Everything you need to know about the Gato platform
Quick answers on OMS, EMS, FIX connectivity, pre-trade risk, regulatory reporting, onboarding, and the rest of the Gato module suite. Each answer links to the relevant product page if you want to go deeper.
Gato Systems builds the trading, risk, compliance, and operations infrastructure that broker-dealers, proprietary trading firms, hedge funds, clearing firms, and fintech platforms run their businesses on. Because the platform spans the full trade lifecycle, from order capture and FIX connectivity through pre-trade risk controls, allocations, reconciliation, corporate actions, and regulatory reporting, most questions we receive fall into a handful of recurring themes.
The answers below are grouped accordingly: trading and execution (OMS, EMS, FIX versions, asset-class coverage), risk and compliance (SEC Rule 15c3-5 market access controls, FINRA Rule 4210 margin, CAT and CAIS reporting), and operations and data (onboarding, funding, reconciliation, analytics). Each answer links to the relevant module or technical guide if you need more depth than a short answer allows.
If a question is not covered here, the fastest path is a short scoping conversation: asset classes traded, venue and clearing relationships, current systems, reporting obligations, and daily order volumes are usually enough to outline a phased deployment.
Trading & Execution
What is an Order Management System (OMS)?
An OMS is the system of record for the full order lifecycle, order capture, routing, allocations, position keeping, and post-trade workflow. gHub is Gato's multi-asset OMS and FIX connectivity hub, used by broker-dealers and prop firms to consolidate flow across venues, brokers, and asset classes.
What is the difference between an OMS and an EMS?
An OMS owns the order lifecycle and books of record; an EMS focuses on execution, algos, smart order routing, market data, and trader productivity. Many firms run both. gHub is the OMS layer and gTrader Suite is the EMS/trader workstation; they're designed to interoperate.
Does Gato support FIX 4.2, 4.4, and 5.0 connectivity?
Yes. gHub provides certified FIX connectivity to major US and global venues, brokers, and clearing firms across equities, options, futures, and FX. We support FIX 4.2, 4.4, and 5.0 SP2, with managed sessions, drop-copies, and conformance testing.
Which asset classes does the gTrader Suite cover?
gTrader Suite supports US and international equities, listed options, futures, and FX, with extensible adapters for additional asset classes. It ships as both a desktop trader and a browser-based workstation.
Risk & Compliance
How does Gato support SEC Rule 15c3-5 (Market Access Rule) compliance?
gPrecision provides pre-trade and at-trade risk controls, credit limits, fat-finger checks, restricted lists, position and exposure limits, and kill-switch capability, required by SEC 15c3-5. Controls run in-line with order flow at sub-millisecond latency.
Does Gato handle CAT, OATS, and Blue Sheets reporting?
Yes. gReg automates Consolidated Audit Trail (CAT) reporting, large trader reporting, Blue Sheets, and other US regulatory submissions, with full lifecycle tracking, reject management, and an auditor-ready archive.
Can pre-trade risk run in real time without slowing execution?
Yes. gPrecision is built for in-line, sub-millisecond risk checks so controls don't become a latency tax. Limits, exposures, and kill-switches are evaluated against live positions before each order reaches the venue.
Onboarding, Data & Operations
How does Gato automate client and account onboarding?
gFlow digitizes the full onboarding journey, KYC/AML, account opening, entitlements, and approvals, replacing email, PDFs, and spreadsheets with a configurable workflow engine and full audit trail.
What does gPure handle for corporate actions?
gPure is Gato's corporate action system. It tracks events, collects and validates client elections, maintains event calendars and archives, and keeps a timestamped audit record. A client portal keeps investors informed, so less of the notification and election risk sits with your operations team.
What is gNexus used for?
gNexus is a centralized reporting portal. Teams access, monitor, and manage operational and financial reports through role-based dashboards, with multi-level review and approval workflows and administrative controls that enforce policy and accountability.
What does gView do for client fund movements?
gView automates end-to-end fund movements and controls. It routes approvals, executes the payment including NACHA file generation, SFTP delivery, and GL entries, then writes timestamped, exportable audit reporting with configurable alerts and reminders.
How does gClarity handle fees, commissions, and P&L?
gClarity calculates, reconciles, and reports trade fees, commissions, adjustments, positions, and P&L. It maps execution data to the right firm, MPID, account, and group, applies configurable fee logic, validates results against clearing-side records, and delivers audit-ready reports and exports.
Platform, Deployment & Support
How is the Gato platform deployed, cloud, on-prem, or hybrid?
Gato modules run in private cloud, on-prem, or hybrid configurations. Most clients deploy in a co-located environment near their execution venues for latency-sensitive workflows, with management planes in the cloud.
Do I have to adopt the full suite or can I start with one module?
You can start with a single module, gHub, gPrecision, or gReg are common entry points, and expand later. Every module reads and writes the same order, account, and transaction record and integrates over shared REST, streaming, and FIX APIs, so adding a module is incremental rather than a migration.
Does Gato offer APIs and developer documentation?
Yes. Gato exposes REST, streaming, and FIX APIs across the suite. The developer portal covers authentication, schemas, sandbox credentials, and integration patterns.
Who is the Gato platform built for?
Broker-dealers, proprietary trading firms, clearing firms, and asset managers that need institutional-grade OMS, EMS, risk, and regulatory infrastructure without stitching together legacy point solutions.
