Position size calculator

Compatible size connects a market decision to a limit defined before you act. The result does not predict whether the trade will win.

Result

Complete and calculate

No false zero: the result stays empty until the inputs are calculable.

The calculation stays on this device until your explicit action. It will be offered after signup, without automatic saving.

Formula

How the result is calculated

Size = net risk budget ÷ distance between entry and stop.

Rulyx teaching

Framework before outcome

The Rulyx book puts capital preservation before performance. The engine deducts fees from the risk budget only once.

FAQ

Frequently asked questions

Is this size a recommendation?

No. It only translates the inputs and your personal risk limit.

Why do fees reduce size?

Because they are part of the potential loss. Ignoring them would exceed the entered budget.
