[amibroker] How to limit to top 5 in an Exploration

["gelsner99" <gelsner@xxxxxxxxxxxxxxxxx>]

For the simple AFL code below, what would I need to change so that when I run the Exploration it lists only the top 5?  


Fund                            = Close;

Period                           = Param( ".....Period", 126, 63, 252, 63);

// Calculate Total Gain and Annual Gain
TotalGain                        = ROC(fund, period);
AnnGain                          = Nz(100 *LastValue(((TotalGain/100+1)^(252/period)) - 1));

// Exploration
Filter 		= 1;

AddTextColumn(FullName(),"Fund Name",1.0);
AddColumn( AnnGain,       "AnnGain",   1.2 );

SetSortColumns(-4,);
