Automated trading, forex robots and "AI trading" – what works and what to avoid

Automated trading means a computer program opens and closes trades based on rules. It is how most professional FX volume is traded. At retail level it ranges from genuinely useful tools to outright fraud.

#Legitimate forms

• Expert Advisors (EAs) on MetaTrader, written in MQL4/MQL5.
• cBots on cTrader, written in C#.
• Alerts and webhooks from TradingView that trigger orders.
• APIs from brokers such as Interactive Brokers and Saxo for traders who code in Python or other languages.

These are tools. They execute your rules with discipline and speed, but they do not create an edge that the rules do not have.

#Backtesting traps

• Overfitting: tweaking parameters until the past looks perfect. Test on data the strategy was not optimised on (out-of-sample) and walk-forward.
• Ignoring costs: spreads, commission, swaps and slippage can turn a profitable backtest into a loser, especially for short-term strategies.
• Unrealistic data: low-quality tick data or fixed spreads flatter scalping systems.
• Hidden risk: martingale, grid and "never close a loser" systems produce smooth equity curves until a single trend wipes the account out.

#VPS hosting

EAs running in your terminal stop when your computer sleeps. A virtual private server (VPS) near your broker's servers – often in London, Amsterdam or Frankfurt for European brokers – keeps them running with low latency. Some brokers provide a free VPS above a trading volume or balance. Check the provider's security and never store passwords in shared documents on it.

#"AI trading" apps and bots: the scam pattern

European regulators regularly warn about platforms promoted with fake celebrity endorsements and fake news articles claiming an "AI" or "quantum" trading system produces guaranteed returns. Typical signs:

• the "robot" is only available through a sign-up page that passes your details to call-centre "brokers";
• returns such as "€1,000 per day" are promised;
• the broker behind it is offshore or not named at all.

Real AI in trading is mostly used by institutions for research, execution and risk. There is no licensed product that guarantees profits. See clone firms and scams.

#Buying a robot

If you buy an EA, ask for a live, verified track record of at least a year, the maximum drawdown, the logic (trend-following, mean-reversion, grid…) and the risk per trade. Test it on a demo and then very small live size before trusting it.
