Why these five
They are the calculations that decide whether an account survives, and the ones traders most often do in their head — badly, under time pressure, with an order ticket open.
Every one runs entirely in your browser. Nothing you type is uploaded, stored on a server, or attached to you. What you last entered stays on your own device so you do not retype it next time.
