DhanHQ — Indian Market Trading Skill
Setup
Stable install:
pip install dhanhq
Use the current SDK branch when you need newer v2 capabilities such as 200-level depth or the latest helper coverage:
pip install --upgrade dhanhq
Minimal initialization:
from dhanhq import DhanContext, dhanhq
dhan_context = DhanContext("YOUR_CLIENT_ID", "YOUR_ACCESS_TOKEN")
dhan = dhanhq(dhan_context)
Environment-variable setup:
import os
from dhanhq import DhanContext, dhanhq
dhan_context = DhanContext(
os.environ["DHAN_CLIENT_ID"],
os.environ["DHAN_ACCESS_TOKEN"],
)
dhan = dhanhq(dhan_context)
If generating scripts for this repo, prefer:
from scripts.dhan_helpers import get_client
dhan, dhan_context = get_client()
Safety Rules — Always Enforce
- Confirm before placing live orders.
- Show a readable order preview before execution.
- Default to
LIMITorders unless the user explicitly wantsMARKET. - Warn when notional exceeds
Rs. 50,000. - For F&O, validate lot size before placement.
- Never use
CNCorMTFfor F&O, commodity, or currency segments. - Never hardcode credentials in generated code.
- Ask for confirmation before
modify_order,cancel_order,kill_switch, or any multi-leg live execution.
Access Checks Before Live Use
Before using the account for live work, verify:
- Access token is valid.
dhan_login.user_profile(...)orGET /profileshows the needed account setup.dataPlanis active for quote/history/feed/option-chain use.- Static IP is configured for order placement, order modification, order cancellation, super orders, and forever orders.

High-Value Gotchas
- The SDK wraps HTTP responses as
{"status": "success"|"failure", "remarks": ..., "data": ...}. Response shapes vary by endpoint — success payloads differ significantly (arrays, flat objects, nested dicts) depending on the API. - Repo helpers add a normalization layer. Fields like
ce_ltp,ce_oi,ce_ivare repo-defined names — not raw Dhan field names. intraday_minute_data(...)is the current SDK method. Do not referencehistorical_minute_data().- Historical timestamps are epoch values. Convert them explicitly.
- The SDK currently validates
expiry_codewith[0, 1, 2, 3], but Dhan's v2 annexure documents0,1,2. Prefer the documented values unless Dhan updates the API docs. - Quote APIs are rate-limited to
1 request/sec. - Option-chain REST data is keyed by strike string under
data["oc"]. Use repo helpers for analysis-friendly rows. - Market orders via API are currently converted by Dhan into limit orders with MPP.
- Order placement APIs require static IP whitelisting.
- Trading APIs are free for Dhan users; Data APIs require an active data plan.
- Lot sizes and freeze quantities change. Treat hardcoded values as fallback only.

Core Patterns
1. Check account access before data calls
from dhanhq import DhanLogin
dhan_login = DhanLogin("YOUR_CLIENT_ID")
profile = dhan_login.user_profile("YOUR_ACCESS_TOKEN")
print(profile["dataPlan"])
print(profile["dataValidity"])
2. Fetch historical data with epoch conversion
data = dhan.historical_daily_data(
security_id="2885",
exchange_segment=dhanhq.NSE,
instrument_type="EQUITY",
from_date="2024-01-01",
to_date="2024-12-31",
)
if data["status"] == "success":
candles = data["data"]
timestamps = [dhan.convert_to_date_time(ts) for ts in candles["timestamp"]]
3. Normalize option-chain data for analysis
from scripts.dhan_helpers import fetch_chain_df, find_atm_row
chain_df, spot = fetch_chain_df(dhan, under_security_id=13, expiry="2025-03-27")
atm = find_atm_row(chain_df, spot)
print(spot)
print(atm["strike"])
print(atm["ce_security_id"], atm["ce_ltp"])
4. Margin check before live order placement
from scripts.dhan_helpers import check_margin
margin = check_margin(
dhan,
security_id="2885",
exchange_segment=dhanhq.NSE,
transaction_type=dhanhq.BUY,
quantity=10,
product_type=dhanhq.CNC,
price=2450.0,
)
print(margin["sufficient"], margin["total_margin"], margin["available_balance"])
5. Live market feed
from dhanhq import MarketFeed
instruments = [
(MarketFeed.NSE, "2885", MarketFeed.Ticker),
(MarketFeed.NSE_FNO, "49081", MarketFeed.Full),
]
feed = MarketFeed(dhan_context, instruments, "v2")
feed.run_forever()
print(feed.get_data())
Rate Limits
| API Category | Per Second | Per Minute | Per Hour | Per Day |
|---|---|---|---|---|
| Order APIs | 10 | 250 | 1000 | 7000 |
| Data APIs | 5 | - | - | 100000 |
| Quote APIs | 1 | Unlimited | Unlimited | Unlimited |
| Non-Trading APIs | 20 | Unlimited | Unlimited | Unlimited |
Reference Files
Dhan APIs cover execution, quotes, OHLC, option chain, and portfolio. For fundamental data (PE, EPS, revenue), technical indicators (RSI, MACD), or shareholding patterns not available via Dhan, use ScanX — see references/scanx-data.md.

Data API Subscription Invalid
If the user gets DH-902 or 806:
- Log in to
web.dhan.co - Open
My Profile->Access DhanHQ APIs - Verify that
dataPlanis active - Activate the Data API plan if needed
- Generate a fresh access token
- Re-test with
ticker_data()orohlc_data() - If order APIs still fail, check static IP separately
