MQL5 Basics: Guide to creating MT5 Indicators

Learn to create a simple moving average indicator in mql5, set up initialization and series with one input period (14), and prepare for compilation to mt5.

Learn to build a simple moving average indicator in mql5, preparing data series, handling time and price fields, computing a summation over the input period, and producing the sma value.

Discover how to extend a simple indicator by implementing a price function that selects open, high, low, close or derived prices (median, typical, weighted) for a simple moving average.

Create a new MT5 indicator that calls a default indicator, set up the handle, configure inputs (period, method, apply price), and compile for live charts.

Refresh a virtual indicator by enabling the series, recalculating values with a limit using input period, and copying results to plotting buffers for a moving average indicator; ensure error-free compilation.

Learn to build a simple MQL5 indicator using a dedicated handling class, following a template and inputs for fast EMA, slow EMA, and applied price.

Learn to implement a Monk D indicator in MQL5, refresh the indicator, manage arrays and controls, assign values to main and signal buffers, and validate inputs for MT5 indicators.

Create the initialization function for a colored indicator using a moving average. Configure three colors red, white, and yellow, and manage two buffers, one plot.

Learn how to color a multi-colored MT5 indicator using a moving average, including color logic for above, below, or within price, and how to assign buffer values.

Explore how to create and manage chart objects—arrows, lines, rectangles—and integrate them with indicators like moving averages in mt5, including moving trend lines and self-deleting scripts.

Learn to create, draw, modify, and delete rectangle objects in MQL5, using time and price parameters, color changes, and object properties to build and manage indicators.

Initialize a bufferless MQL5 indicator by creating a single virtual buffer and copying input parameters from simple indicators. Use onInit to set up and reuse the calculation logic for drawing.

Create and initialize a bufferless MT5 indicator by building a chart handle, testing initialization, and refreshing to ensure bars calculated meet the input period.

Implement a bufferless MT5 indicator by calculating price data, managing objects, and drawing colored lines based on price relative to high and low, with time-stamped plots.

Learn to finalize a bufferless mt5 indicator by implementing move line and create line functions, using imported trend line utilities, object management, and a robust delete workflow.

Learn to create an MQL5 arrow template indicator with up and down arrows, colors, and plot indices using uncalculated buffers.

Continuing the simple arrow indicator template, this lecture sets arrays, copies control values, and builds the main loop with buy and sell conditions and buffer updates.

Create a two moving average cross indicator in MT5 using buffers to plot up and down arrows when the fast MA crosses the slow MA, with adjustable periods.

Develop a moving average cross custom indicator using fast and slow arrays, initialize and refresh buffers, and display arrow signals when the fast crosses above or below the slow.

Build a bufferless MT5 arrow indicator by creating a reusable template, initializing buffers, and implementing a buy/sell logic that plots arrows on the closed candle with a draw arrow function.

Learn to build a bufferless arrow indicator in MQL5 by creating, moving, and deleting arrow objects, using the MQL5 reference and on_start setup.
