Order Book Analysis

Understanding the Spread

      Best Ask: $0.72 (500 shares)  ← Lowest seller
      Best Bid: $0.68 (300 shares)  ← Highest buyer
      Spread: $0.04 (4 cents)
      

Tight spread (1-2 cents): Liquid, easy to trade
Wide spread (5+ cents): Illiquid, expensive to trade

Order Book Depth

Look at cumulative size at each price level:

      Price    Cumulative Size
      $0.75    50 shares       ← Thin (easy to move)
      $0.74    200 shares
      $0.73    800 shares
      $0.72    2,500 shares    ← Thick (hard to move)
      

Deep books: Harder to manipulate, more stable prices
Thin books: Easy to manipulate, volatile prices
