MULTICHARTS 8.0 BETA 1– WHAT’S NEW
Published on February 13, 2012 in Beta.
MultiCharts 8.0 Beta 1 is big step forward for our traders. It’s the first time that EasyLanguage scripts can be used on 64-bit software, which means only your physical memory is the limit for backtesting, charting, optimization or trading. Several smaller features were added, and bugs affecting stability and data handling were addressed.
64-bit means that all modules in MultiCharts were rewritten to be 64-bit, so they can use all available RAM on a computer. Performance of the application is now limited only by the amount of physical memory in your computer. Limitation on number of bars on charts, mapping and importing ASCII files more than 4GB, number of symbols and plots in Scanner, and displaying strategy performance report with large number of trades were all lifted in the 64-bit version.
