Product overview
What is Capital Companion?
Capital Companion is a trade-planning and review tool for active traders and investors. It combines free position-sizing and risk calculators with saved trade plans, price alerts, outcome tracking, and AI analysis of US stocks. The workflow is designed to record entry, stop, target, position size, and eventual result so a trader can compare the original plan with what happened.
The AI analyst reviews technical indicators, trends, sentiment, and market context, then presents a structured explanation in plain language. Calculators can be used without an account; an account is needed to save a calculation as a trade plan.
How to Use Capital Companion
- Use a position-size or risk calculator to define the trade and its risk before entry.
- Save the calculation as a trade plan with an audit sheet and price alerts.
- After the trade closes, record the outcome and R-multiple.
