hi i keep on recieving the following warning every now and agian during the trading day. "WARNING THIS APPLICATION IS HAVING PROBLEMS KEEPING UP WITH THE REAL TIME DATA FLOW". I have created a local file of historical intra day data (30min) for 200 securities from quotecenter data on demand, then copyed the data to my local file using the downloader and then requested this file to recieve real time data. everything works ok, but i find that if i dont close the file server mid trading day to store the data to the local file and then reopen the file server for the rest of the day i get the above warning, if i am not around to close ms when i get the warning i land up loosing data. i have gone to online help and have had no joy, so if there are any suggestions they would be greatly appreciated :D thanks byron
