Support and Resistance Zone Indicator for MT4 and MT5

Written by Dominic Walsh · Published 10 Jul 2026 · Last updated 24 Sep 2026

A single line almost never holds to the pip. The support and resistance zone indicator allows for that by drawing each swing as a band whose height tracks the market’s own range. It then marks the bar that tests a band and gets rejected.

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

Platforms	MT4 (.ex4) + MT5 (.ex5)
Chart window	Main price chart
Plots	2: SR Zone Buy, SR Zone Sell
Alerts	popup, push notification, email, sound
Inputs	15

Plot by plot

Zone rectangles plus two marks.

`ResZoneColor` `clrTomato` fills resistance bands.

`SupZoneColor` `clrDodgerBlue` fills support bands.

`SR Zone Buy` prints lime at width 2.

`SR Zone Sell` prints red at the same width.

`MaxLevels` `6` caps how many bands stay drawn.

• SR Zone Buy: arrow, lime, width 2, arrow code 233
• SR Zone Sell: arrow, red, width 2, arrow code 234

The method

Finding a swing

`SwingBars` `4` bars either side must fail to beat a candidate. Four is moderate, so the swings behind each band are real turns.

Sizing the band

`AtrPeriod` `14` gives a range figure. `ZoneWidthATR` `0.55` sets half the band’s height, so quiet markets draw thin bands and busy ones draw thick bands.

The rejection mark

A bar has to reach into a band and turn away from it. `CooldownBars` `5` then keeps the next same-side mark at least five bars off.

What you act on

Blue bands sit under price, red bands above it.

Thicker bands mean the market has been moving more.

A lime mark is a rejection at support.

A red mark is a rejection at resistance.

Only the six most recent bands remain.

Swings confirm four bars late.

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

A rejection at a band is what the note reports: support for a buy, resistance for a sell. `EnableAlerts` is the master switch and a popup carries it; the phone, email and desktop routes behind `SoundFile` stay closed.

Picking a chart for it

Four-bar swings with range-sized bands work across most liquid charts. EURUSD H1 is the reference chart, where a band often holds for days. On M5 the bands shift quickly. On H4 each one reflects a week of structure.

Known limits

A rejection can turn into a break a bar later.

Bands widen after volatility, not before it.

Six bands can miss an older level that still matters.

Every swing confirms four bars after the fact.

FAQ

Why does ZoneWidthATR 0.55 size each band?

So the band follows the market’s pace. Half the band’s height equals just over half the current range, which keeps bands thin in quiet trade and thick when price moves hard.

What makes an SR Zone Buy mark print?

A bar reaching into a support band and turning back up from it. The note describes it as a rejection at support, and the mark sits under that bar.

Why wait CooldownBars 5 after a rejection?

A string of marks while price sits inside the same band. After one rejection, the next same-side mark has to wait at least five bars.

Why keep only MaxLevels 6 bands?

Recent structure matters most, and a chart full of old bands is hard to read. Six covers the nearby levels without burying the candles, and you can raise it on a slow chart.

Are results guaranteed?

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