Concentration bias pattern analysis

Concentration Bias Pattern: Manage Your Position Sizing

The Concentration Bias Pattern tool is built for Thinkorswim desktop users who want to understand and control their risk. Are you putting too much of your available cash into a single trade? This tool analyzes your trade history to reveal when your open intraday positions exceed a set percentage of your available cash, helping you spot both emerging and established concentration bias in your trading.

This is not a chart analysis tool. Instead, it focuses on your actual position sizing and risk allocation—tagging days when your position size crosses a customizable cash threshold (default: 24%). Use this insight to improve your discipline, diversify your trades, and avoid the dangers of over-concentration.

For a deeper understanding of risk, try our Range-Based Risk Calculator, which is especially useful for evaluating the risk profile of concentrated positions and low-priced stocks.
