"Historical Market Data Service error message:Time length exceed max"

Hi,

I am using my test (demo) account to do some testing. I tried to request 63 days of daily historical market data of IBM stock, but I got the error "Historical Market Data Service error message:Time length exceed max". Does it make sense? Is it because I am not using production account? How to solve this?

many thanks!
