Hi jcl, boatman,

This brings up some interesting questions...

From what I read of TickSmooth, a value of 100 would "suppress" by ~99%? Does TickSmooth drop the tick or cause the tick's actual value to be replaced by the EMA value? Besides changing the tick stream, the EMA-introduced delay could of course be problematic also depending on the strategy...

Assuming that Zorro isn't creating these ticks, they're coming from the broker - either directly if DD or as a pass-through from the liquidity provider if NDD? In either case, why then wouldn't they be in the broker's MT4 history? Do brokers regularly "scrub" their history? Is there something in the Terms of Service that say these outliers are the client's problem?

boatman, have you asked the brokers about this & what's going on? Since it's happened at more than 1 broker, is it some sort of "industry standard" that all are using?

Thanks.
