Thank you for your response.

The error message I get: "Indicator 'macross' caused cTrader application crash. It was removed from all charts. Indicator exception details:

 I installed the "cAlgo.API.Alert" Nuget package and done everything that is written on github Wiki but it doesn't work.

Hello, I need some help with adding this alert popup indicator to my MA crossover indicator. I wanna have telegram notifications. But when apply this to one of my charts, my cTrader crashes and close itself. Could you help me to set it up?
