Hi, thank you for reporting this, so far we have thousands of customers using our indicators and there have been no reports of any issues, it works for us on IC Markets 4.2.22 as shown below, if none of our indicators is working then I would say that you have an issue with your PC or cTrader installation.
maybe you have an issue with your settings, if you provide your broker name and version of cTrader together with the same screenshot as I have shown above we can investigate further.
