The trigger close: body-close confirmation in the Fractal Model

The trigger close is the mechanical confirmation event of the Fractal Model. It does not predict reversals; it timestamps them: price has body-closed through a defined line after moving the other way.

Other vocabularies call this a body-close confirmation. This library says the trigger close.

The definition

The trigger line is the open of the last opposing chart-timeframe run into the sweep:

• Bullish trigger: price was moving lower into the sweep of a low; the open of the final bearish run is the line; a candle body-closes above it.
• Bearish trigger: the mirror. The final bullish run's open, body close below.

A wick through the line is never the event; only the close confirms. That separates three states: armed (candidate waiting), triggered (body closed through), and absent (window ended without the event). On the chart the line is dashed while armed and solid once triggered, with the callouts trigger · price and triggered · price.

The trigger close must land by the close of the D3 window, the model candle after the sweep candle. A trigger close in that window confirms the setup while D3 is forming. A later close is too late. A deeper sweep moves the candidate and its line to the new extreme. A candidate that never triggers expires quietly.

The trigger close is confirmation, not context

You can find a trigger close on any chart if you look long enough. It matters only inside the operating order: directional context first, then model-timeframe structure at a qualified location, and only then the trigger close on the chart timeframe. Without location, a trigger close is only a lower-timeframe event.

Use the correct pair

These are FMP+'s core Automatic pairs; 1 second/1 minute and 15 seconds/5 minutes are deliberate fast-chart extensions. Published six-pair ladders elsewhere end with 4 hour/1 week and do not include FMP+'s higher-chart or fast-chart extensions, so the tables are not identical.

A 4-hour D2 Sweep is confirmed by the first closed 15-minute body through the trigger line, not by where the 4-hour candle eventually closes. The event can arrive before the model candle closes: the first confirmed chart close carrying both the close back inside and the trigger close is an early read. FMP+ fires its alert at once and draws the read at once when no setup is active; against an active setup it calls the read out at the right edge. The model-timeframe close installs the structural record. An early read describes timing, never a relaxed rule.

Workflow

1. Model timeframe first. Active candle, sweep, qualified location. If any is missing, stop.
2. Direction before dropping down. The model-timeframe sequence defines bullish or bearish; color does not.
3. The defined pair only. Not whichever chart looks cleanest.
4. Mark the trigger line. The final opposing run's open; do not move it as candles print. Only a deeper sweep moves it.
5. Wait for the closed body. Everything else is armed, not triggered.
6. Keep ownership. Once a reversal is confirmed, continuation advances D3 and D4; it does not mint a new rolling D2 Sweep every bar. See D3 Expansion and D4 Continuation.

Common mistakes

• Calling every close a reversal. The model-timeframe geometry and location still gate it.
• Using a wick instead of the body close.
• Letting the model-timeframe close rewrite the chart-timeframe event.
• Moving the trigger line until a signal appears.
• Treating a zone touch as entry confirmation. Location and confirmation are different jobs.

FAQ

Is the trigger close the same as a break of structure?

No. The trigger close is specifically a body close through the final opposing run's open. Other structure concepts use different reference points; do not blend definitions.

Can the trigger close confirm before the model-timeframe candle closes?

Yes. That is the early read: real confirmation on the chart timeframe, installed at the model boundary.

Does a trigger close guarantee continuation?

No. It confirms a historical close through a line. Context, invalidation, and risk remain yours.
