Hi

Need help from support or anybody who can help me. Since the last update I don't see my indicator anymore: "HeikenAshiSW" (in the JForex 1M Chart). I need this indicator. Why doesn't it show anymore or work anymore?

Thanks for any help on this matter.

Best regards

Just thoughts out of the blue...
- Have you recompiled since the update? (maybe there was a change regarding compiled indicators...)
- Are you able to recompile at all?
- If yes, are you able to load it as Custom Indicator to another chart with different timeperiod?

Hi

Many thanks for your thoughts. I tried to recompile but it didn´t work. It also didn´t work with other timeperiods. In the meantime I found another indicator (Heikin-Ashi) and it worked.

See attached.
