struct Equities::**Es**## Equities graph.

x axis is probability (x Î [01]), y is equity (y Î [-1 +1]).

Valid between *xLow* and *xHigh*.

Given as two endpoints of a stright line. The low point is X drop point, the high is X cash-out point.

**Public members:**

- float
**r**(float* x*) const

*x* as percent in window. - void
**reverse**(void)
