Algo trading via EAs in MetaTrader 4 is perhaps the most popular way to automate trading in forex and CFD markets<\/a>. That makes sense because MT4 is one of the more prominent platforms and because it has a massive base of community-made EAs on top of an already solid pre-made set.<\/p>\n\n\n\n

However, getting into automated trading can be scary. It seems overly technical at first, and many traders are afraid of their algorithm losing control and somehow spending all their money. Sure, that kind of thing can happen if you dive into algo trading recklessly. But if you do it right, it\u2019s almost impossible.<\/p>\n\n\n\n

This article will cover the basics of what algo trading is, how traders normally use it, and how they can start doing so in MetaTrader 4<\/a>.<\/p>\n\n\n\n

What is algo trading?<\/strong><\/h2>\n\n\n\n

Algo, in this case, is short for algorithm or algorithmic. In other words, algo trading is an \u0627\u0644\u062a\u062f\u0627\u0648\u0644 \u0627\u0644\u0622\u0644\u064a<\/a> routine that follows pre-programmed rules. Different platforms use different names for these algorithms. In \u0645\u0646\u0635\u0629 MT4<\/strong> and MT5, for that matter, they go by ‘Expert Advisors’ or EAs.<\/p>\n\n\n\n

The rules are different, and they depend on the exact tool the trader is using. Sometimes EAs will react to price action, other times they’ll rely on specific points on technical indicators. <\/p>\n\n\n\n

However, they monitor the markets constantly and make decisions based on predetermined factors. This constant monitoring allows traders to easily let their systems run on multiple markets without the need to intensively multitask.<\/p>\n\n\n\n

In other words, this means that EAs take any sort of emotion out of the equation. They simply follow their routine, and their success depends on how well the algorithm fits market circumstances.<\/p>\n\n\n\n

The three types of expert advisors (EAs)<\/strong><\/h2>\n\n\n\n

Traders mostly use Expert Advisors<\/a> to fully automate their strategies but that\u2019s not all they\u2019re capable of. In fact, they can also be a useful tool for traders who simply want to supplement their trading routine with some raw machine logic. There are three types of EAs in general:<\/p>\n\n\n\n

Signal-based EAs<\/strong>: <\/h3>\n\n\n\n

These don’t do any actual trading on behalf of the trader. Instead, they use \u0627\u0644\u0645\u0624\u0634\u0631\u0627\u062a \u0627\u0644\u0641\u0646\u064a\u0629<\/a> and price action patterns to generate trading signals. This may alert traders to opportunities they’d otherwise miss, but allows them to maintain full control of their trading routine.<\/p>\n\n\n\n

Semi-automated EAs<\/strong>: <\/h3>\n\n\n\n

As their name implies, these EAs have some degree of automation but don’t go through the entire trading process. For instance, they may open trades but not close them or allow the trader to set their own TP\/SL levels. This allows the trader to intervene and keep a large degree of control while taking some pressure off their trading.<\/p>\n\n\n\n

Fully-automated expert advisors (EAs)<\/strong>: <\/h3>\n\n\n\n

The most common type and the one most traders consider the default. They fully automate trading<\/a> and do so without any need for human intervention. However, they won’t simply eat away at trader funds if they go haywire. They can be shut down at any time, giving the trader full control back.<\/p>\n\n\n\n

What do expert advisors (EAs)<\/strong> do?<\/strong><\/h2>\n\n\n\n

Some traders are still wary of letting a program run their trading because they think EAs only open and close trades. However, that’s not true; they have many other functions such as:<\/p>\n\n\n\n
