Adding Sound, Email, and Push Alerts to a Color-Coded Indicator
Summary
The document explains how to add notifications to a color-coded MetaTrader indicator. It introduces inputs for selecting the signal bar, enabling sound, limiting alert counts, and turning email or mobile push messages on or off. Separate buy and sell routines detect a transition into a chosen color index, then assemble a message with the symbol, chart timeframe, timestamp, and prices derived from the close and spread.
The routines are called after the indicator’s calculation cycle, using the color buffer and price arrays. A helper converts the chart timeframe enum into text. The document assumes each alert routine is called only once from the calculation block and depends on an external smoothing library for the underlying indicator. It provides implementation details, but no performance evidence or discussion of signal validity; alerts report indicator state and do not establish that a trade is profitable.
Key ideas
- A color-buffer transition can be used to detect buy and sell signals.
- Separate inputs let users control sound, email, push notifications, signal-bar selection, and alert counts.
- Alert messages can include the symbol, timeframe, timestamp, and prices computed from close and spread data.
- The example assumes each signal routine is called once after the indicator calculation cycle.
