Matlab by The MathWorks lets you access, visualize, and analyze historic time-series data to identify patterns or uncover complex relationships. From within a single environment you can:

• Access data from multiple sources including files, spreadsheets, databases, data providers, and the Web
• Store data in financial time-series objects to simplify data management, data transformation, missing-data handling, and date-math calculations
• Perform technical analysis with moving averages, oscillators, stochastics, and indices
• Create custom analysis routines and visualizations or animations to capture, present, and share your analysis processes and discoveries
• Customize your analysis environment with advanced functionality from signal processing, statistics, or econometrics
