Editorial interest 84/100 Selection signal · not a rating of the site

A no-sign-up trading toolkit that calculates position size, explains market terms, and records what happened after the trade.

Landing page captured for the 2026-09-03 issue.

Field notes

The calculator derives position size from an account size, risk percentage, entry, and stop, with an optional take-profit value for risk/reward. A visible example turns a $100 risk limit and $2 stop into 50 shares, while the journal is described as calculating win rate, average R, and drawdown on the user's device. The surrounding reference layer includes 135 dictionary entries, six guides, and 24 market-history topics covering 1987–2025.
