How these tools are built
Every calculator states the formula behind it and works through a real example, so you can check the arithmetic instead of trusting a black box. Where a tool uses data, the provider is named and linked on the page, along with how current that data is.
Wherever the maths allows, calculations happen entirely in your browser. Nothing you type is sent to a server or stored, so you can size a position without handing over your account balance.
These tools are for information and education. They are not financial advice and not a recommendation to buy or sell anything. Trading carries risk, including losing more than you put in. Maintained by Joey van Diest; corrections to [email protected].
