Broker Integration Checklist
New Broker Integeration with OpenAlgo - Checklist
✅ OpenAlgo Broker Integration Checklist (Updated)
1. Pre-Integration Checks
Review broker's API documentation (REST, WebSocket, SDKs).
Confirm sandbox or test environment availability.
Identify rate limits, session expiry behavior, reconnection strategies.
2. Authentication
Verify token generation (API Key + Secret or OAuth flow).
Ensure successful login redirects to dashboard or access token endpoint.
Check token refresh or re-authentication mechanism.
3. Funds & Margin
Fetch and normalize:
Available Cash
Collateral
Utilized Margin
Realized & Unrealized P&L
✔ Store in OpenAlgo’s format via /broker/api/funds.py
4. Master Contract Handling
Download and persist contracts for NSE, NFO, BSE, BFO, MCX, CDS, INDEX.
Normalize symbols into OpenAlgo’s format.
Validate
NSE_INDEXandBSE_INDEXsymbols.Validate special characters in symbols (e.g.
M&M).
📘 Refer: Symbol Format Guide
5. Order APIs
Transform broker fields into OpenAlgo common format.
Place Order
Test all Order Types:
MARKET, LIMIT, SL, SL-MKT
Verify across all supported exchanges:
NSE, BSE (Cash), NFO/BFO (F&O), MCX (Commodities), Currencies
Ensure accurate field mapping for symbol, order type, qty, price, product, etc.
Modify Order
NOTE: OpenAlgo does not support order type conversion (e.g., Limit → Market).
Only support modifying Limit orders to other Limit orders (change price, quantity).
Block or log attempts to convert order types.
Cancel Order(s)
Support single order cancellation.
Support bulk cancellation across segments.
Smart Orders (PlaceSmartOrder)
Test across all supported exchanges (NSE, NFO, MCX, CDS, BSE).
Test position size increase → should trigger order for difference.
Test position size decrease → square-off excess quantity.
Test with
position_size = 0→ must square off full open position.If
position_sizeis same as open position → no order should be triggered.Validate against actual values in PositionBook.
6. Order Status & Books
OrderBook
Validate:
Trading Symbol, Exchange, Transaction Type
Price, Trigger Price, Quantity, Product Type
Order ID, Status, Timestamp
Confirm Order Stats: Total Buy/Sell/Open/Rejected/Completed
TradeBook
Ensure mapping of:
Transaction Type, Fill Price, Quantity, Order ID, Fill Time
7. Positions
PositionBook
Map:
Net Qty, Avg Price, LTP, P&L, Product Type
OpenPosition
Fetch open position quantity from broker.
Validate broker → OpenAlgo symbol transform.
Test for all supported exchanges and indices (NSE_INDEX, BSE_INDEX).
8. Portfolio & Holdings
Validate:
Trading Symbol, Quantity, Exchange, Product
Investment Value, Current Value, Absolute & % P&L
Confirm Portfolio stats:
Total Holding Value, Investment Value, Total P&L
9. Market Data APIs
Quotes
Test for all supported exchanges and indices (NSE_INDEX, BSE_INDEX).
Validate special characters (e.g.
M&M).If REST Quote API is not available:
Fetch via broker WebSockets.
Depth (Market Ladder)
Ensure L5 depth is mapped correctly.
If REST Depth API is not available:
Fetch via broker WebSockets.
Historical Data
Test intervals: 1m, 3m, 5m, 15m, 1h, 1d, W, M.
If intraday candles are missing:
Backfill with Quotes API.
Chunk data if date range exceeds limits.
Ensure timestamps are in IST.
10. Final Testing & Edge Cases
End-to-end test: Place → Modify → Cancel → Square Off. Perform complete order lifecycle test
Test partial fills, expired sessions, rejected orders.
Validate consistent error handling and fallback response.
Run integration tests across all supported segments
🔒 Additional Recommended Checks
Ensure secure use of
.envfor API keys.Avoid exceeding rate limits while integerating broker API
