SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill solves the critical problem of inconsistent risk management, preventing catastrophic account drawdowns by enforcing disciplined, volatility-adjusted position sizing.

Core Features & Use Cases

  • Risk-Based Sizing: Calculates position size based on account equity and stop-loss distance to maintain a fixed percentage of risk.
  • Concentration Management: Monitors and limits exposure to individual assets, sectors, and correlated groups.
  • Use Case: Use this skill when you have identified a trade setup and need to determine the exact number of shares to purchase while ensuring your total dollar risk remains within your 1-2% policy limit.

Quick Start

Use the position-sizing skill to calculate the number of shares to buy for a 100,000 dollar account with a 50 dollar entry and 47.50 dollar stop at a 1 percent risk level.

FAQPage Schema
How do I calculate position size based on account equity and stop-loss distance?

Position sizing calculates the exact share count by dividing your fixed-fractional risk amount by the distance between your entry price and stop-loss. This ensures your total dollar risk stays within your 1-2% policy limit.

What is fixed-fractional risk modeling in trading?

Fixed-fractional risk modeling is a risk management technique that risks a constant percentage of account equity per trade. It adjusts share counts dynamically based on stop-loss volatility to prevent catastrophic drawdowns.

Can I enforce concentration limits across correlated assets in my portfolio?

Yes, concentration management monitors and limits your exposure to individual assets, sectors, and correlated groups. This prevents over-allocation and enforces portfolio-level exposure analysis.

How do I use volatility-based sizing for trade entries?

Volatility-based sizing adjusts your share count according to stop-loss distance and account equity. You input your entry price and stop level, and it calculates shares to maintain your target risk percentage.

Does position sizing work for accounts with strict 1 percent risk policies?

Yes, position sizing is designed for strict 1-2% risk policies. It calculates the exact number of shares to purchase based on your account equity and stop-loss distance to maintain that fixed percentage of risk.

Why does inconsistent risk management cause catastrophic account drawdowns?

Inconsistent risk management causes drawdowns by failing to adjust share counts for volatility. Without disciplined, volatility-adjusted position sizing, individual trades can exceed safe risk percentages and rapidly deplete equity.
