I know Walk Forward will be part of the optimisation tool in a next version of prorealtime. I don’t know when it will be released, but it should be next year IMO. Since WFO is a complex (and more efficient) way of doing optimisation, I had many talks with PRT engineers about this feature to be at the same time user friendly and with accurate and readable results for the complete range of customers the platform has.
Be sure I will talk about it as soon as I have access to beta version of this tool!
