X Trend Premium Indicator: Coloured Baseline With ADX Gate

Written by Dominic Walsh · Published 17 Jul 2026 · Last updated 21 Aug 2026

The x trend premium indicator keeps a visible baseline on the chart and marks the crosses that pass a strength test. X Trend Up and X Trend Down colour that baseline by state. X Buy and X Sell only print when the strength reading agrees, so quiet crosses leave no mark.

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

What the X Trend Premium Indicator draws on the chart

X Baseline runs under the state colouring as the reference line.

X Trend Up carries the line while the fast average sits above the slow one.

The other side hands it to X Trend Down instead.

Markers named X Buy and X Sell record the crosses that also clear AdxThreshold.

• X Trend Up: line, lime, width 2
• X Trend Down: line, red, width 2
• X Baseline: line, goldenrod, width 1
• X Buy: arrow, lime, width 2, arrow code 233
• X Sell: arrow, red, width 2, arrow code 234

How the X Trend Premium Indicator calculates its values

Two averages and a state

FastPeriod and SlowPeriod give two exponential averages, read on the current bar and the one before. Their relationship sets the state that colours the baseline.

At 12 and 34 the pair is slower than a scalping cross and faster than a long trend filter, which is what makes the baseline hold its colour through ordinary pullbacks.

The strength gate

A cross alone colours the line but marks nothing. The strength reading over AdxPeriod has to sit above AdxThreshold on the same bar before a marker prints.

At 18.0 that threshold sits below the conventional 20, so it lets through moves that are building rather than only those already established.

Placing the markers

ArrowGapPts sets a fixed gap between a marker and its candle, 15 points by default, which is tight compared with most arrow tools.

The baseline keeps drawing whether or not a marker appeared, so the state and the signal are separate readings.

How to read the signals

Baseline colour is the state, and a marker is a state change that passed the strength test.

A colour change without a marker means the cross happened while strength sat under AdxThreshold.

That gap between colour changes and markers is the most useful thing this tool shows.

A threshold of 18.0 is deliberately permissive, so markers appear earlier than a stricter setting would allow.

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

Alerts cover popup, push, email and sound on a qualifying cross. A bar time check keeps it to one alert per closed bar.

Every X Trend Premium Indicator input

Core settings

Setting	What it does	Default
FastPeriod	Fast EMA period. FastPeriod is the quick average length. It defaults to 12.	12
SlowPeriod	Slow EMA period. SlowPeriod is the slow one at 34.	34
AdxPeriod	ADX / DI period. AdxPeriod is the strength lookback, 14 by default.	14
AdxThreshold	Minimum ADX to confirm a trending market. AdxThreshold is the minimum strength a cross needs before a marker prints. It defaults to 18.0, and raising it towards 25 cuts the marker count sharply.	18.0

Display settings

Setting	What it does	Default
ArrowGapPts	Arrow offset from candle (points). ArrowGapPts is the cosmetic gap between a marker and its candle, 15 points by default.	15

Settings that fit your chart

The screenshot uses EURUSD H1. A 12 and 34 pair on H1 holds its state across a session, which is what a baseline is for. On H4 and daily the colour changes become rare events. On M5 the pair crosses often enough that AdxThreshold does nearly all the filtering, so raising it there is the usual adjustment.

When the X Trend Premium Indicator fails

A permissive threshold lets weak moves through. At 18.0 some marked crosses happen in conditions a stricter setting would reject.

The strength reading rises in either direction, so it confirms that something is moving without confirming which way.

Both readings lag. The baseline changes colour after the cross, and the strength reading builds after the move starts.

A 15 point gap is tight, so on a volatile symbol the markers can sit inside the candle wicks.

FAQ

Why does the X Baseline change colour without a marker?

Because the two events are separate. Colour follows the relationship between the two averages, which changes on every cross. A marker also needs the strength reading above AdxThreshold, so a cross during quiet conditions colours the line and prints nothing.

Is AdxThreshold 18.0 too low?

It is deliberately permissive. Twenty is the more conventional floor, and eighteen lets through moves that are still building. That trade is earlier markers against more of them failing. Raising it to 25 gives far fewer and stronger ones.

What does the gap between FastPeriod and SlowPeriod control?

How often the state changes. Twelve and thirty four sit far enough apart that ordinary pullbacks do not flip the baseline, and close enough that a genuine turn registers within a few bars. Narrowing the gap produces many more crosses.

Should I widen ArrowGapPts from 15?

On a volatile symbol, yes. Fifteen points is tight, and on an instrument with long wicks the markers can end up sitting inside them. Widening it moves the marker clear of the candle without changing anything about when a signal fires.

Are results guaranteed?

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