Cannot get output buffers from custom indicator to respond

[jcalow]

Hi,

I am using the attached custom indicator. I am simply trying to get an arrow shown on the chart when the 0 output buffer from this indicator is equal to more than a 0 numeric value. I have managed to get it to run in strategy tester and it picks up all the correct input parameters and shows the indicator. But I can never get it to output an arrow. I have also tried to get it to output an alert message instead, but also no luck. Please tell me what I am doing wrong. Many thanks.

@jcalow sorry, i can't attach it on the chart
I suggest to search on google, there are a lot of similar indicators, also with source code

Ex4 files are difficult to upload to fxDreema. Don't you have the mq4 version?
