Trading Mechanism on BSE – Order Types & Trade Flow

Trading is no longer people yelling in a ring. It's an algorithm matching electronic orders.

1. The Screen Based Trading System (SBTS)

  • BOLT: BSE On-Line Trading.
  • Blind Order Matching: System matches buyers and sellers based on Price and Time priority. Identities are hidden.

2. Order Types

A. Market Order

  • "Buy Reliance at best price available now."
  • Pros: Guaranteed execution.
  • Cons: Price might be bad (Slippage).

B. Limit Order

  • "Buy Reliance at ₹2500 only."
  • Pros: Price certainty.
  • Cons: No guarantee of execution (if price doesn't fallback).

C. Stop Loss Order

  • "Sell if price falls below ₹2400." (To protect capital).
