Aquila Reale BOS CHoCH + Zone🦅 Aquila Reale BOS CHoCH + Zone
A simple, lightweight tool for traders who follow Smart Money Concepts (SMC) or price action. It marks market structure shifts — Break of Structure (BoS) and Change of Character (CHoCH) — and highlights untouched Fair Value Gaps as liquidity zones.
What it does
The script tracks swing highs and lows to detect when structure breaks. A BoS confirms trend continuation; a CHoCH flags a possible reversal. Each event is drawn directly on the chart with a clean bracket and label, using the structure color you choose.
It also plots liquidity zones from unmitigated Fair Value Gaps (the imbalance left when price moves away fast without filling the gap). These yellow areas are, in my own trading, one of the most useful parts of the tool if you work with SMC or price action — they show where price may return to rebalance before continuing.
Built-in alerts — and why they matter
This is the part I really want to highlight. The script comes with ready-to-use alerts for every structure event:
CHoCH LONG / CHoCH SHORT (possible reversals)
BoS LONG / BoS SHORT (continuation)
If you trade across multiple assets, you simply cannot watch every chart at once — not on your own. The alerts let you set the indicator on all the instruments you follow and get notified the moment structure breaks, instead of staring at screens all day. For a solo trader covering several markets, this is what makes the whole thing actually usable. Set them once per asset and let them do the watching for you.
Swing Lookback presets
Detection sensitivity depends on a Swing Lookback value. To keep things easy I've added presets per timeframe:
Auto — picks the lookback automatically based on the chart timeframe
Daily (60), 4H (30), 1H (15), 15m (8), 5m (5), Scalping 1–3m (2)
Manual — set your own value, very simple
Presets are a starting point, not gospel. It's always better to check the result on your own chart and adjust the lookback until the structure marked matches what you actually see. Different instruments and conditions behave differently.
Other settings
Minimum zone width filter (× ATR) to ignore tiny, noisy gaps
Choose whether a zone is removed on partial touch (wick) or only when fully crossed
Option to never delete zones, if you prefer the full history
Max structures on screen — keeps the chart clean and works smoothly on every timeframe, from Daily down to the lowest scalping TFs
Optional label showing the active lookback value
How I use it
I follow SMC / price action: I wait for a CHoCH to signal a potential shift, then look for price to react at an untouched zone before taking a setup. Structure plus liquidity, plus alerts so I never miss it on the other charts.
