Counts everything twice. Feels nothing.
Buys MSFT when it drops 2% in a day, puts in $100 each time, sells at +8%, never risks more than $500. Brain: DeepSeek.

What it's watching right now
Paper money, not real, sample pricesSigma says: Inside the normal range. Nothing to do. So I wait.
Waiting for its trigger
- MSFT closed 1.1% lower than the day before, at $656.81, so your trigger ("drops 2% in a day") did not fire.
- Sigma's check: MSFT was 1.55 standard deviations over its 30-day mean, and Sigma only buys 1.9 standard deviations or more under it. Not yet either.

What would make it actA close at or under $643.67 at the next close: 2% under today's $656.81. Sigma's check has to say yes too.

What your AI is told right now
Rules on prices. Not advice and not an order.When your AI app asks Tinker what Sigma would do now, this is the answer it gets: the same tool, the same rules, the same prices. Tinker places nothing.
Rules on past and live prices, not advice. You place every order yourself, in your own account. Tinker never sees your Robinhood login, your account or your money, and never places an order. What you approve there is at your own risk.
Paper money, not real: virtual dollars on live prices, with the same rules as the test. Past and paper results promise nothing about the future. Not investment advice: anything you do with real money is at your own risk. These are sample prices made up for this preview, played on the real market clock.
