Liquid Mercury vs Talos: Institutional Trading Platforms Compared

Summary

• Talos describes itself as a provider of software-as-a-service products for institutional customers. Its site lists a trading platform, white label, RFQ platform, portfolio construction, portfolio and risk management, treasury and settlement, and analytics. [T1]
• Liquid Mercury offers Mercury Pro (an execution and order management system with algos, risk controls and APIs), Mercury OTC (an electronic, white-labeled OTC platform) and Mercury RWA (tokenized assets). This page compares the first two with Talos.
• Fit. A team that wants one vendor for execution plus portfolio construction and analytics should look closely at Talos's module list [T1]. A team that wants a white-labeled electronic OTC desk, a specified algo suite, or the Risk Engine, kill switch and auto-liquidation controls should look closely at Liquid Mercury. Most buyers will want to see both.

Execution and algorithms

Talos's FAQ lists TWAP, Percent of Volume, Pegged, Steady Paced, Time Sliced, Multileg and others [T8]. Its trading page describes an algorithm suite that can target exchange and OTC liquidity at once and can be tuned or calibrated, a fee-aware smart order router, and liquidity aggregation [T2]. For prediction markets it names Iceberg, Pegged, Sniper and TWAP [T2].

Liquid Mercury's Algo Suite has seven algos: Sweep, Spreader, Market Making, TWAP, OTC Posting, Volatility and Chase. The Sweep algo aggregates books and routes to several venues, and underlies several others. The Volatility algo trades options on a trader-defined implied volatility with an optional delta hedge. Market Making quotes on one exchange against another and hedges fills. See the full specification in the Algo Suite.

The two lists name different algos, and the Talos FAQ list ends with "and others" [T8], so it may not be exhaustive. Check whether the algo your desk needs exists, and how it is configured, in a demo.

OTC and RFQ

Talos's RFQ Platform page describes centralized, standardized RFQ workflows with spread-to-fix quoting, a liquidity provider network, and integration with OMS, PMS, custodians and fund administrators [T3]. Its trading page also describes multi-dealer prices over RFQ, RFS and ESP [T2].

Mercury OTC replaces voice and chat with an electronic platform offering RFQ, RFS and streaming quotes around the clock, with single-dealer, multi-dealer or hybrid pricing models. Its documentation also lists trade desk tools, compliant chat, client deposit and withdrawal screens, and support for spot, futures, perpetuals, options and multi-leg structures. K33, regulated by the Norwegian Financial Supervisory Authority, runs on Mercury OTC; its live case study reports 200 trading pairs, 8 fiat currencies and OTC trading volume that grew 5x. See Mercury OTC. The published results are on the live K33 case study.

White label

Both vendors offer a white-label route for brokers.

Talos White Label includes a white-label interface and APIs, a customer pricing engine, auto-hedging, a transaction ledger, derivatives support and a margin engine. Talos states it is a SaaS technology platform only and does not provide registrations or satisfy KYC, AML or other compliance obligations [T4]. This is Talos's own disclaimer language. Liquid Mercury's wording is on its own page.

Mercury OTC is described as fully white-labeled for complete client branding, with a client-facing interface, ledger and settlement, and reporting. Liquid Mercury also lists risk controls and audit trails among the platform's built-in features.* A broker should confirm its own registration and compliance needs with any white-label vendor.

Risk and compliance controls

Talos describes safety features such as overfill and fair price protection, duplicate order detection and recovery [T2], price reasonability checks and reconciliation [T8], and sub-account permissions and limits [T6]. It states it is SOC 2 Type 2 compliant per a third-party audit [T1].

Liquid Mercury's Risk Engine runs pre-trade and post-trade checks across spot, perpetuals, futures and options. Pre-trade checks include available balance, available credit, region restrictions, maximum quantity and notional per order, a hyper-marketability check and a theoretical price check. When a limit is breached, new orders are rejected until exposure returns within limits. A kill switch cancels all open orders and blocks new ones, and auto-liquidation flattens an account in aggressive or scheduled mode. See kill switch.
