About Stopline

Why Stopline exists

Most trading calculators are cluttered, slow or built to sell you something. Stopline is a set of clean, free risk tools for traders who want to plan a trade before they place it: how big, where to stop, what it needs to win, and how much room an account has. There is no signup for any tool.

How the calculators work

Every calculator uses standard, published formulas, and each page shows the formula and a worked example. The numbers you enter are processed in your browser. They are not sent to a server. Progress such as streaks and journal entries is stored in your own browser.

What these tools are not

Stopline is educational. It does not know your full situation, it does not model slippage, taxes or fees unless a tool says so, and results are only as good as the inputs. Nothing here is financial, investment or legal advice, and trading involves risk of loss. Read the terms and disclaimer.

Who makes it

[Add two or three sentences about who you are and why you built this, for example your trading experience and what you wanted a calculator to do. Real names or credentials build trust with readers and reviewers.]
