Inputs

• Inputs, or the data used to construct charts--such as streaming quotes, historical data, averages and indicators--are critical in analyzing charts based on selected criteria. For example, you cannot view a 10-year chart if the provider only offers three years of historical data.
  
  

Types of Charts

• Inputs can be converted into various types of charts, such as line, bar, OHLC (open, high, low, close), candlestick or P&F (point and figure); intraday, daily, weekly or monthly; arithmetic, logarithmic or semi-logarithmic; static or interactive.
  
  

Chart Analysis Tools

• Chart analysis tools (MACD, Bollinger bands, moving averages) can be graphically superimposed on stock charts based on selected parameters or formulae for a more detailed analysis.
  
  

Annotations

• Some charting software allows investors to draw trend lines and make notes on individual stock charts and store them for future reference.
