What is it?

An Expert Advisor (EA) is a program that trades automatically in MetaTrader 4 or MetaTrader 5. It is written in MQL4 or MQL5 and follows fixed rules for entries, exits and risk.

Why use it?

An EA follows your rules on every tick, without hesitation or fatigue, and it can be tested on historical data before it risks real money.

How I build it

  • Write the strategy down as exact rules.
  • Code it in MQL4 or MQL5 as an Expert Advisor or indicator.
  • Build in position sizing and risk rules.
  • Backtest in the MetaTrader Strategy Tester before anything goes live.

Why hire me?

My own EA, Sigma7 Gold Swing, is published on the MQL5 Market.

FAQ

Questions about MT4 / MT5 Expert Advisors

Can you turn my trading strategy into an MT5 EA?

Yes. We write your strategy down as exact rules for entries, exits and risk, and I code it in MQL5 as an Expert Advisor for MetaTrader 5 (or MQL4 for MetaTrader 4).

Do you build risk-based position sizing?

Yes. Position sizing and risk rules are built into every EA. My guide “Risk-based position sizing in MQL5 (with code)” shows how lot size is worked out from the risk per trade and the stop loss.

How do you test an EA before it trades real money?

I backtest it in the MetaTrader Strategy Tester before anything goes live. My guide “How to backtest an Expert Advisor in the MT5 Strategy Tester without fooling yourself” explains the method.

Do you also write MQL5 indicators?

Yes. I write indicators as well as Expert Advisors, in MQL4 or MQL5.

Have a bot, a backend or a strategy in mind?
