Let AI trade. On your terms.
reTrade sits between the AIs that trade for you and your broker. Every order they send through it is checked against your rules, and every decision is signed into a record you own.
Pre-release
Every order stops here first.
Most go straight through; some are cut down, held for you, or stopped.
- Buy 10 AAPL: go ahead.
- Buy 204 NVDA: cut down to 6.
- Buy $12,000 VTI: waits for you, then goes ahead when you say yes.
- Buy 500 ZOOM: stop, no exact match for the stock.
- Buy 90 TSLA: stop, the price is 41 seconds old.
Example on a simulated account. Nothing was traded.
Write one rule. Watch it hold.
Your rule
Only you can change this rule. A tighter limit applies at once; a looser one waits 24 hours.

Investors
An AI can move your money at 3 a.m. The risk is yours.
Rules you sign once, checked on every order. Big orders wait for you. One button stops everything.
AI trading apps
One bad night for your agent becomes your headline, and your own logs can’t prove what happened.
Put reTrade in front of your trading connection: four answers and a receipt your users own.
Brokers
Outside AI agents send orders into your customers’ accounts, and some brokers’ terms leave the risk with the customer.510
One check across every AI a customer connects, and a record of why each order went through.
Insurers
AI trading is hard to cover when the only evidence is the company’s own logs.
A hard cap on what any AI can do, and signed, chained records you could check yourself.
The engine is built. Then we tried to break it.
0.2 msto check every rule on an order
- 1.5 msfor the whole signed decision
- 20,000random orders, all agreeing with an independent re-check
- 400orders from four AIs racing for one stock. The limit held.
Our own test run, 19 Oct 2026, simulated orders, one machine.
The engine isn’t available to the public yet; its orders go only to a simulated broker.
No record, no coverage.
Insurers pay for what they can check. Capped AIs and signed records could make AI trading insurable; we haven’t found anyone insuring it today. Planned. Plans depend on legal review and broker approvals.
How insurance would workLet AI trade. Keep the rules. Keep the receipts.
Join the waitlist for early access. The reTrade app, for everyday investors, will be the first place it runs.
