how does ZigZag code work?

[Deleted]  

Hallo everybody,

trying to understand how the standard ZigZag code works. Can anybody provide a commented version?

What I particularly don't understand is the following:


IndicatorBuffers(3);
//---- drawing settings
SetIndexStyle(0,DRAW_SECTION);
//---- indicator buffers mapping
SetIndexBuffer(0,ZigzagBuffer);
SetIndexBuffer(1,HighMapBuffer);
SetIndexBuffer(2,LowMapBuffer);
SetIndexEmptyValue(0,0.0);


What does "SetIndexEmptyValue" result in? And how do the three Buffers work? For every bar there ist either a 1 in HighMapBuffer or in LowMapBuffer?

If somebody could clarify a little bit the way the code works I would be very grateful.


Thanks in advance,
