Capabilities

One standard API surface. Every capability your strategy needs.

Our XTS API exposes the full surface most Indian algo and strategy platforms expect, so connecting an external tool is usually a configuration step, not an integration project. Tell us which tool you use and we’ll walk you through the exact setup.

Order placement

Place, modify, cancel and bracket orders across equity, F&O, currency and commodity. Full timing and risk controls.

Market data

Live quotes, depth, OI and historical candles. REST polling for prototypes, WebSocket streaming for production.

Backtesting & paper trade

Wire your strategy to historical data first, then to a paper account, then to live, with the same code path each step.

Strategy builders

If your platform of choice is no-code, low-code, Python-native or visual flow, the XTS surface fits all four.

Copy trading

Lead, follow or aggregate trades across multiple accounts. Useful for prop desks, partner desks and family pools.

Cross-broker aggregators

Tools that target multiple brokers at once treat XTS as a first-class citizen. Toggle us on, off, or alongside.

Self-hosted clients

Prefer to run your own infra? Open-source XTS clients exist in Python and the official SDK is open and forkable.

Dealer / sub-account API

For prop desks, partners, and HNIs running multiple sub-accounts under one parent. Same API, dealer scope.

Tell us your platform →Email algo@acagarwal.com with the tool name and we’ll send back a setup guide tailored to it.

Developer experience

Your first order, in under ten lines.

The official Symphony XTS Python SDK is pip-installable, MIT-licensed, and mirrors the REST interface 1:1. If you know Python, you know our API.

REST + WebSocket (binary & JSON modes)
Interactive API for orders & positions
