Optimize MACD Settings Indicator for MT4 and MT5

Written by Dominic Walsh · Published 22 Jun 2026 · Last updated 9 Sep 2026

Most tools ask you to choose the periods. This one chooses them itself. The optimize macd settings indicator walks a grid of fast, slow and signal combinations, scores each against six hundred bars of history, and then plots whichever set came out on top.

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	Separate window
Plots	6: MACD (best), Signal, ZeroLine, BUY, SELL, BiasMarker
Alerts	popup, push notification, email, sound
Inputs	15

What the Optimize Macd Settings Indicator draws on the chart

Six plots below the price chart.

`MACD (best)` fills dodger blue columns.

`Signal` runs orange at width 2.

`ZeroLine` runs silver across the middle.

A lime `BUY` and a red `SELL` mark the crossings.

`BiasMarker` runs gold where the main line leads.

• MACD (best): histogram, dodger blue, width 2
• Signal: line, orange, width 2
• ZeroLine: line, silver
• BUY: arrow, lime, width 2, arrow code 233
• SELL: arrow, red, width 2, arrow code 234
• BiasMarker: line, gold

How the Optimize Macd Settings Indicator calculates its values

The grid

Six inputs bound it. `FastMin` `8` to `FastMax` `16`, `SlowMin` `21` to `SlowMax` `30`, and the signal range, all walked in `SweepStep` `2` increments.

Scoring each set

`SweepWindow` `600` bars decide it. The code builds every combination over that history, scores each one, and plots whichever scored highest.

The separation filter

`SignalMinExpand` `0.00003` of price sets a floor. Where the two lines barely part, no mark prints, which strips out the weakest crossings.

How to read the signals

The plotted periods come from the sweep, not from you.

They can change as the window rolls forward.

A wider grid costs more time on every rebuild.

The gold marker shows where the main line leads.

The separation floor scales with price.

Six hundred bars is the whole basis of the choice.

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

`EnableAlerts` opens the group and arrives on with three of its members: `EnablePopup`, `EnablePushNotify` for the mobile terminal and `EnableSound`, which plays whatever `SoundFile` names. Only `EnableEmail` waits, and crossings report once a bar.

Settings that fit your chart

Six hundred bars is what the choice rests on, so pick a chart where that is a meaningful stretch. EURUSD H1 is the reference chart. That covers about a month there. On M5 it is two days. On H4 it reaches back four months.

When the Optimize Macd Settings Indicator fails

Periods chosen on past bars need not suit the next ones.

A rolling window means the chosen set can change under you.

Scoring a grid on every rebuild costs real time.

Six hundred bars is a small sample to pick from.

Copy the compiled Optimize Macd Settings Indicator file into your MQL4/Indicators folder, and the MT5 build into MQL5/Indicators, then restart the terminal and drag it onto a chart. The step-by-step guide with screenshots is at how to install MT4 and MT5 indicators.

FAQ

How does SweepWindow 600 pick the winning set?

The code builds each combination in the grid across those six hundred bars and scores it. Whichever scores highest becomes the set you see plotted, and everything afterwards uses that one choice.

Can the SweepWindow choice change mid-session?

Yes, and that is the main caution. The window rolls forward with new bars, so a different combination can win and the plotted line shifts, which a fixed-period MACD never does.

What does SignalMinExpand 0.00003 filter?

Crossings where the two lines barely separate. The floor takes a fraction of price rather than a fixed value, so it scales across symbols and removes the crossings that happen while both lines run together.

Does SweepStep 2 miss good combinations?

It can. Stepping by two halves the candidate count and therefore the calculation, at the cost of skipping every odd-numbered period. Setting it to one searches more thoroughly and runs noticeably slower.

Are results guaranteed?

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