Fees

Spreadr charges a 0.5 bp (0.005%) builder fee on each fill it executes for you. That's the whole fee model — no subscription, no deposit, no custody, no charge for trades that don't fill.

The fee is collected through each venue's builder/referral mechanism, so it appears on the exchange's side (deducted from your fill), not as a separate Spreadr invoice. Orderly legs are currently exempt — no builder fee is charged there today. Each venue's page in Exchanges notes how the fee shows up.

Exchange fees

On top of the builder fee, you pay each venue's own trading fees at your account's fee tier — typically a small maker rebate or fee on the resting leg and a taker fee on the hedge leg. These are set by the exchanges, not Spreadr; check each venue's fee schedule for current rates.

What this means for your spread math

Your entry threshold needs to clear round-trip costs: venue fees on both legs (entry and exit) plus 0.5 bp per fill to Spreadr. The terminal's spread chart shows the gross spread — make sure your target leaves room after fees.
