New AFL functions Say() - text-to-speech conversion FFT() SetChartBkGradientFill() SetSortColumns() GetPerformanceCounter() RequestTimedRefresh() and few others...

AFL: Say() added Text-To-Speech capability via Say

() AFL function. Now AmiBroker can speak out loud any text.if( LastValue( Buy ) )

Say(”Buy signal on “ + Name() + “ at “ + Close );

This is controllable from formula level so you can make it to speak depending on market conditions, signals generated from your formula, etc.

AFL: SetChartBkGradientFill () SetChartBkGradientFill( topcolor,

bottomcolor, titlebkcolor = default ) Enables background gradient color fill in

indicators. Please note that this is independent from

chart background color (background color fills entire pane, gradient fill is only for actual chart interior, so axes area is not affected by gradient fill)

AFL: FFT()FFT( array, len = 0 )

Performs FFT (Fast Fourier Transform) on last 'len' bars of the array, if len is set to zero, then FFT is performed on entire array. len parameter must be even.

AFL: SetSortColumns

SetSortColumns( col1, col2, .... ) Automatically sort exploration result list. col1, col2, ... col10 -Column numbers are ONE-based. Positive number means sort ASCENDING, negative number means sort DESCENDING.

AFL: SetSortColumns examples

// sort by 5th column in ascending order SetSortColumns( 5 )

// sort by 3rd column in descending order SetSortColumns( -3 )

// sort by 1st column (asc) AND // then by 2nd column (desc)

SetSortColumns( 1, -2 );

AFL: GetPerformanceCounter()

allows high-resolution performance timing

GetPerformanceCounter(True); for( i = 0; i < 1000; i++ ) { k = sin( i ); }

elapsed = GetPerformanceCounter(); "Time [ms] = "+elapsed;

Other improvements HoldMinDays / EarlyExitDays feature 'Every tick' chart refresh capability
