Valid BOS Pullback
By LuxAlgoOct 7, 2026
The Valid BOS Pullback indicator is a sophisticated structural analysis tool designed to identify and validate break-of-structure (BOS) events with greater precision. By requiring a specific retest of the original swing level before confirming the continuation of a trend, this indicator effectively filters out noise and potential false breakouts. It provides traders with a systematic approach to identifying high-probability setups, ensuring that price action demonstrates a genuine commitment to the newly established structural range before a signal is generated.
How to Trade the Valid BOS Pullback?
The indicator operates by monitoring price as it moves beyond previous structural highs or lows. To trade with it effectively, follow the progression of each setup:
- Identification: The indicator automatically detects swing points based on your settings. When price breaks beyond these levels by a defined distance, a new potential BOS setup is initiated.
- The Retest Phase: A "Valid Pullback" label appears when price returns to touch the original reference level. This is a critical stage, as it confirms that the market is respecting the previous structural boundary.
- Confirmation: Once the retest is successful and the price subsequently breaks through the newly established extreme, the indicator flags the setup as a confirmed BOS. This provides a clear, objective signal that the momentum is likely to continue in the direction of the break.
- Risk Management: Traders can monitor the "developing levels" to gauge the maturity of a trade. If price penetrates the reference level beyond the allowed tolerance, the setup is invalidated, helping to protect against entries into losing momentum.
Valid BOS Pullback Settings
Structure
- Swing left bars: Sets the number of bars required to the left of a pivot to be considered a valid swing point.
- Swing right bars: Defines the number of bars needed to the right to confirm a pivot, ensuring the structural level is significant.
- Structure lookback (bars): Determines the historical window for finding structural highs and lows to be used as potential reference lines.
- Close invalidation tolerance (ticks): Sets the maximum distance price can close beyond the reference level before the setup is discarded as invalid.
- Minimum bars without a retest: Ensures a period of price separation between the initial break and the retest, filtering out immediate, erratic rejections.
- Minimum initial break (ticks): Sets the minimum distance price must close beyond the structural level to qualify the start of a new setup.
- Maximum setup age (bars): Sets the expiration limit for unfinished setups to keep the charts clean.
