I have code writen in Pascal-like pseudo code with cca 500 rows. The original code is complex algorithm for display trend lines in financial chrts. I want to change the code so will be add numeric walues of the trend lines to original price data. That could to be about 5 - 10 columbs. What programming language will be the best for fast working and also for cca 400 markets and with possibility to work in real time too? .. and what will be the best type of database software (better free). See the attachement.
