Les meilleurs codes sources MQL4 et MQL5 selon les notes des utilisateurs

Forget about BMP files like a bad dream. Thanks to this library, you can now use the PNG format, which has a number of advantages, such as being more compact without losing image quality and maintaining transparency.

Dans la quatrième partie du livre, nous nous concentrerons sur la maîtrise des fonctions intégrées (API MQL5) et nous nous pencherons progressivement sur les sous-systèmes spécialisés. Tout programme MQL5 peut utiliser de nombreuses technologies et fonctionnalités. Il est donc logique de commencer par les fonctions les plus simples et les plus utiles qui peuvent être utilisées dans la plupart des programmes.

Time-related functions for empirical detection of server time zone and daylight savings mode (DST) from history of quotes

This script saves a predefined set of economic events from the MetaTrader's built-in economic calendar into CSV file.

Marking the extreme highs and lows (OHLC) together with the extreme bid and ask prices

This indicator displays current events on the chart and allows you to export the calendar to archives for backtesting, automatically fixing time discrepancies between the history of bars and the history of events. This is an improved version of CalendarMonitorCached indicator from the algotrading book.

BollingerBandsEA trades according to Bollinger Bands.

Unfortunately, I discovered that some brokers are a bit sloppy with the server time change due to the daylight saving time (DST), which I did not expect and which surprised me a lot. Here is a script with which anyone can check their broker.

BMA MetaTrader indicator or Band Moving Average — was created by using the original moving average indicator and the idea from one of the site's visitors. The indicator displays itself in the form of three lines: the central one is the standard MT4/MT5 moving average (which can be simple, exponential or weighted), the upper line is the same as the central one but lifted up by 2% (by default), the lower line is the same as the central one but pushed down by 2%. Those two additional lines serve as the support and resistance levels. The indicator is available for both MT4 and MT5.

Bollinger Squeeze Advanced MetaTrader indicator — is a complex indicator consisting of two components: A measure of trendedness based on the Bollinger bands and Keltner channel "squeeze". A trend direction and strength histogram based on one of the following eight oscillators: Stochastic, CCI, RSI, MACD, Momentum, Williams % Range, ADX, DeMarker.

Coppock MetaTrader indicator — is an implementation of the famous Coppock curve indicator first created by Edward Coppock in 1962. The indicator shows long-term buy and sell opportunities (classically, it is used for only buying) by measuring the weighted moving average (with a period of 10) of the sum of two rates of change (with a period of 14 and 11). It is the classical version. In this MetaTrader version, you can modify the parameters of the basic indicators. You can use this Coppock indicator in MT4 and MT5.

Laguerre MetaTrader indicator — a completely custom indicator that doesn't rely on the standard MT4/MT5 indicators. It shows the weighted trendline in the separate window of the chart. It can be used for simple entry and exit signals. The indicator is available for both MT4 and MT5.

TD Sequential Ultimate MetaTrader indicator shows all parts of the TD Sequential method developed by the legendary technical analyst, Tom DeMark. TD Sequential Ultimate displays Buy and Sell Setups, including the Setup Perfection arrows, Buy and Sell Countdowns, including the failed count 13 attempts, and TDST Support and Resistance levels. Unlike many other implementations of the TD Sequential method, this indicator offers multiple improvements:

An indicator which visualizes how volume changes over time within each bar. It shows tick volume in a rolling histogram format.

This is a simple indicator to display histogram of custom bars' durations in minutes. Applicable for renko boxes, PnF, equivolume bars, etc.

A SuperTrend indicator that plots trend direction using ATR volatility to create dynamic support/resistance levels for MetaTrader 5.

This Bot detects the open of a new candle on any set timeframe, thereby making it easier to run a one-time code, place trades and call other functions. The code is written in the OnTick() function.

This indicator will shows the time remaining until the end of the candle. You can choose colour and the font size.

Calculate DST for USA, EUR, AUD and RUB and the offset time of the broker automatically from the 70's until 2030 - even in the Strategy Tester of MQ.

La septième et dernière partie du livre traite des capacités avancées de l'API MQL5, qui seront utiles lors du développement de programmes pour MetaTrader 5. Il s'agit notamment des symboles financiers personnalisés, des évènements du calendrier économique intégré et de technologies générales telles que les réseaux, les bases de données et la cryptographie.

Dans la cinquième partie du livre, nous approfondirons les API associées au trading algorithmique, notamment l'analyse et le traitement des données financières, la visualisation des graphiques, l'automatisation et les interactions avec les utilisateurs.
