Key Points to Understand Percentage in Book Depth Data:

  1. Bid Percentage: Shows the percentage of buyers bidding to buy the stock.
  2. Ask Percentage: Shows the percentage of sellers asking to sell the stock.
  3. Depth Percentage: Shows the percentage of buy or sell orders relative to total trading volume.

If a stock’s Book Depth Data shows:

  • Bid Percentage: 30%
  • Ask Percentage: 70%

This indicates:

  • 30% of traders are bidding to buy.
  • 70% of traders are asking to sell.

  • timestamp: Shows the exact date and time (2024-01-18 00:00:12) when this snapshot of the order book was captured. All rows have the identical timestamp, indicating this is a single snapshot of the order book at one moment in time.
  • percentage: Represents price levels relative to some reference price (likely the mid-price). Negative values (-5 to -1) represent bid price levels below the reference price, while positive values (1 to 5) represent ask price levels above the reference price.
  • depth: Shows the cumulative quantity of orders at each price level. For bids (negative percentages), the depth decreases as we move closer to the reference price. For asks (positive percentages), the depth increases as we move away from the reference price.
  • notional: Represents the monetary value of the orders at each price level (price × quantity). This is expressed in scientific notation.

According to the provided explanation about Book Depth Data:
• The negative percentage values show bid percentages (buyers)
• The positive percentage values show ask percentages (sellers)
• The depth column shows the quantity of orders at each percentage level
• The notional column provides the monetary value of those orders

the “depth” in this bookDepth data is not exactly the same as what’s typically called “depth” in a standard orderbook.

• The “depth” column appears to show the cumulative quantity of orders at each price level. This means at each percentage level, the number represents the total sum of all orders from that level up to the most extreme level on that side
