What you can do

Stock calculator — Work with buy price, sell price, quantity, and target P/L. Switch modes (Smart, Sell, Buy, Qty) to solve for what you need and view change, P/L, and cost at a glance. Leverage — Long or short. Model entry, exit, size, leverage, and target P/L to reason about margin, estimated outcomes, and capital use for isolated linear-style contract math. Position size — Simulate adding to an existing position and see updated average cost, total quantity, and total cost. Profile and basic settings are included. For education and reference only — not financial advice. Markets involve risk; always do your own research.
