What is High-Frequency Trading (HFT)?
High-frequency trading exploits microsecond execution and rebates with vast order volume.
Indian market context (NSE)
Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how High-Frequency Trading (HFT) shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
High-Frequency Trading (HFT) on Nifty (24,300): backtest includes 9:15 liquidity and expiry-day behaviour; edge on index may vanish outside 10:00–14:30 window.
Reliance Industries perspective
High-Frequency Trading (HFT) on Reliance (₹1,300): liquidity is deep but event gaps dominate — strategy rules need explicit earnings blackout weeks.
Bank Nifty futures perspective
High-Frequency Trading (HFT) on Bank Nifty futures (55,000): high beta suits shorter holds; overnight high-frequency trading (hft) must state NRML risk and gap plan in writing.
