A button to sync two or more timeframes of a currency for better backtesting. I want to see the 4hr and the 1hr in on multichart window, so when i click "next candle" on 4 hr it gives me 1 candle in 4hr and 4 candles in 1 hr

and when i click "next candle" on 1hr, the next candle on 4 hr appears after clicking 4 times on the 1hr...
