Recently I have been facing with such a problem, some of the indicators not opening in a separate window but opening in the middle of the chart. I thought that somethings wrong with the certain indicator but not and now I got another indicator what should open in separate window but it shows up in the middle of the chart.
Have been uninstalling MT4 and removing data folder, compiling indicator, have been trying different brokers, nothing seems to work.
I have the same problem, I insert any indicator, it puts me in the main window.
1, please make sure you define #property indicator_separate_window in mql.
2, please make sure you complie the correct file.
I already checked the indicators in MetaEditor and seem to be all right. I have to say that the indicators that come with MT4 are placed either in a window, but not the custom.
You need to create new test indicator by MetaEditor wizard to check if the indicator is correct.
If it is not correct it may be problem metaeditor. If it is correct, just create the new one.
One example of how separate window indicator opens in a main window.
Indicator also added. Code looks fine and I know it is working on others as it should but not on my MT4. I also have tried it on 4 different brokers but they all show the same.
But I just downloaded MT4 from my broker site..And it still shows build 791.
I also was looking at "Journal" tab in terminal is there coming any row with "update" text but nothing comes up.
