I see this:

I use 1w for the interval. Maybe there is an issue or problem that bitcoinwisdom got, and they still fix and solve the problem. You can use tradingview for making analysis and try to visit bitcoinwisdom in a few hours later, and I hope that the problem will be solved.
You see that because you are using a weekly candle chart so it's not still reflected. After a couple of months you will see it's also a flat line on the weekly chart. It's dead, I recommend that you start using bitcoinwisdom.io as im doing (thanks to these that mentioned it.)
I was aware of cryptowat.ch and I was considering replacing bitcoinwisdom with that, but I find that website too bloaty on my browser. Tradingview is a mess to take a quick look in my book, that's for hardcore technical analysis and not to get a quick glance at the price. bitcoinwisdom is a nice sweet spot of simplicity and enough info with everything I need. Probably im overrating it due nostalgia factor as everything that involves nolstagia tho.
