What you're being handed

The money is fake. All of it.

Every trade here is simulated. There is no live-trading mode, no button that turns one on, and no order-building code anywhere in the application — not disabled, absent. A test in the suite reads the exchange module and fails if anything resembling an order appears in it.

So nothing you do here can lose you money, and nothing here can make you any either. What it can do is tell you whether a strategy would have worked — honestly, which is rarer than it should be.

The numbers are deliberately unflattering

Fills are priced by walking the real order book rather than using the headline price, and real published taker fees are charged. That's why a brand-new position starts slightly negative: that's the fee, and it's real.

The app refuses far more trades than it takes, and records why. The refusals are the product. Most trading tools show you the wins.

There's a panel that computes what your track record would say if fees and slippage were ignored — the number most bots advertise — next to what actually happened. The gap between them is the point.

What we hold, and what we don't

Held: your email address, a hashed password, your simulated trades and settings, and — only if you switch it on — a two-factor secret.

Not held: exchange API keys, payment details, your real name, phone number or address. If you connect an exchange, the keys stay in your own browser and are forwarded per request. They are never written to the server's disk, and there's a test that connects with a marker string then reads every file on the server looking for it.

Connecting an exchange is entirely optional and read-only. The app cannot place an order with your key because it cannot place an order at all. Full detail on the privacy page.

Expect it to break, and expect resets

This is a beta run by one person. Things will be wrong. Some of them will be wrong in ways that look right, which is worse — if a number seems off, please say so rather than assuming it's you.

Paper accounts may be reset during the beta, and a reset clears your simulated positions and history. You'll be told before it happens where that's possible. Don't build anything you'd be sorry to lose.

The beta might end

It might end because the idea is disproved — which is a real possibility and the whole reason for running it. There is a measured threshold written down in advance: if cross-exchange gaps don't survive long enough to be tradeable, that feature stops.

If the site shuts down you'll get at least 30 days' notice by email, and an export of your own data before it goes. Your account and everything in it is deleted at that point rather than kept, quietly, forever.

Leaving is real

Delete your account from the account page at any time. It is a real deletion — the files are removed, not flagged as hidden. You don't have to email anyone or explain yourself.

What it will not do

The assistant answers two things: your own results, and how this app works. It won't tell you whether to buy something, or where a price is going.

That isn't squeamishness. A tool that executes what you configured is software; one that recommends specific trades starts to look like investment advice, which is a different regulator and a different business. The line is worth defending precisely because it's easy to cross by being helpful.

What would actually help

Use it like you mean it for a week, then tell me the moment you got confused or stopped believing a number. Not a feature list — the exact point where it lost you. That's worth more than anything else you could send.
