Fundamentals of MQL5

Learn how to construct a real custom indicator in MQL5, display two lines in a separate window, declare buffers, and implement candle-by-candle calculations using close prices and five-candle comparisons.

Explore using our second custom indicator in MQL5, test signals, copy code snippets, adjust conditions, and view the red line to verify buy and sell signals.

Create and manage virtual stop loss and take profit objects in MQL5, assigning names, setting prices, and handling buy and sell sides for automated exits.

Apply a time filter in MQL5 by declaring start and end times and using the time structure to compare current time against a trading window, with day-of-week constraints.

Learn how type casting in MQL5 handles converting numbers to strings and doubles to integers, and how explicit casts prevent data loss and compiler warnings.

Explore how to filter and identify news releases in MQL5 objects, testing object types, events, and descriptions to locate the next upcoming release.

Use the sleep function to time news checks in the news filter II, calculating minutes and seconds before the next release and converting to milliseconds.

Compute stop loss and take profit per trade by capping risk to a percentage of balance, and set the trade's volume accordingly using max lot, digits, and tick value.

Learn balance-based money management by calculating lot size from account balance and risk percent, using a check volume function and risk mode options like balance percent and auto lots.

Learn to implement partial close strategies in MQL5, closing portions of trades at target values while leaving remaining lots open, with practical coding steps.

Plot Fibonacci retracement in MQL5 by selecting the high and low from the last fifty candles and drawing the lines using code with corresponding time and price points.

Learn to create reusable buttons in mql5 using a function that defines name, position, size, color, and text, then display and delete them on a chart.
