Issue to plot value from my array in my indicator

[Vincent V.]

Hi, 

I have create a new indicator, it is my first one and I have an issue to display the value in my chart.

The value is stock in my array  Buffer_yhat1 and the value comes from my function ->  nadaraya(close, ArraySize(close), h)

Can you help me ?

Here is the code :

Check your data window, if the values are showing.

Yes it shows but it looks like it calculate only from the bars when I open MT5.

How about setting what you want to display

#property indicator_type1   DRAW_LINE
