So you are only talking about a normal weekly chart with a developing last bar?

I am disappointed. Most charting packages can do that.

What charting packages are you using?
I use TOS and Amibroker, but they don't allow me to view the weekly chart the way Stockcharts does.

The chart was produced with NinjaTrader, just select the proper end date.

I have AmiBroker too. You can do that there also for sure. If you wanna change just the last value of weely bar on daily interval then use barreplay. As mentioned almost every software can do that.

Thank you so much for the info.
I have never thought of using "Bar Replay" in AmiBroker this way

Does anyone know if I can also do that in TOS??
I like to use TOS's charts but I haven't figured out how to view the weekly chart on daily basis.
