Bollingerband

Is it possible to display the (real-time) Bollinger Band width at the top, where information such as the lowest price, 24-hour volume, etc. is displayed? If you're making your first purchase, you first need to measure the width, and once this width is displayed at the top, it's displayed again. It's just a question, and I don't know if this is possible. Thank you very much for your reply! I'm attaching a photo of the recently released CryptoCoiners CC Trader.
