Walk-forward-tested forex methods?

I have not had much luck finding Forex trading methods that survive walk-forward testing (using Amibroker). Are there any publicly disclosed systems that are profitable, and that ideally have available Amibroker AFL code?

I’m looking for something like Larry Connors “High Probability” trading methods, but for Forex instead of ETFs. It would be great to reproduce the results of a public system, and use that as a base for other ideas.
