## Processing Your Data

Once you have down loaded your historical securities data, you are ready to perform the turtle trading analysis on your data. You have the option to analyze all of your securities data or you may just want to analyze one specific security. To analyze one security, select the 'Single Security' radio button and then select the 'Process Securities' button. When you process a single security, you may also select to plot the theoretical trading results by selecting the 'Plot Results' radio button. This plotting feature is only available when you process a single security.

The plot shows the theoretical trading profit and loss for completed trades. It also shows the security price history with the buy and sell values used by the Profit analysis tool to determine when to start and end a trade.
