Candlestick chart improvements
I've tried so many apps in the last few months that would allow me to easily see quotes for my positions, show all of my portfolio across multiple brokers, and have excellent real-time candlestick chats. Yahoo! does a great job at the first two, but there is some improvement that could be made to candlestick charts (I use primarily on iOS on iPhone and iPad, so suggestions are for the apps). Here's a list of features that I think would make Yahoo! beat out any other competition with good charts (e.g. TradingView, Webull, TOS etc.)
Allow to save chart timeframe. Every time I exit the advanced chart of a stock, and go to the chart for a new stock, the timeframe is re-set. I like seeing charts in 4h timeframe, and have to always select to do this on a new stock every time. I think on the web version however, this is not an issue, so I'm guessing it's fairly easily doable.
For some reason, 1 and 4 h time frame candlestick charts are not updated real-time. All other timeframes I can see candlestick movement tick by tick, but for 1 h and 4 h timeframes, it's just doesn't update. I have to close the chart and come back to it again to see updated candlesticks.
I use dark mode for the apps, and the background color to show extended hours is just horrendously dark. It needs be lightened up significantly.
