Tool/App for technical alerts

My searches end up with having to give up cc info only to find out the platform or free trial doesn’t do what I need. I am willing to pay for it but the hunt has become exhausting.

Looking for real-time alerts on wide variety of coins for EMAs, BBand crosses, RSI, VWAP primarily.

Mandatory: Realtime and wide variety of coins (not a stock broker that added major coins only).

Thanks for any input.
