<\/figure>\n\n\n\n When you can create an automated trading tool, you can create an automated profitable tool.
But that makes it more difficult to create, and we will explain why.
<\/p>\n\n\n\n
What is MT5?<\/h2>\n\n\n\n
MT5, officially named MetaTrader 5, is a trading tool developed by MetaQuotes.<\/p>\n\n\n\n
This trading tool allows you to<\/p>\n\n\n\n
- Trading Forex and other currencies (manually)<\/li>
- Automatic trading<\/strong> using EAs<\/strong><\/li>
- Back testing of created EAs<\/li>
- Display charts<\/li><\/ul>\n\n\n\n
You can do these things. However<\/p>\n\n\n\n
The main function is automatic trading<\/strong>.<\/p>\n\n\n\n
By using this automatic trading function, MT5 will automatically buy and sell as long as the PC is turned on and MT5 is running.<\/p>\n\n\n\n
What is EA?<\/h2>\n\n\n\n
What is needed to perform this automatic trading is a program called an EA<\/strong>.<\/p>\n\n\n\n
EA stands for Expert Advisor. The literal translation is “professional advisor,” but the name seems to reflect the nuance of an expert robot that performs trading.<\/p>\n\n\n\n
EA = Automatic trading tool<\/p>\n\n\n\n
When you see the word EA, you can think of it as a program that performs automated trading<\/strong>.<\/p>\n\n\n\n

<\/figure>\n\n\n\nWhat is MQL5?<\/h2>\n\n\n\n
So how is this EA made?<\/p>\n\n\n\n
This is where the word MQL5 comes in.<\/p>\n\n\n\n
MQL5 is a programming language for creating EAs<\/strong>.<\/p>\n\n\n\n
In other words, you create an EA on MT5 by programming in the MQL5 language.<\/p>\n\n\n\n
You can create an EA by coding in MQL5 and compiling it.<\/p>\n\n\n\n

<\/figure>\n\n\n\nTherefore, to run an EA, you need to know<\/p>\n\n\n\n
- How to use the MT5 software<\/li>
- Understanding and coding in the MQL5 programming language<\/li>
- How to run EAs<\/li><\/ul>\n\n\n\n
You need to understand the following three things.<\/p>\n\n\n\n
How to start automated trading<\/h2>\n\n\n\n
The above information is summarized in the diagram below.<\/p>\n\n\n\n
<\/figure>\n\n\n\nProgramming on MT5 using the language MQL5 \u2192 Create EA \u2192 Execute the created EA on MT5.<\/p>\n\n\n\n
Only then can you start automated trading<\/strong>.<\/p>\n\n\n\n
In other words, you need to have
knowledge of finance as well as programming knowledge, and you also need to understand how to use tools such as MT5 and EAs.
This is why it is difficult for many people to start automated trading.
<\/p>\n\n\n\nThere is a way to purchase EAs from an external vendor without programming, but
since you are trading with strategies created by others, you often cannot modify them or make the trades you want to
make.<\/p>\n\n\n\nEA Conversion Service at Contra<\/h2>\n\n\n\n
Contra is a service that converts strategies created on the app into EAs.<\/p>\n\n\n\n
You can back-test on the app and find a good strategy by yourself.<\/p>\n\n\n\n
