The issue:
On installation of the indicator - with Telegram enabled, I get a flurry of alerts, with or without a cross-over arrow present.
If I change TFs I get a flurry of alerts, if I switch between Renko, Range, regular candles or instances, I get a flurry of alerts.
I'm running (trying) it with my existing cBot - I have never had an issue before, I downloaded your Guardian Angel trial and received Telegram alerts from that just fine.
Using your Message Channel Test I get 1 message:
I don't know what else to do or check at my end...
