Mike,
This corrected version produces the exact structure...thanks for the Null tip...
resline = Null;
for( i = 2; i < BarCount; i++ )
{
prev = resline[ i - 1];
resline[ i ] = IIf( H[i-2] < H[i-1] AND H[i-1] > H[i], H[i-1], prev );
}
Plot(ResLine,"ResLine",colorRed, styleLine|styleThick);

Nope.
See my earlier post
http://finance.groups.yahoo.com/group/amibroker/message/143523
Your solution will plot zero for the first 2 bars when it should be NULL.
If the original poster wanted to keep your structure (i.e. IIF and no
pre-assignament of OneHigh, TwoHigh, ThreeHigh), then just change the
initialization of ResLine to ResLine = NULL.

at line 7? could you please make the correction to the looping sample and
re-post? I'd really appreciate it.
