Low-latency WebSocket systems for live prices, order updates and notifications — with reconnection, scaling and back-pressure handled properly.
Low-latency WebSocket systems for live prices, order updates and notifications — with reconnection, scaling and back-pressure handled properly.
Ticks, depth and order updates in real time.
Resilient reconnection and resubscription.
Handles bursts without dropping the client.
Broadcast to thousands of concurrent clients.
Everything you need to build, automate and scale your trading technology.
Broker API integration services — Zerodha, Angel One, Upstox, Dhan, Fyers, Binance and more for live market data, order execution and account synchronization.
REST API development services — secure, versioned, well-documented REST APIs with authentication, rate-limiting and scalability for fintech and trading apps.
Custom API development & integration services — payments, KYC, SMS/WhatsApp, data providers and internal systems integrated into a secure, unified API layer.
Trading WebSockets are binary, high-frequency and unforgiving. Broker sockets pack quotes into fixed-offset structures where a five-level order book sits at a known byte position, and a mode change alters the packet length, so a parser written against one mode silently reads zeros in another. We write parsers against the published packet spec and validate them against live traffic before anything depends on them.
Throughput is the second problem. Thousands of ticks a second, hundreds of connected clients, and each client interested in a different subset means broadcasting everything to everyone is not an option. We keep a subscription map per connection, coalesce updates so a symbol that ticks fifty times a second is sent at a sane cadence, and drop slow consumers rather than letting them back-pressure the whole hub.
Reliability comes from heartbeats, exponential-backoff reconnection, resubscription of the previous symbol set on reconnect, and a warm cache so a client that connects mid-session sees prices immediately instead of an empty screen.
Yes. A single hub can normalise upstream sources and fan out to many front ends over one socket per client, which is both cheaper and more consistent than each site holding its own broker connection.
Automatic reconnect with resubscription, plus a REST snapshot on connect so the app is never blank while the socket re-establishes. We also avoid protocol settings that behave badly on Indian mobile carriers.
Both, plus SSE where a one-way stream is enough. Raw WebSocket is usually the right answer for tick data because the framing overhead matters at volume.
A single-source integration with a fan-out hub starts around Rs 25,000; multi-source with failover and depth normalisation is higher.
