Slope Directional Line Indicator in an EA

New comment
 

Hi

I am trying to use the Slope Directional Line Indicator in an EA. It works great, but when it is in Bullish trend it returns the actual value of the indicator which is great, but when it is in a bear trend it returns the EMPTY_VALUE, which show the trend, but I need the value also in a bear trend. How can I get the Slope Directional Indicator to return the values on Bull and Bear trends for me, and not just the EMPTY_VALUE in bear trend. Would help me a lot on my EA.

I use the plain indicator I downloaded on Google.

Thanks

    Are you expecting everyone to try to find which indicator is the indicator your using. There are no mind-readers here. If you had attached it maybe someone might be able to help.
  2. Is the indicator multi-colored? Then there are multiple buffers (one per color) Use the OTHER one.

In the navigator screen it is only yellow. Or must I look somewhere else.

It returns the correct value if bullish, but return the EMPTY_VALUE when bearish. So it works perfect, to know if trend is up or down, but I would like to get the bear value returned the same as it returns Bull value.

Here is the indicator code. Works 100%, but return only EMPTY_VALUE on down trend but the real value of the bull trend. But it works 100% to get the trend.

Hi

Thanks - Got it. Sorry first time I am using iCustom. Your comment about more than 1 buffer made me realize. I have never programmed an Indicator, only EA's, and Always with standard Indicators.

Thanks, Sorted!!!
