Extended Hours Trading Pattern: Understand Your After-Hours and Premarket Activity
The Extended Hours Trading Pattern tool is designed for Thinkorswim desktop users who want to uncover and address a tendency to trade outside the standard 9:00 AM to 4:00 PM market session. Are you frequently placing trades in the premarket (4:00 AM – 9:29 AM) or after-hours (4:01 PM – 11:59 PM)? This tool analyzes your trade history to reveal patterns of extended hours trading, helping you improve discipline and manage risk.
This is not a technical charting tool. Instead, it focuses on your actual trading decisions—specifically, trades executed before the market opens or after it closes. Use these insights to avoid impulsive trades during less liquid periods and maintain a balanced approach.
For a complete view of your trading discipline, explore related tools like the Scalping Behavior Pattern and the Symbol Attachment Bias.
