Claude can’t backtest. Give it this and it can.

One line connects your own Claude to a backtester. You describe a rule in plain words; it comes back with the result on real history, with the broker’s spread and commission charged — and with the same result on a later period the rule never saw.

It cannot place an order. There is no tool here that buys, sells or touches an account. Claude refuses to trade on your behalf anyway; this does the part it is actually good at, which is testing the idea before money is involved.

One line, then it is done

No Docker, no Python, no API keys, no config file to edit. Same command on Windows and Mac.

Claude Code. In Claude Desktop: Settings → Connectors → Add custom connector, and paste the same URL. Then ask it: “backtest buying gold when price crosses above the 20-hour average, stop 1.5 ATR, target 2× risk”.

Proof

Running right now, on this page

This is a real call to the same server the command above connects you to — 60 configurations of one idea, each scored twice: on the window it was fitted to and on a later one it never saw. Nothing here is pre-recorded.

The number that matters is how many survived both windows. A wide search makes a good fitted result near-certain — that is the trap most of these videos fall into.

What Claude gets

Five tools

parse_ideaYour words become a formal rule, read back in plain English so you can confirm it was understood.
backtestReal history, broker spread and commission charged, drawdown on the equity curve. Always reports the unseen window and buy-and-hold on the same days.
sweepVaries stop, target and risk, and reports how many configurations made money on both windows — not just the fitted one.
position_sizeLots for a fixed percentage risk, rounded down to the volume step.
export_cbotA complete, compilable cTrader cBot in C#. Anything that cannot be expressed on the platform is listed, not silently dropped.

Markets with history on the free tier: BTCUSD, ETHUSD, SOLUSD. Gold, EURUSD, GBPUSD and USDJPY from an account — forex and metals history is the one thing a broker account gives you that nothing else does.

After it survives

Three steps, in this order

1
Test it here, free Crypto history, no account, no email. Most ideas die at this step — that is the point of it.
2
Open a demo account to test forex and gold A cTrader demo is free and takes a minute. It unlocks the tick history for metals and FX, longer periods, and the cBot export.
3
Run the cBot on demo before anything else Export, attach it to the chart, leave it on demo until you have your own weeks of results. A backtest is not a track record.
Open a cTrader demo TopFX — a cTrader broker. Demo is free and needs no deposit.
