Core Concepts

Bid-Ask Spread
Beginner

The spread is the cost of immediately buying or selling. Wider spreads mean higher execution cost and lower liquidity.

Order Book Depth
Beginner

Depth shows how much quantity is available at each price. Thin depth means prices can move sharply on small trades.

Market Impact
Beginner

Large orders in illiquid stocks can move the market against the trader, increasing average purchase or sale price.

Indian Market Context

Small-cap and mid-cap stocks on NSE can be very illiquid, with 10-20% daily moves caused by modest order flow.
