I am facing an issue where I am unable to fetch live market data (LTP) or historical candle data for NIFTY 50 and other indices using the SmartAPI.

Issue Summary:

• I used the correct token for NIFTY 50 (99926000) from your Scrip Master file (https://margincalculator.angelbroking.com/OpenAPI_File/files/OpenAPIScripMaster.json).
  {"token":"99926000","symbol":"Nifty 50","name":"NIFTY","expiry":"","strike":"0.000000","lotsize":"1","instrumenttype":"AMXIDX","exch_seg":"NSE","tick_size":"0.000000"},
• I tried fetching both LTP and historical data but did not receive any response.
• I also tried changing the exchange from NSE to NFO, but it did not resolve the issue.

Steps I Tried & Results:

1️⃣ Fetching LTP for NIFTY 50

ltp_data = smartApi.ltpData("NSE", "99926000")
print("LTP Response:", ltp_data)

• Expected Outcome: It should return the last traded price (LTP) for NIFTY 50.
• Actual Outcome: No data received / Empty response.

2️⃣ Fetching Historical Data for NIFTY 50 Spot (NSE)

historicParam = {
    "exchange": "NSE",
    "symboltoken": "99926000",
    "interval": "ONE_HOUR",
    "fromdate": "2025-03-01 09:15",
    "todate": "2025-03-03 15:30"
}

data = smartApi.getCandleData(historicParam)
print("Historical Data Response:", data)

• Expected Outcome: It should return historical OHLC candle data for NIFTY 50.
• Actual Outcome: No data received / Empty response.

3️⃣ Fetching Historical Data for NIFTY Futures (NFO)

historicParam = {
    "exchange": "NFO",
    "symboltoken": "99926000",
    "interval": "ONE_HOUR",
    "fromdate": "2025-03-01 09:15",
    "todate": "2025-03-03 15:30"
}

data = smartApi.getCandleData(historicParam)
print("Historical Data Response:", data)

• Expected Outcome: It should return historical OHLC candle data for NIFTY Futures.
• Actual Outcome: No data received / Empty response.
