Institutional crypto ATS	0.02-0.10%	0.05-0.15%

Fees are set per-market via the Market struct at registration:

{
  "symbol": "BTC-USD",
  "maker_fee": "0.001",
  "taker_fee": "0.002"
}

Compliance Costs

ATS registration, compliance infrastructure, and regulatory reporting are included in all institutional tiers. There are no separate compliance surcharges.
