MultiCharts

MultiCharts is a professional trading platform that supports both discretionary and automated trading, with powerful strategy backtesting and optimization tools. The platform is compatible with TradeStation's EasyLanguage, making it easy for traders to migrate their custom studies and strategies. MultiCharts excels at portfolio-level backtesting, allowing traders to test strategies across multiple symbols simultaneously with realistic slippage and commission modeling. The Strategy Optimization engine uses genetic algorithms to find optimal parameter combinations without testing every possible permutation. The platform connects to dozens of brokers and data feeds, giving traders flexibility in choosing their execution and data providers. MultiCharts uses a one-time licensing model ($1,497 for the standard edition) rather than monthly subscriptions, which makes it cost-effective for long-term users. A free edition with limited features is also available.
