Modifying trading strategies allows you to modify the currently selected trading strategy. This may be useful if you want to recalculate the backtest results, change the trading strategy parameters (i.e. Size of backtest used to evaluate trading strategy), or the long and short signals.

1. Select a trading strategy displayed on the chart by clicking on the corresponding line, legend text, or Snapshot View text.
2. Once the prediction is selected (highlighted with black boxes), select Modify Selected Trading Strategy from the Edit menu.

1. Select a trading strategy displayed on the chart by right-clicking on the corresponding line or legend text.
2. Select Modify Selected Trading Strategy from the pop-up menu.

1. Modify a trading strategy displayed on the chart by double-clicking on the corresponding line or legend text.

Troubleshooting:

• You must make sure the mouse cursor has changed to a hand before clicking on the line or legend text. If the cursor is still an arrow or a cross hair, the selection will not occur. If you are selecting a line on the chart, it is best to position the cursor over a data point instead of the portion of the line connecting two data points.
• In order to recalculate a backtest you must select the Rebacktest button (from the Trading Strategy Wizard – Results Summary).
