AbuTrader Expert Advisor Indicator: An ADX-Gated Cross

Written by Dominic Walsh · Published 22 Jul 2026 · Last updated 26 Aug 2026

The abutrader expert advisor indicator places no trades, despite the name. It is a chart indicator that draws two lines and marks a crossing. What makes it worth having is the filter: ADX has to sit at or above `AdxMin` before a cross counts, so range chop produces nothing.

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	4: Fast EMA, Slow EMA, Buy, Sell
Alerts	popup, push notification, email, sound

What the AbuTrader Expert Advisor Indicator draws on the chart

Fast EMA and Slow EMA are the two lines, coloured by `FastColor` and `SlowColor`.

Buy marks a crossing up while the trend filter passes.

Sell marks the crossing down.

An OBJ_LABEL note in the corner repeats the current settings when `ShowNote` is on.

• Fast EMA: line, width 2
• Slow EMA: line, width 2
• Buy: arrow, width 2, arrow code 233
• Sell: arrow, width 2, arrow code 234

How the AbuTrader Expert Advisor Indicator calculates its values

The two averages

iMA supplies exponential averages at `FastEma` `13` and `SlowEma` `34`. Both come from the terminal at direct-value form, so warmup and seeding are handled for you. No hand-rolled recursion appears anywhere in this build.

The trend-strength filter

iADX supplies the main line at `AdxPeriod` `14`. trending needs that reading at or above `AdxMin` `20.0`. A cross with ADX below the level is discarded, which removes most of the crossings a plain pair would show.

Spacing the marks

`MinBarsBetween` `3` keeps consecutive same-side marks apart. `MaxBars` `1500` bounds how much history the scan covers. Both settings exist to keep a long chart readable rather than to change the logic.

How to read the signals

The two lines show whether a cross was even close.

A missing mark at an obvious cross means ADX failed the test.

Raise `AdxMin` toward 25 for a much stricter filter.

Nothing here touches your account, so treat the name as a label only.

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

Alerts run through `EnableAlerts`, which is true out of the box, and `EnablePopup` handles delivery. `EnablePushNotify`, `EnableEmail` and `EnableSound` all begin false. `SoundFile` picks the clip. The check reads the last closed bar once.

Settings that fit your chart

A 13 and 34 pair with a trend filter suits charts where moves last hours. EURUSD H1 is the reference chart, where `SlowEma` at `34` covers a day and a half. On M5 the filter blocks a lot and the marks thin out usefully. On H4 they become rare events.

When the AbuTrader Expert Advisor Indicator fails

The name promises an Expert Advisor and the file is an indicator. Nothing here trades.

ADX lags, so it can confirm a trend that has already run most of its course.

`AdxMin` `20.0` is a low bar, and plenty of ordinary conditions clear it.

FAQ

Does the AbuTrader file place trades?

No. This is a custom indicator, not an Expert Advisor, whatever the file name suggests. The code draws two lines, prints arrows and raises alerts. It sends no orders and touches no account state at all.

What does AdxMin at 20.0 block?

Every cross that happens while the trend-strength reading sits below 20. Those are the crossings that occur in a range, where the two averages tangle. Raising it toward 25 makes the filter noticeably stricter.

Why pair FastEma 13 with SlowEma 34?

Both are Fibonacci numbers and the ratio is roughly one to two and a half, which keeps the lines far enough apart to separate. On EURUSD H1 the slow line covers a day and a half, so a cross means something changed over that span.

What does MinBarsBetween at 3 prevent?

A second same-side mark within three bars of the last one. Crosses often arrive in pairs when the two lines hug each other. The gap keeps one wobble from producing three arrows on the chart.

Are results guaranteed?

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