Sign in

QuantCrystal uses email sign-in links instead of passwords. There is nothing to choose, forget, reuse, or leak — and your inbox was already the recovery factor for any password we could have asked you for.

There is no password. We email you a link and clicking it signs you in — if you have no account yet, this creates one. Signing in also subscribes you to QuantCrystal updates — occasional product email, never sold or shared. Every message carries a one-click unsubscribe, and you can turn it off any time from your profile.

Paper trading only. No real money, no brokerage credentials, no card.

What you get with an account

  • Unlimited paper trading accounts, with per-account fees and slippage.
  • Equities and crypto, long and short — including crypto shorts, which most paper venues do not offer.
  • An append-only fills journal that records the mark, the slippage and the fee behind every fill.
  • An Alpaca-compatible API, so an existing bot moves over by swapping its base URL.
  • Your record stays private unless you choose to publish it. What publishing exposes is listed on the home page, in full, before you decide.
