This is so basic and every platform has it. I usually trade on the 5min chart on ES but I always check higher timeframes like 15min, 1hr, 4h, daily which I have open in separate chart tabs for quick browsing.
I want to be able to draw a level, box, fibonacci, etc on any of them, and as long as it is the same instrument, have it show on all the other charts I have open at timeframes as well. In tradingview this is done with a simple “drawing synchronize” option. On Sierra you can even customize which timeframes specifically copy which other chart.
This is very basic and should be implemented asap.
