🔒 US symbols live · more brokers next

Your rules. Your machine. Your keys.

Write what you want automated in plain English. TradeStudio turns it into an explicit, readable rule — then runs it locally against your own brokerage account. No servers holding your keys, no one trading on your behalf.

Runs on your PC, not our serversYour broker keys never leave your machineEvery rule is readable before it runs
Try it

Type a rule. Watch it compile and backtest.

One sentence in, a typed rule and ten years of daily bars out. No account, no email, nothing stored.

Where this is today

TradeStudio is live in Korea with three domestic brokers, and US symbols now run end to end — daily bars, per-market fees, backtest and arming — with your own API key pair from one supported US brokerage. What is not done is coverage: exactly one US brokerage is wired today, and Interactive Brokers, Schwab and Robinhood are not. Tell us which one you use and that is what gets built next.

How it works

Three steps, and you can read every one of them

1

Say it in plain English

“If it drops 3% from yesterday's close, buy $1,000 worth, take profit at 5%, stop at -5%.” That is the whole input.

2

Read the compiled rule

It becomes a typed rule — entry conditions, sizing, exits, risk limits — shown to you in full. If it does not match what you meant, it does not run.

3

Backtest, then arm it yourself

Nothing executes until you look at the backtest and explicitly arm the rule. Arming is your standing order, logged locally.

Why local

Most tools ask you to move your money. This one doesn't.

Cloud platforms need your keys on their servers, or need you to open an account with them. TradeStudio runs as a desktop app on your machine and talks to your existing broker directly. We never hold your credentials, your positions, or your orders.

  • No account transfer — keep the broker you already use
  • Credentials stored locally, encrypted, never transmitted
  • Works offline for everything except the one-time rule compile

One thing we do send

Turning your sentence into a rule happens once, on our server, using our language-model key — that is the only way to keep an API key out of a downloadable binary, where it could be extracted. So we do see the sentence you write. We never see your account, your keys, your positions, or your orders.

Questions

Which brokers are supported?
One US brokerage is wired today — you'll see it in the broker list below — plus three Korean brokers (KIS, Kiwoom, Toss). Interactive Brokers is next, which covers most markets outside the US. You link the brokerage account you already have — TradeStudio never opens or holds one.
Is this investment advice?
No. TradeStudio never proposes a symbol, a direction, or a strategy. It only structures what you already decided into an explicit rule. If you ask it what to buy, it refuses and asks you what you want automated instead.
Does a language model make trading decisions?
No. It is used once, at setup, to translate your sentence into a typed rule. While the rule runs there is no model in the loop at all — a deterministic engine reads the rule and nothing else.
What does it cost?
The Korean version is about USD 14 per month. US pricing is not set yet; waitlist members hear it first and are not charged during the beta.
Do I need to know how to code?
No. You write one sentence and read the rule it produces. There is no scripting language to learn.

Get told when your broker is supported

One US brokerage works today. Tell us which broker you actually use and the one rule you would automate first — that is what decides which broker gets wired next.

No spam. One email when your broker is supported.

TradeStudio is software. It is not an investment adviser, broker-dealer, or portfolio manager, and it does not recommend securities. You author every rule and you bear every outcome, including loss of principal.
