Direct Historical Access

If you already know the token (scripcode), you can fetch data directly:

# Using historical_direct with known token
data = nse.historical_direct(
    token='26000',
    symbol='NIFTY 50',
    symbol_type='Index',
    start=start,
    end=end,
    interval='1d'
)

Utility Methods

# Get supported timeframes
print(nse.timeframes())
# Output: ['1m', '5m', '10m', '15m', '30m', '1h', '1d', '1w', '1M']

# Get supported segments
print(nse.segments())
# Output: ['IDX', 'EQ', 'FO']
