Lecture Notes: Mastering Tape and Level Two Reading for Trading

Introduction

  • Objective: Understanding and improving the ability to read level two data in trading.
  • Challenges: Initial difficulty in connecting changing numbers to market events and future predictions.
  • Importance: Reading level two and tape provides a trading edge.

Setup and Importance of Level Two

  • Markets: Applicable to various markets (e.g., S&P 500, Bitcoin, commodities, individual stocks).
  • Broker Platforms: Different brokers have different default displays for level two.
    • E*TRADE: Cleaner display for visualizing market depth.
    • Thinkorswim: Not user-friendly for over a decade.*

Understanding Level One vs. Level Two

  • Level One: Shows best bid and offer.
    • Example: Bid $505.20, Offer $505.21.
  • Level Two (Market Depth): Shows market makers, prices, and share sizes.
    • Example: NSDQ with order size 600 shares, 1-cent spread.

Reasons for Selling on the Offer

  1. Iceberg Orders: Selling a larger position hidden behind the displayed order.
  2. Rebates: Exchanges like NASDAQ pay small rebates for selling on the offer.
  3. Best Price: Achieving the best price, though it requires patience.

Visualizing Market Depth

  • Color Coding: Differentiates between price tiers.
    • Example: Green for first level, Red for second.
  • Purpose: Easier differentiation of buyer and seller stacks, indicating supply and demand.

Time and Sales Pairing

  • Purpose: Provides context to whether orders are being placed or are static.
  • Focus: Primarily on the ask price, with peripheral monitoring of tape for red (bid) and green (offer).
  • Hidden Sellers: Identifiable when large buy orders do not move the price.

Trading and Market Dynamics

  • Indicators: Level two alone is not an indicator; must be paired with chart patterns.
  • Context: Large sell orders near resistance points (e.g., whole dollars) are common.
  • Trader’s Insight: Experience and intuition play a crucial role in interpreting level two data.

Practical Application

  • Visualization: Changing level two display colors for clarity.
  • Pairing with Tape: Ensures complete market picture.
  • Interpretation: Recognizing patterns, such as churning, that indicate resistance.

Conclusion

  • Steps to Mastery:
    1. Change color settings for better visualization.
    2. Pair level two with time and sales for context.
    3. Train focus on the most informative aspects: ask price, bid spread, and large orders.
