Dataset catalog | NIFTY lab

3 datasets: only the data the strategies read. Files, sizes and date ranges are measured from the data on disk each time this page loads. Sizes are file sizes on disk; dates are the first and last day found inside the files.

Inputs: the files listed here are the real market data on disk, as they were recorded - data/fyers/options_daily_nse/NIFTY/ (NSE daily bhavcopy), data/fyers/options_1m_fyers/NIFTY/ (Fyers 1-minute option prints) and data/fyers/index/ (Fyers index candles). Every size, count and date on this page is measured from those files; nothing here is modelled or estimated.
