software for backtesting

Hi I was wondering what software people use to backtest the data. I'm new to algo trading, but been trading discretionary for a number of years. Currently I am using forex strategy builder to build the strategy and test it over the last 50,000 bars. I got a larger range of data dating from the last 10 years but the software is refusing to open the file (it's 190 mb). Metastock is also refusing to convert the file into one chart since it is over the 65000 rows. So essentially I want to backtest a strategy over an unlimited rows over data.

Alternatively since I am mainly using the 5 and 15 mins time frame is there a software where I can convert my 1 mins rows into larger time frames? It would significantly compress the data making the rest of the software compatible with it
