Does anyone know of open-source code to calculate approximate SPAN futures options margins?
I want to incorporate this into my back-testing code.
I have found enough explanations of how SPAN works to write it myself if necessary but am checking first if there is other code out there.
It needs to be able to operate in the past for back-testing.
