No but and sell wall?

Just wondering why does this have no but and sell wall like they do in crypto? So you can see the bugs and sells also can you update the app so I can see all stocks with prices so I can see cheap ones and expensive ones can’t do that on mobile app

I’d say it’s not high up on the priorities list to add a sell wall. Using oscillators such as MACD and RSI you can get a good view of what’s happening
