Updated BOS mark-out (by Lumiere)
Advanced BOS Detection with Strict Swing Confirmation
This indicator implements BOS detection with several unique features:
🔹 Dual-Candle Swing Validation - Unlike most BOS indicators that use single candle swings, this uses a two-candle confirmation for swing highs/lows, analyzing both the candle wicks and body transitions.
🔹 Directional Lock System - Implements a state machine that prevents duplicate signals until an opposite-direction BOS occurs, reducing noise.
🔹 Precision Wick Analysis - Compares wicks between the reversal candle and confirmation candle to identify the true swing point.
🔹 Real-Time Update & Live Market Adaptation – The indicator continuously monitors price action and instantly updates BOS signals as new candles form, ensuring you never miss a BOS.
How It Differs From Other BOS Indicators:
Usage Examples:
🟦 Bullish BOS:
A green candle closes, followed by a red candle. This will be the new high, and if the next candle closes above the highest wick of those two, it will be a BOS (only if we had a bearish BOS before)
🟥 Bearish BOS:
A red candle closes, followed by a green candle. This will be the new low, and if the next candle closes below the lowest wick of those two, it will be a BOS (only if we had a Bullish BOS before)

How It Differs From Other BOS Indicators:
- Most public BOS indicators use simple HH/HL or LH/LL detection.
- Many don't implement the directional locking mechanism.
- Few use the two-candle wick comparison approach.
- Wick-Based Precision uses the extreme wicks of two candles (not just the body).
- Strict Confirmation requires a close beyond the swing point (no "wick breaks" counted).
Usage Examples:
🟦 Bullish BOS:
A green candle closes, followed by a red candle. This will be the new high, and if the next candle closes above the highest wick of those two, it will be a BOS (only if we had a bearish BOS before)
🟥 Bearish BOS:
A red candle closes, followed by a green candle. This will be the new low, and if the next candle closes below the lowest wick of those two, it will be a BOS (only if we had a Bullish BOS before)
Release Notes
Mini Update📢✔️Line‑Style input for BOS lines: Solid, Dashed, Dotted
✔️Line-width input for BOS lines: 1–5
New feature:
✔️Next Potential BOS
Only appears in the allowed direction, so after a Bullish BOS only the next potential Bearish line shows next, and vice versa.
Only marks out in closed candles.
The right endpoint of the active Potential line is updated each bar, so it only reaches to the current candle and not infinitely.
When a real BOS fires in that direction, the corresponding Potential line is deleted and replaced by the real BOS line.
(You can see on the chart that there’s a small black line at the top, indicating the Next Potential Bullish BOS)
✔️Independent color inputs
✔️Independent width inputs
Release Notes
Mini Update📢✔️Next Potential BOS now has style options
✔️There's just one button to toggle the “Show Next BOS” feature on and off
Release Notes
Mini Update📢New feature:
✔️Alert function
The script has two alert conditions: Bullish BOS and Bearish BOS. They fire when price closes beyond the last high/low. In other words, when you get a BOS, you get an alert.
To get the alert, do the same as you normally do. Just click on the + sign on your chart and then click on ''Add an alert on BOS mark-out''
