Why Indicator line does not seen in expert correctly ?

[fx-analysis]

Hello,

I have a quite strange problem. I have indicator, which plots one line with constant slope per bar.

If I include this indicator into expert indicator line plots strange way during testing period. Before testing period it looks ok. If I reexecute indicator on expert it plots OK.

What is solution ?

Thanks,

Edas

Before testing period Indicator plots Trendlines (sloping lines).

During testing period it plots horizontal lines, not trendlines.

Whats the matter ? I think it should be possible by expert to read different icustom buffers, not only equal values.

Add this and see what is output when the lines are being drawn horizontally . . .

UpTrendBuffer[i]  = HighestHigh + (HighestBAR-i)*1*Point; 

//  add this line

Print("i= ", i, " HighestHigh= ", HighestHigh, " HighestBAR= ", HighestBAR);
