Algorithmic trading — "algo trading" for short — means using pre-set rules or automated software to place trades on your behalf, instead of clicking buy or sell yourself every time. The logic can be as simple as "buy when price crosses this average" or as complex as a machine-learning model reacting to dozens of signals at once.
Why traders use it
- Speed. A bot can react to a price move in milliseconds — far faster than a human watching a chart.
- Consistency. An algorithm follows its rules exactly, every time, without hesitation or fatigue.
- No emotion. It won't panic-sell on a dip or chase a rally out of FOMO — it just does what it's told.
- Coverage. A bot can watch markets around the clock, across multiple instruments, without needing to sleep.
The trade-off: control
Handing trading decisions to software means you're trusting its logic completely. That's why the way you connect a bot to your account matters as much as the strategy itself — a well-designed setup lets automation run without ever exposing your login credentials, and keeps hard risk limits in place that the bot can't override.
Three common ways to automate
- Expert Advisors (EAs). Scripts built for platforms like MetaTrader 5 that run your strategy directly against your account.
- Signal-based automation. Tools like TradingView can fire an alert when your chart conditions are met, which then triggers a trade automatically.
- Custom API bots. For traders who write their own strategies, a scoped API key lets custom code place trades without ever touching your account password.
Getting started safely
If you're exploring automation for the first time, start small: test a strategy with tight risk limits before scaling up, and prefer setups where you can revoke access instantly if something goes wrong. Metafix's Algo Trading tools support all three approaches above, with broker-enforced limits you control from the app.
