Multi-Time Frame Indicator Reference

[ECI-Ed]

The attached indicator is attempting to use EMA's from a 3 minute time frame to filter a simple alert on one minute volume, but when I try to compile it I get a "Cannot apply indexing with[] to an expression of type 'double'"
How do I get around this?
TIA

Hello ECI-Ed,

Thank you for your post.

As you have already declared the BarsArray for the EMAs there is no need to call them as [1][0], just [0]:

                 if (Avg < vBMinL && _emaf[0]>=_emas[0]) {
                 	    vol1col = Color.Yellow;
                 	    if (lAvg > vBMinL) {
                          PlaySound("Alert_Low_Vol.wav");
                      }
                  }
                 if (Avg < vBMinS&& _emaf[0]<_emas[0]) {
                 	    vol1col = Color.Yellow;
                 	    if (lAvg > vBMinS) {
                          PlaySound("Alert_Low_Vol.wav");
                      }
                  }

For the Font you need to set this in the Intialize() method as the following:

Font textFont = new Font("Arial", 14);

Attached is the indicator with the corrections.

Thank you Patrick,

That solved the compilation problem, but a new problem has appeared. The subpanel is now displaying 3 minute volume every third bar. I thought I could fix this by adding [0] after each time I called the Volume, but that hasn't fixed it. What am I missing?

Hello ECI-Ed,

Thank you for your response.

I am not seeing the same item on my end. Can you provide a screenshot of this on your chart?

[ECI-Ed]

Sure. Attached is a screen shot of my 1 minute chart.

Hello ECI-Ed,

Thank you for your patience.

Change the Vol.Set(Volume[0]); to Vol.Set(Volumes[0][0]);.
