We will add the ability to access the timeframe from the cAlgo API soon.

For the time being you might be able to use a workaround method. Please see this sample code: /forum/calgo-reference-samples/163

I am trying to use the System.Data.SqlClient namespace but it gives me an error.  It says the namespace does not exist and asks if I am missing an assembly.

Do you know whats wrong?
