Codebase Update: New Features Added in Dhan_TradeHull

General
1

We’ve made several improvements to the Dhan_TradeHull codebase, and here’s a quick overview of what’s new:

  1. 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"
)
  1. 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"
)
  1. 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"
)
  1. 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)

  1. Fetching historical Data for 90 days
    The tsl.get_historical_data() function is now updated to return candle data for the past 90 days.

  2. Strike selection issue fixed
    Strikes for symbols now resolve correctly without mismatch.
