While viewing a security or your portfolio, you can access the Price/Yield calculator.
The calculator
will auto-populate some fields based on the security or portfolio you are viewing.
The P/Y page calculates either price based on expected yield, or expected yield based on price.
Yields can be either bond-equivalent or mortgage yields.
You can also go directly to the Price/Yield
calculator from the Analytics page and enter the parameters for the calculation.
