MQL4 In Depth

Build a MQL4 expert advisor that uses modulus a random number to detect odd or even, open buys or sells when trades are closed, with stop loss and take profit.

Learn to organize MQL4 code by turning trade commands into a reusable trade engine function, handling return types and inputs like volume, and calling it from on tick.

Learn to add a moving average filter to an expert, using an exponential moving average on close price to trigger buys above and sells below the moving average.

Add a parabolic SAR filter to the MQL4 expert with step 0.02 and max 0.2, using iSAR values to drive buys and sells and enforce one trade per candle.

Add a MACD filter to a MQL4 expert by configuring MACD inputs, reading main and signal lines, and buying when the main line exceeds the signal line and price confirms.

This lecture demonstrates implementing a trailing stop in a MQL4 expert advisor to maximize profits by moving the stop loss behind each profitable trade as prices move.

Create a basic custom indicator in MQL4, learn how indicators differ from expert advisors, and plot signal arrows when moving averages cross, using buffers, colors, and a candle-by-candle loop.

Add a moving average filter to a custom indicator and detect crossovers by comparing two moving averages over two candles, plotting buy and sell arrows when the cross occurs.

learn to copy and adapt existing signal conditions into an MQL4 indicator, using moving averages to generate buy and sell signals and validate entries across candles.

Learn how to use iCustom in MQL4 to call a custom indicator, retrieve its parameters and buffers, and generate buy and sell signals for a hedge ea with trailing stop.

Learn to automate a hedge in MQL4 by tracking the last trade's price, volume, and type, computing distance to entry, and closing open trades with a magic number.

Explore how hedge II implements a hedging strategy in MQL4, using hedge distance, stop loss, take profit, and a volume sequence that scales trades.

Learn how to use take profit and stop loss logic to close trades by identifying the youngest and oldest open trades and syncing with the last closed trade in history.

Consolidate the hedge logic by updating last price, last lots, and last trade from a single void function that does not return a value on every tick.

Hedge V session demonstrates fixing an error in the MQL4 code by validating the last close trade and first open trade in history; the instructor reviews and updates.

Create interactive buttons on charts using MQL4's object create for buttons, set colors, size, position, and text, then assign actions to execute buy or sell commands via an expert advisor.

Create a reusable button function to replace duplicated code. The function accepts name, color, width, height, position, and text to produce buy and sell buttons.

Learn to use the on chat event function in MQL4 to detect chart object clicks and trigger actions, such as tweet entry for buy or sell trades.

Learn how to create and position text labels on MQL4 charts, set fonts and colors, and build a reusable create_text function to display volume, stop loss, and take profit labels.

Learn to create input boxes and configure their attributes in MQL4, including chart id, name, type, position, size, width, height, font, and color, to build an interactive trading dashboard.

Create a green rectangle behind dashboard elements on the chart, set attributes and layering with the init function, and delete all objects during expert refresh to keep elements visible.

Read volume, stop loss, and take profit values from a display object via object get, converting strings to doubles on every tick.
