Market data feeds: from the exchange to every screen, live

Native feed handlers for the exchanges you trade, full depth, market status that follows the venue, and a hot standby that takes over on its own.

In short

ZagTrader connects natively to exchange and vendor feeds and turns them into live prices, depth, trades and charts on every screen and API. Market status and halts follow the exchange, the instrument list keeps itself current, entitlements control who sees what, and a hot standby keeps data flowing if a server fails.

Connects to: Native exchange protocols, FIX market data, vendor feeds and venue APIs
Delivers to: Trading screens, mobile apps, client APIs and the back office
Stays up with: A hot standby that takes over automatically, plus gap recovery from the exchange

What your market data team gets

One feed layer for every venue, built so prices never wait.

Native exchange feeds

Direct handlers for the protocols exchanges publish, plus FIX market data, Bloomberg end-of-day prices and venue APIs, including digital-asset exchanges.

See the details

Full depth, trades and charts

Best bid and offer, depth by order and by price, indicative auction prices, time and sales and intraday charts, all from the same stream.

See the details

Market status that follows the venue

Pre-open, open, close and trading halts are applied the moment the exchange publishes them, with an announcement to users.

See the details

An instrument list that maintains itself

New listings are created from the feed. Lot size, tick size, price limits and ISIN stay in step, and renamed symbols are matched automatically.

See the details

Market data as a revenue line

Control access per user, market and instrument, and sell live prices and full order book as subscription packages billed to the client account.

Hot standby, not cold failover

A standby engine stays current on the same data and takes over within seconds if the primary stops. No replay, no reload.

Everything in the market data layer

The full capability set, in plain language.

Capability	What you get
Exchange feeds	Native handlers for the main exchange protocols, including ITCH, MITCH, Euronext OPTIQ, FAST and X-Stream, with each venue running in its own isolated process.
FIX and vendor data	FIX market data from venues and liquidity providers, Bloomberg end-of-day prices on a schedule, NASDAQ Data Link, and REST and WebSocket APIs from digital-asset venues.
Prices and depth	Best bid and offer, last trade, day statistics and price limits, with full depth by order and by price and indicative opening and closing auction prices.
Trades and ticks	Every trade with time, price, quantity and aggressor side, kept as tick history for time and sales.
Charts	Intraday chart bars built from the live feed, so charts on every front end match the prices traders see.
Market status and halts	Market sessions and instrument suspensions follow the exchange automatically, so order entry respects the real state of the market.
Instrument master	New instruments created from the feed, or listed by hand if you prefer. Static fields stay in step with the venue, and venue news becomes platform announcements.
Your own venues	Prices formed on ZagTrader matching engines and synthetic instruments reach the same stream, so a screen shows one feed wherever a price was made.
Streaming	Live streaming over TCP and secure WebSocket to trading workstations, web portals, mobile apps and client APIs, with updates bundled per instrument for smooth delivery.
Entitlements	Access checked at the stream itself, per user, per market and per instrument, using an allow-list or a block-list model.
Subscriptions and billing	Package live prices and full order book into tiers, manage requests and approvals, and bill subscription fees through the client ledger.
Resilience	Hot standby with automatic take-over, gap recovery from exchange replay services, same-day restart without reprocessing, and self-restarting components.
Scale	One process per venue feed, parallel processing that keeps each instrument's updates in exchange order, and extra streaming engines that fan out to more users.
Monitoring	A heartbeat for every feed, connection and engine, and a browser console showing markets, instruments, connected users and standby status.

Frequently asked questions

Can ZagTrader connect to our exchange's feed?

Very likely. We handle the main native exchange protocols, FIX market data, vendor feeds and venue APIs. Tell us your venue and we will confirm the route.

Do live prices reach our mobile app and APIs too?

Yes. The same stream feeds trading workstations, web portals, mobile apps and client APIs, so every channel shows the same price at the same time.

What happens if a market data server fails?

A hot standby holds the same live data and takes over automatically when the primary stops. Feed handlers recover any missed messages from the exchange's replay service.

Can we control who sees full market depth?

Yes. Entitlements are enforced at the stream, per user, per market and per instrument, so each user receives only the data they are allowed to see.

Can an exchange or broker sell market data through ZagTrader?

Yes. Package live prices and full order book as subscription tiers. Clients request them, you approve, and fees are billed through the client account.

Do we have to maintain the instrument list by hand?

No. New listings can be created from the feed, static details stay in step with the exchange, and renamed symbols are matched automatically. You can still list by hand if you prefer.
