Fibo Box Breakout Indicator: A Range And Five Levels

Written by Dominic Walsh · Published 5 Jun 2026 · Last updated 9 Sep 2026

The fibo box breakout indicator draws the range before the break. A swing high and a swing low inside `SwingLookback` `50` bars form a box. Five fibonacci levels split it, and a close past either edge earns a mark.

This build ships as a compiled .ex4 for MT4 and .ex5 for MT5; the screenshots below come from EURUSD H1.

What the Fibo Box Breakout Indicator draws on the chart

A slate blue rectangle covers the swing range.

Goldenrod lines split it at 0.236, 0.382, 0.5, 0.618 and 0.786.

`Fibo Box BUY` uses arrow 233 and `Fibo Box SELL` uses 234.

`ShowBox` and `ShowFibLevels` switch either layer off.

• Fibo Box BUY: arrow, lime, width 2, arrow code 233
• Fibo Box SELL: arrow, red, width 2, arrow code 234

How the Fibo Box Breakout Indicator calculates its values

Pivots build the box

`PivotStrength` `3` confirms a swing with three bars either side. The code searches `SwingLookback` `50` bars for the highest and lowest of those pivots. Their times set where the box starts and ends.

Five levels split the range

Each level takes the box low and adds a share of the range. The 0.5 line sits in the middle while the rest fall where the ratios put them. All five redraw when the box changes.

A close decides the break

The current close has to sit beyond an edge while the previous one sat inside. Using closes rather than wicks cuts the number of marks, and it also delays each one by a bar.

How to read the signals

The box shows the range that a break has to leave.

Levels inside it are references, and price often stalls near the 0.618 line.

A mark means one closed bar finished outside an edge.

`TopColor` and `BottomColor` separate the two sides at a glance.

Alert channels in this build: popup, push notification, email and sound, one message per closed bar.

`EnableAlerts` covers the break messages and starts true, with `EnablePopup` showing the dialog. The remaining routes wait for you: `EnablePushNotify` for a phone, `EnableEmail` for mail, `EnableSound` for the clip in `SoundFile`. One message per closed bar.

Settings that fit your chart

A fifty-bar search needs a chart that holds a range. EURUSD H1 is the reference chart, where `SwingLookback` `50` covers two days. On M5 the box redraws several times a session. H4 charts hold one box for weeks.

When the Fibo Box Breakout Indicator fails

A three-bar pivot confirms late, so the box updates after the fact.

Closes ignore a wick that pierced an edge and came straight back.

The five levels are drawn references and take no part in the break test.

FAQ

What does SwingLookback 50 search?

Fifty bars of history for the highest and lowest confirmed pivot. Those two set the box. Shorten it and the box tracks recent price closely. Lengthen it and the range stays put through longer stretches of movement.

How strict is PivotStrength at 3?

Mild. A bar only has to beat three neighbours on each side, so plenty of small turns qualify. That keeps the box responsive, at the cost of letting minor swings redefine an edge. Raise it for a steadier box.

Why does Fibo Box BUY need a close?

Because a wick beyond an edge often retreats within the same bar. Waiting for a close filters those out. The trade off is one bar of delay on every mark, and a move that runs hard leaves you further from the edge.

What does ShowFibLevels turn off?

The five goldenrod ratio lines drawn inside the box, at 0.236 through 0.786. Switching it off leaves the rectangle and the arrows in place. Nothing about the break test changes, since the levels never fed it.

Are results guaranteed?

No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the Fibo Box Breakout Indicator as one input. Always backtest before trading live.
