Flow Traders — institutional liquidity provider

Flow Traders Ltd operates as a multi-asset liquidity provider. It holds tier 1 licenses from the FCA and SEC/FINRA. The firm claims to serve over 2,000 institutional counterparties, but self-measured figures require independent verification.

Regulator	Licence number	Jurisdiction	Tier	Source
FCA	960434	UK	tier-1	open source ↗

Tier classification follows the same scale as the retail register: tier-1 = FCA/ASIC/CFTC-class supervision, tier-2 = CySEC/FSC-Mauritius/MFSA-class, tier-3 = offshore registration. A tier-2 licence is genuine supervision without an investor compensation scheme — never misread it as tier-1 protection.

What the firm commits to

Claims specific enough to be falsified — and the ones that remain the venue's own measurement.
