if I begin a download about 21:00 o'clock (german time) with this request:
"HTT,XGU15,20150619 020000,20150917 230000,0,000000,235959,1,HTT,2500\r\n"

i got the message
"HTT,E,Invalid symbol.,\r".

Some hours before it has still functioned.
I dont understand this. Is there an explanation for that?

My apologies for the delayed response.

Our history servers will currently sometimes return an invalid symbol error message if there was no data available for the time period requested. We are working on addressing this problem.

As a workaround, you can safely ignore this error message and assume that the request simply returned zero datapoints.
