I have been doing some retrospective tests with several EAS in MT4.I have realized that the EAS that depend on market volatility begin to lose money around 10/2006.The strangest thing is that this occurs in all pairs.It would be rare for all volatility of the Forex market to disappear in a single month.Is this a problem with MT4 data?Has anyone else noticed the same?Is this with other data sources other than MT4?The Breaking of A Wave Cannot Explain The Whole Sea.
