What automation means
Automated trading uses code to place or manage orders. On MetaTrader this is an expert advisor (EA); on other platforms it may be a bot or a direct API connection.
Automation can remove emotion and run around the clock, but it also executes exactly as programmed, bugs included.
Common approaches
EAs run inside the platform; API trading connects your own code to the broker's systems; copy trading follows another trader. Each has different setup and risk.
MetaTrader uses MQL, cTrader uses C#, and many brokers expose REST or FIX APIs for custom systems.
- Expert advisors (in-platform)
- Broker APIs (custom code)
- Copy trading (follow others)
Risks to manage
Test thoroughly on a demo, monitor live runs, and understand that past performance does not predict future results. Connectivity failures can stop automation unexpectedly.
Treat any 'profitable bot' claim with skepticism; verify independently.
