Forex and Gold Trading Bot With Claude: The MT5 Route

1Why MT5 Is the Usual Home for Forex Bots

MetaTrader 5 is free, most forex brokers offer it, and it runs bots called Expert Advisors written in MQL5, a language Claude can write.

MT5 also has a Strategy Tester for backtests and a demo account option at almost every broker. That means you can build, test and watch a bot without spending money. Forex trades 24 hours a day, five days a week, so a bot on a VPS can follow your rules while you sleep.

2How to Build a Forex Trading Bot Using Claude

Write your rules, ask Claude for an MQL5 Expert Advisor, compile it in MetaEditor and test it on demo.

A starter prompt: Write an MQL5 Expert Advisor for MT5 that trades GBPUSD on the 15 minute chart. Enter on a breakout of the London session high or low, stop loss at the other side of the range, take profit at 2 times the stop, risk 1% of the balance per trade, no trades on Friday after 18:00 server time, and add comments. Then paste it into MetaEditor, compile, fix any errors with Claude, and run it in the Strategy Tester.

1. Write entry, exit and risk rules in plain English
2. Ask Claude for an MQL5 Expert Advisor with inputs and comments
3. Compile in MetaEditor and paste any errors back to Claude
4. Backtest, then run on a demo account for a few weeks

3How to Make a Gold Trading Bot With Claude

Gold works the same way, but tell Claude the exact symbol name and contract size your broker uses.

Brokers name gold differently, such as XAUUSD, GOLD or XAUUSD.m, so check your Market Watch list and give Claude the exact name. On many brokers one standard lot of gold is 100 ounces, so a 10 dollar move can mean a 1,000 dollar swing on one lot. Ask Claude to size each trade from your risk percent and stop loss, not from a fixed lot. Gold spreads also widen around big news like US jobs data, so many people add a rule to pause trading around those times.

4Prop Firm Rules to Check First

If you plan to run a bot on a prop firm challenge, read the firm's rules before you start. Breaking one can end the account.

Many prop firms limit or ban certain Expert Advisors, copy trading, trading during big news, very short holding times or using the same bot as thousands of other traders. Almost all have a daily loss limit and a total loss limit. Ask Claude to build those limits into the bot so it stops trading before it breaks a rule. When unsure, email the firm and ask in writing.

5Building It Yourself or Letting AI Trade for You

Building is a great way to learn, but it comes with testing, hosting and fixing. A ready made AI bot skips that part.

If you enjoy the process, keep improving your EA one change at a time and track every result. If you want the benefit without the upkeep, you can let AI trade for you with a ready made bot and spend about 5 minutes a day checking in. Both carry risk, so start small.
