I have tick data on a bunch of securities that I want to backtest some strategies on. The data includes type (bid, ask, or trade), price, volume, date/time, and condition codes stored in csv files. I'm decent with VBA, I don't know any other programming languages and prefer not to learn any, so my plan is to backtest my ideas using VBA and Excel to process the CSV files. Before I reinvent the wheel, what software is out there and recommended that I can program to run backtests on my data? Thanks.
