The tradingview bitcoin chart allows you to keep all your settings - it keeps all your lines that you draw on every chart , (with accuracy - on every time frame)and applies the same indicators to every chart .It is free , but I pay about $29 USD a month at the moment to use it -so that I can get more features. They also give you a half price rate if you pay for a year upfront - not doing that just yet . Just google BTC USD price - and the tradingview link comes up. You would find most charts there.
