Hi, Chris. I am contacting NinjaTrader support with this question.
This product is not advertised to send alerts when a position opens or closes; it is a shared service and will only send alerts that NinjaTrader allows. ChatGBT seems to think it sends trade alerts, but it may not. I will check myself.
I would say you cannot send an alert when a trade opens, so double-check with NT. You will need another tool to do this. I have added a note to build one.
