iz zigzag pointing up or down?

New comment
 

HI all!

I am relatively new, and know relatively little.


Can somebody explain to me what I should do to be able to access the latest top or bottom that the ZigZag indicator plots out?

I don't need them all, just the latest one...

I use this line to access the zigzag, but I don't even know what the last two 0's stand for (what are they?) and when I try to print the value of zig, it only givees me 0.0

double zig = iCustom (NULL,0,"ZigZag", 12,5,3,0,0);

The last is not necessarily bar zero. You need to find it.

The last two zeros are the value of the index buffer, and bar.

You can loop through each bar and get the buffer index values 0-9 and that gives you the values.

So, the following gives the value of bufferindex 0 at bar 10. 

double zig = iCustom (NULL,0,"ZigZag", 12,5,3,0,10);
