64 bytes per quote x 500,000 bars (default max # saved) = 32 MB for a single quote array (e.g. Open)
For OHLCV: 32 MB x 5 = 160 MB 10 x 160 MB = 1.6 GB 20 x 160 MB = 3.2 GB 500,000 / 1440 minutes-per-day = @ 347 days So, depending on the specifics of computer memory, which quotes you are using, etc., you could backtest on a portfolio of something like 10 - 20 symbols with something like 2 years of minute data per symbol. Is that approximately right?
