What is a forex trading system?
A forex trading system is essentially a set of rules used to execute trades on one or more currency pairs. While these systems can be implemented manually, many traders use automated systems – based on computer code – to take emotion out of the equation and execute trades more efficiently. These automated systems are effectively ‘trading robots’ that can monitor the markets at any time of day, looking for opportunities and executing trades according to a set script.
Creating vs buying an automated forex trading system
You can create an automated forex trading system for many of the platforms that IG offers, including MetaTrader 4 (MT4), ProRealTime, and our regular online trading platform via an API. With MT4 and ProRealTime, it’s also possible to buy and install pre-built systems made by a third party.
Building a custom system
The main benefit of building a custom system is that the options are practically limitless – the only constraints being your imagination and what can be coded. However, building a bespoke system will require an in-depth understanding of financial markets, trading and technical analysis . You’ll also need to convert your system into code, though it is possible to hire a developer once you have designed the system on paper.
Buying an off-the-shelf solution
If you use MT4 or ProRealTime, you also have the option of buying an off-the-shelf solution, known as an ‘Expert Advisor’ (EA) on MT4 and an ‘automated trading strategy ’ on ProRealTime. While using one of these systems is much easier than coding a strategy from scratch, it’s important to research and test any third-party solution thoroughly to make sure it fits in with your trading goals and actually does what it says. This is because many third-party solutions make bold claims – like being the ‘best forex trading system ’ – but fail to live up to the hype.
