Technology has reshaped trading forever. Today’s market moves fast, and traders need tools that can process market data, analyze patterns, and execute trades far quicker than humans ever could. This is exactly where an API for algo trading becomes indispensable.
An API acts as the secure bridge between your strategy code and the broker's trading platform, allowing algo traders to access live market data, place orders, automate trading strategies, and manage portfolios programmatically.
With the CubePlus Trading API, quantitative traders, retail algo traders, and developers get a powerful, ultra-low-latency interface to build and deploy high-performance automated trading systems.
Refer to this document for documentation on how to use the CubePlus API.
What Is an API for Algo Trading?
An API for algo trading is an application programming interface that connects your custom software directly to a broker’s platform. Instead of clicking buttons on a UI, traders use code to:
Fetch real time market data
Backtest using historical market data
Place, modify, or cancel orders
Automate trading strategies
Access account and portfolio data
Execute trades with lightning speed

CubePlus provides a free, developer-friendly trading API that removes friction for traders wanting to integrate trading functionalities into Python, Node.js, Go, or any other environment.

Algo Trading: Why Algorithms Dominate Modern Markets
Algo trading, also known as algorithmic trading, means executing trades based on pre-defined rules programmed into computer systems. These rules can use:
Price and volume signals
Technical analysis indicators
Pattern recognition
Statistical models
Options volatility models
Market microstructure data
The benefits are clear:
Ultra-fast execution
No emotional decision-making
Simultaneous multi-asset trading
Perfect consistency
Ability to utilise micro-opportunities
This is why both retail and institutional traders use APIs to automate trading.
Market Data: The Foundation for Every Trading System
Every trading strategy depends on one thing: market data.
There are two key types:
1. Historical Market Data
Used for backtesting, validating models, and training algorithms.
2. Live Market Data
Used for real-time decision making, especially in high-frequency and options trading.
CubePlus’ Market Data API allows traders to fetch interval-wise OHLCV data through the
/api/mkt-data/chart/interval-data
Example: Fetching 1-minute OHLCV Data
GET https://api.tradejini.com/v2/api/mkt-data/chart/interval-data?from=1685591100&to=1685605354&interval=1&id=EQT_RELIANCE_EQ_NSE
Authorization: Bearer <ACCESS_TOKEN>
This gives open, high, low, close, volume, and (for derivatives) minute-wise open interest change.
Real Time Market Data: Powering High-Speed Strategies
Live market data is critical for:
While historical OHLC is available via REST, **real time ticks **come through the CubePlus streaming SDK (Nxtrad Stream). Algo traders can combine REST + streaming to build full execution engines.
Live feeds help calculate Greeks, implied volatility, spreads, and more—making them essential for serious algo traders.
Algo Traders and Use-Cases: Who Uses These APIs?
Modern algo traders include:
Retail algo trading enthusiasts
Quantitative traders
Options traders
Proprietary desks
Institutional traders
Developers building trading bots
Portfolio managers using systematic models
They use CubePlus API because it offers:
Free access
Ultra-low-latency endpoints
Comprehensive data coverage
Support for equities, F&O, commodities
Full order management features
Automated Trading: Turning Code Into Real Trades
Automated trading systems combine market data + strategy logic + execution algorithms into a fully automated cycle.
CubePlus provides all the core features needed:
Fetch market data
Execute orders
Monitor positions
Calculate margins
Automate exits
Manage multiple strategies
Example: Placing an Automated Market Order
POST https://api.tradejini.com/v2/api/oms/place-order
Authorization: Bearer <ACCESS_TOKEN>
Content-Type: application/x-www-form-urlencoded
symId=EQT_RELIANCE_EQ_NSE&
qty=10&
side=buy&
type=market&
product=intraday&
validity=day
Broker APIs: Why CubePlus API Stands Out
When comparing broker APIs, algo traders look at:
Reliability
Low-latency performance
Security
Documentation quality
Breadth of features
Cost
CubePlus excels because:
The API is completely free
Ultra-fast response times
Strong market data infrastructure
Full support for advanced order types
Easy authentication (OAuth + Individual Token)
Dedicated Relationship Manager for API
Example: Getting an Access Token (2FA Login)
POST https://api.tradejini.com/v2/api-gw/oauth/individual-token-v2
Authorization: Bearer <CLIENT_ID>
Content-Type: application/x-www-form-urlencoded
password=XXXXXX&
twoFa=123456&
twoFaTyp=totp
Comprehensive Data: Scrip Master, Instruments & Symbol Store
Algo traders need detailed instrument-level data (tick size, lot size, exchange token, etc.).
CubePlus offers a full symbol store:
GET https://api.tradejini.com/v2/api/mkt-data/scrips/symbol-store/SECURITIES
Or fetch master groups via version control:
GET https://api.tradejini.com/v2/api/mkt-data/scrips/symbol-store?version=0
This ensures your algo system always trades valid instruments.
Live Market Connectivity: Executing Orders at Lightning Speed
When your algo sends an order, speed matters.
CubePlus provides a highly optimized OMS API to:
Place orders
Modify orders
Cancel orders
Retrieve trade history
Fetch orderbook
Get margin requirements
Example: Modify an Order
PUT https://api.tradejini.com/v2/api/oms/modify-order
Content-Type: application/x-www-form-urlencoded
orderId=123456&
symId=EQT_RELIANCE_EQ_NSE&
qty=100&
type=limit&
limitPrice=2705.50&
validity=day
Example: Cancel an Order
DELETE https://api.tradejini.com/v2/api/oms/cancel-order?orderId=123456
Options Trading Automation: Complex Strategies Made Simple
Options trading requires fast calculations and precise execution.
CubePlus API can automate:
Spreads
Straddles

"symId": "EQT_RELIANCE_EQ_NSE",
"qty": 10,
"side": "buy",
"type": "limit",
"product": "intraday",
"limitPrice": 2700
}
]
}
