Hi,
Thanks for your prompt reply.
Used Realstocksdata, but their data is delayed and you will find candles missing. You won't find missing candles corrected in next days' backfill, they remain missing forever. They provide only 6-month intraday data. Some symbols are only either cash or FnO, not both.
Rest of providers are providing either cash or FnO.
Looking for combined data provider (who can provide both Cash and FnO segment, without delay, realtime and EOD).
