Thread: How to make indior output 0 as the value instead of blank

I discovered the connected indior. I need to modify it so that the sparks are instead of nothing (as seen in attached screenshot).

How can I change it so it outputs a 0 when no PinBar is noticed, and then when one is discovered, it will place an arrow and output will have a value? Thank you for your help.

Xaphod,
Thank you for your answer.

I included SetIndexEmptyValue(0,0.0); for each one of the buffers, however as could see in the pic, it still does not have an empty value of 0, just blank. What did I do wrong?

The guide states:
Empty values are not attracted or shown in the DataWindow.

So that you'll have to eliminate SetIndexEmptyValue or set it to (EMPTY_VALUE) and explicitly set each index value to 0.
Search for buyPB and set it to 0 in the start of the while loop.
While (posgt;0)
buyPB[pos]=0;
...
...
etc

So that you will need to remove SetIndexEmptyValue or set it to (EMPTY_VALUE) and explicitly set each index value to 0.
Search for buyPB and set it to 0 at the beginning of the while loop.
While (posgt;0)
buyPB[pos]=0;

I thought that SetIndexEmptyVlaue (1,0.0) would set the value at 0.0 when it was empty. Okay, my mistake. I did as you said it works now. Thank you very much foryour help and teaching me this.

It is possible to use the function http://docs.mql4.com/customind/SetIndexEmptyValue in the init() function to achieve that.

So did I. However, the manual stated differently. Glad you got it working as you want.
