Trading Calculator for Risk Management and Reward-Risk Ratio by PowerShell

I created a PowerShell-based trading calculator tool to enforce disciplined risk management. The motivation stemmed from lacking discipline in following the 2% risk management rule, which resulted in significant losses.

Features

The calculator performs four main computations:

1. Risk % — Calculates risk percentage against total fund using shares, entry price, target price, and stop price
2. Reward Risk Ratio — Computes RRR from entry, target, and stop prices
3. Stop Price — Determines appropriate stop price based on total fund, shares, entry price, and desired risk percentage
4. Shares — Calculates optimal share quantity based on fund, entry/stop prices, and risk tolerance (this is the most useful feature)

Code Structure

The script uses:

• WPF (Windows Presentation Foundation) for the GUI
• Input validation to ensure entry prices exceed stop prices
• Mathematical rounding for precision
• Button controls for “Run” and “Reset” operations

Usage

Users execute the tool via PowerShell on Windows machines. Desktop shortcuts can be created for quick access.

The complete, working script is available on GitHub at mwu17/PowerShell/TradingCalculator.ps1.
