Lock chart position

Hello. I would like a feature where if you switch from one timeframe to another, the chart will stay anchored and/or i can go back to that time. For example, if i marked something on a 15m timeframe two days ago at (time), when I switch timeframe to say 1m or seconds chart, i can go back to that point of time that i marked. I find it difficult to back test currently in this platform because every time i do this, the chart manually goes back to the beginning with no options.

• Also, another feature I would like added is where you are able to go back to the trade you took via on your trade history. Also related to backtesting purpose where you click on that trade and it takes you back to that point of time.

Thank you.
