Hello, You guys seem to have some crazy expectations. Your computer hardware has limits !
Let me calculate, 8 years, 1-minute data ? 480 minutes per trading day, 250 trading days per year = 960K bars per symbol One bar 40 bytes. One symbol 38MB. 100 Symbols = 3.8GB For data alone. =========== Now imagine that if you are running backtest you must have at least TWICE that memory to keep intermediate results. You have simplt run out of memory. Solutions for your "problem": 1. Decrease number of symbols 2. Decrease number of bars 3. Decrease in-memory cache in Tools->Preferences, "Data" to 11 symbols 4. Run 64 bit version of AmiBroker on 64 bit version of Windows and have 10GB RAM installed Best regards, Tomasz Janeczko amibroker.com ----- Original Message ----- From: "mkecera" <[email protected]> To: <[email protected]> Sent: Friday, July 31, 2009 9:55 AM Subject: [amibroker] AB has for Win32 stopped working problem >I tried backtesting on one minute data (8 years,100 symbols, 1 minute data).
