Howto figure out, that I requested historical data for an invalid symbol?

[Dierk Droth]

Hi,

There seems to be no way to figure out if a symbol name is valid.

On requesting historical data for an invalid symbol, none of the appropriate callbacks (OnBarReceived, OnBarChanged) is called.

Is there any other callback called ? What's the recommended way to figure out that I just requested historical data for an invalid symbol ?

I haven't tried it myself yet, but there is a new function called IsValidSymbol. I believe you need at least the 7.7 release candidate for it, but I don't recall when exactly it was added.

Genspoo is correct. If it is not in there now, it will be in the version that is out later this week.

Thanks. I'll give it a try.
