Can't load template with custom indicator into the strategy tester

[Klaus Schwarzkopf]

Hello,

i saved a template with my custom indicator KeltnerChannel in Metatrader 5 and can load it there. But when i try it on the Strategy tester, it isn't working. 

CS 2 14:01:26.612 Custom Indicator loading of KeltnerChannel WS30,M1 failed [557]

It's only working, if i use a build in one.

How can i fix this?

Best Regards,

Klaus
