The playbook at a glance

Market conditions: Frozen prior-session range; study of a failed downside breakout.
Setup & entry trigger: Sweep below range low, completed reclaim and next completed confirmation; entry at following eligible open.
When the idea fails: Setup low minus the predeclared buffer.
Position sizing: Use the initial price distance plus friction and all portfolio/cash constraints.
Exit policy: Initial invalidation, frozen range midpoint or defined session end.
When to skip: Reward/risk hurdle fails, a disqualifying close occurs, prohibited event window, or one attempt already used.

These rules are unvalidated research candidates, not a claim of positive expectancy. Parameter choices are illustrative. Test costs, gaps and funding before interpreting a result.

A price beyond support does not owe you a bounce #

The hypothesis is that a move below a previously defined range can fail to gain acceptance and return inside it. This is different from buying every new low. Define the range before the event and require a completed reclaim; otherwise the trader can keep naming lower prices as a better opportunity.

For an illustrative hourly paper study, use the high and low of the previous trading session as frozen boundaries. Require the range width to exceed four times the assumed round-trip friction per unit; this is only a research liquidity screen, not a universal threshold. Use one declared session calendar and timezone.

Separate a sweep from a confirmed reclaim #

The setup bar trades below the previous-session low but closes back above it. The next completed hourly bar must close above the setup bar’s high without first triggering a disqualifying close below the range low. After that confirmation, enter at the following eligible bar’s open within the entry-distance allowance.

You are waiting for observable conditions, so the entry can be worse than the attractive low shown on a later screenshot. Record that cost of confirmation. Do not credit the strategy with an entry at the sweep low when the reclaim was not yet knowable.

Define the asymmetric-looking trade honestly #

Set initial invalidation below the setup low using a frozen buffer. Use a planned objective at the midpoint of the previous session’s range only if the entry-to-objective distance is at least 1.5 times initial price risk in this version. Costs reduce the net reward-to-risk. If that hurdle fails, skip rather than force a closer stop.

The attractive geometry is not evidence of high win probability. Persistent trends can repeatedly sweep a level before continuing lower. One attempt is allowed per range in this candidate. Repeated entries after a stop would be a distinct method with a different losing-tail distribution.

Include a clock and a price-invalidating event #

Exit at initial invalidation, range midpoint or the end of the specified session. A time exit must use a realistically available closing execution assumption. If the method trades a contract with a different settlement session, adapt and register the schedule rather than copying an equity-market close.

Exclude predefined major-release windows from this particular candidate, and keep exclusions consistent during testing. A failure that occurs around news is still a valid loss if the event was not excluded beforehand. A retrospective news explanation cannot remove it from the sample.

Compare it with doing nothing #

Investigate how often the range is reclaimed but fails to reach the midpoint before the session ends, whether gaps bypass the invalidation and how much of the apparent reward is consumed by spreads. Separate the backtest’s early and late parts and compare the candidate with a simple no-trade baseline or an appropriately specified exposure benchmark.

A method can look appealing because it avoids many sessions, but a small number of exceptional rebounds may dominate. Report concentration, not just average R. Retain every qualifying failed reclaim; otherwise the research is a collection of examples rather than an evaluation.

Hypothetical worked example

A fictional reclaim that qualifies—and one that does not

Previous-session low is 200 and high is 220, so the midpoint is 210. A sweep reaches 198 and closes at 202. A later qualifying entry is 203 and buffered invalidation is 197: price risk 6 and reward to midpoint 7. The ratio 7/6 ≈ 1.17 fails this candidate’s 1.5 minimum, so no trade occurs.

If another independently qualifying range gives entry 202, invalidation 198 and midpoint 210, price reward/risk is 8/4 = 2. With friction of 0.5 per unit, the conservative planned net reward is 7.5 and loss allowance 4.5. Neither geometry establishes the win probability or limits a gap loss.

Common mistakes

Buying the sweep before the reclaim exists.
Tightening the invalidation just to pass the reward/risk hurdle.
Taking repeated attempts without including them in the test.

Check your understanding

A visually attractive reclaim fails the predeclared reward/risk hurdle. What does this version do?

Make this chapter useful

Can you defend the reasoning?

Before moving on, answer the self-check in your own words and write why each alternative fails. Use the worked example to test that explanation. Then apply it in the module research task; keep the assumptions and the evidence that could change your answer.
