test whether market reactions at a level change after it is broken.
Mechanism or definition
In basic support and resistance language:
- Support is a price area where price has often stopped falling (buyers previously responded).
- Resistance is a price area where price has often stopped rising (sellers previously responded).
- Role Reversal is the observation that once a support area is clearly broken, that same area (or nearby band) may later act as resistance; similarly, once resistance is clearly broken, it may later act as support.
To keep a “worked example” falsifiable, you need explicit assumptions:
- What counts as “support/resistance” (a prior swing high/low, or a small price band)?
- What counts as a “break” (for example, closing beyond the level by a certain amount)?
- What counts as “later interaction” (for example, a later approach that fails to cross back)?
Evidence or example (with explicit assumptions)
Here is one numerical scenario. It does not use live prices; all numbers are assumptions.
Assumptions for the example
- Consider a single price level at 100.00.
- Assume the market previously reacted at 100.00 twice:
- Day A: price falls to 100.00 and rebounds.
- Day B: price again falls to 100.00 and rebounds. Under this assumption, 100.00 is acting as support.
- Define a “break” as: a close below 100.00.
- Define “role reversal test” as: after the break, price later reaches 100.00 again but closes below 100.00 (a failure to sustain above 100.00).
Scenario timeline
-
Before the break
- Day A close: 101.20
- Day A low: 100.00
- Day B close: 101.00
- Day B low: 100.00
- Interpretation (based on the assumptions): 100.00 is support.
-
Break of support
- Day C close: 99.70 (below 100.00)
- Interpretation: support has been broken.
-
Later interaction and reversal attempt
- Day D low reaches: 100.00
- Day D close: 99.60 (back below 100.00)
- Interpretation: price returned to 100.00 but did not hold above it; under the assumptions, 100.00 is now acting like resistance.
What you can independently verify Using only the defined rules above (support reactions at 100.00, a close below as the break, and a later return that fails to hold), you can check whether the sequence matches the description of Role Reversal.
Limitations and risks (at least one failure mode)
Role Reversal is descriptive, and multiple issues can make a “worked” example fail in practice:
- False breaks and reclaims: The market may dip below a level briefly, then quickly return and hold it. In that case, the “break” rule you used may have been too loose.
- Ambiguity of the level: Real markets form bands rather than single exact prices. If you choose 100.00 as a single point while real reactions occur across a wider area, your test may look inconsistent.
- Changing market structure: Even if a level flips roles once, later conditions can shift so reactions no longer occur at the same area.
- Execution and costs (general, not using any specific broker): If you translate the idea into actions, spreads, commissions, and slippage can change outcomes. This does not invalidate the concept, but it limits how you interpret historical behavior.
Verification or next question
To verify Role Reversal yourself, repeat the same logic with clear, pre-written rules:
- Pick a candidate level (or band) from prior price reactions.
- State your break condition (e.g., “close beyond” relative to that band).
- State your test condition (e.g., “later approach that fails to close beyond again”). Then compare different time windows to see whether the “reversal” depends on the lookback length.
If you want, share your own chosen support/resistance level definition and break rule, and you can test whether your criteria actually produce a Role Reversal sequence without relying on prediction.
