MQL5 Developer Brief — MACD 3-Timeframe Continuation Alert

I need a simple MT5 custom alert indicator/scanner.

It must scan a list of FX pairs and alert me when my MACD continuation setup appears.

Symbols

The tool must allow me to enter a custom list of symbols, for example:

EURUSD, GBPUSD, USDJPY, USDCHF, AUDUSD, USDCAD, NZDUSD, EURJPY, GBPJPY, AUDJPY, CADJPY, CHFJPY, NZDJPY, EURGBP, EURAUD, EURNZD, EURCAD, EURCHF, GBPAUD, GBPNZD, GBPCAD, GBPCHF, AUDNZD, AUDCAD, AUDCHF, NZDCAD, NZDCHF, CADCHF

It must handle broker suffixes/prefixes if needed.

MACD settings

Default MACD settings:

12, 26, 9

These must be adjustable.

Timeframes

Use:

D1 = bias
H4 = confirmation
H1 = early entry trigger

These timeframes should preferably be adjustable.

Buy alert rules

Send a BUY alert when all conditions are true:

1. D1 bullish bias
   MACD main line is above zero.
2. H4 bullish confirmation
   MACD main line has crossed above the signal line, or is already above the signal line.
3. H1 early bullish trigger
   Histogram turns positive / green.
   The MACD line does not need to be above zero.

Alert message example:

BUY continuation setup: EURUSD — D1 bullish, H4 bullish, H1 early trigger

Sell alert rules

Send a SELL alert when all conditions are true:

1. D1 bearish bias
   MACD main line is below zero.
2. H4 bearish confirmation
   MACD main line has crossed below the signal line, or is already below the signal line.
3. H1 early bearish trigger
   Histogram turns negative / red.
   The MACD line does not need to be below zero.

Alert message example:

SELL continuation setup: GBPJPY — D1 bearish, H4 bearish, H1 early trigger

Alerts

The tool must support:

• MT5 pop-up alert
• Push notification to mobile
• Email alert if possible

Very important:

Only one alert per setup.
Do not repeat the same alert every tick or every candle.

A new alert should only be allowed after the setup has reset and appears again.

Other requirements

• No automatic trading.
• No opening or closing trades.
• Alert/scanner only.
• It can be attached to one chart and scan all listed symbols.
• It should show a very simple table if possible: symbol, D1 status, H4 status, H1 status, final alert status.
• Keep the design simple and reliable.
