Thanks for your prompt answer! I really don't like beta versions, but I'll give yours a try. Regarding the ASC data, I'll provide you with 2 or 3 files with brazylian data (intraday) so you can see what I'm talking about. Hope you can solve it.... the chat I mentioned are full of people eager to have a backtesting (intraday) at an affordable price and with a friendly interface, and Stockalyze fullfills both! But without importing our data, we can't operate due, as I said, to the unreliability of the brazylian stock exchange intraday data released to foreign services.
Again, thank you for your kindness and for your reply.
