Practice trading.
Find out what it really costs.
Live market prices, simulated money, and results that include the fees and slippage most practice tools quietly leave out. Koineti shows you the trades it refused, too — because that's where the truth usually is.
A flattering simulator is worse than none at all.
Leave out the costs and any strategy looks like a winner — right up until it's your money.
Real prices, fake money
Live exchange data and order books. You practise against the market that exists right now, with a balance that costs nothing to lose.
Costs are charged
Every simulated fill walks the real order book and carries the venue's actual fee. The number you see is the number you'd have got.
It can't trade for real
Not a setting that's switched off — the capability isn't in the product. No API keys are requested, so nothing here can reach your funds.
Refusals are shown
Books too thin, gaps eaten by slippage, spreads that mean two coins share a ticker. Every refusal is logged with its reason.
What "beta" actually means here.
Most products say beta and leave you to work out the consequences. Here they are.
Your data may be reset
Accounts and paper-trading history can be wiped when the storage format changes. Don't build a record here you'd be upset to lose.
Recovery depends on email
Password reset works only if this server has email configured. Check here — if it says unavailable, a forgotten password can't be recovered by anyone, so pick one you'll remember.
Features are still landing
Parts of the desk are half-built and things will move between visits. If something looks broken, it might genuinely be broken.
What isn't going to change
It stays paper-only. No live trading, no exchange keys, no route to your funds — that's structural, not a beta limit we'll lift later.
Find out what your strategy actually does.
Two minutes to set up. Fake money, real costs, and no way to lose anything but an assumption.
