We’ve made several improvements to the Dhan_TradeHull codebase, and here’s a quick overview of what’s new:
- Long-term historical data
You can now pull multi-year data easily using:
data = tsl.get_long_term_historical_data(
tradingsymbol="NIFTY",
exchange="NSE",
timeframe="5",
from_date="2022-01-01",
to_date="2025-12-03"
)
- Sector-wise historical data (Intraday)
This helps when analysing broader market sectors.
data = tsl.get_historical_data("NIFTY 100", "NSE", timeframe="1", sector="YES")
data = tsl.get_long_term_historical_data(
tradingsymbol="NIFTY 100",
exchange="NSE",
timeframe="5",
from_date="2022-01-01",
to_date="2025-12-03",
sector="YES"
)
- Expired options data
You can now fetch historical option data even after expiry.
data = tsl.get_expired_option_data(
tradingsymbol="RELIANCE",
exchange="NSE",
interval=1,
expiry_flag="MONTH",
expiry_code=1,
strike="ATM",
option_type="CALL",
from_date="2024-10-10",
to_date="2024-11-10"
)
- Market depth data for multiple instruments
Useful when you need full-depth snapshots for different symbols.
symbol_list = [
("RELIANCE", "NSE"),
("NIFTY 09 DEC 26000 CALL", "NFO"),
("NIFTY 09 DEC 25500 PUT", "NFO")]
depth_data = tsl.full_market_depth_data(symbol_list)
for key, depth_client in depth_data.items():
bid_df, ask_df = tsl.get_market_depth_df(depth_client)
-
Fetching historical Data for 90 days
Thetsl.get_historical_data()function is now updated to return candle data for the past 90 days. -
Strike selection issue fixed
Strikes for symbols now resolve correctly without mismatch.
