I have used DataBull for about two years at a fee of USD 100 and it worked fine. It even gave me "ticks" for today's share development. Today I am rather frustrated. Neither "DataBull", nor its owners "Ditec software" seems to answer to support request. 8 days without answer is too long, especially when website claims "usually within 24 hours" ! To purchase a software with no support, - can be risky business. I cannot recommend it anyh longer.
