add posibility to toggle the LIFO/FIFO right on chart without trading DOM

End of last year when I first bought ATAS yearly tariff, there was this LIFO and FIFO toggle at the top of right corner when using the scalping dom.

However somewhere within the period the toggle was removed.

Requesting this feature to be available at the candlestick chart without opening the scalping dom and and make this toggle attach to the hotkeys settings where we can set any hotkey to toggle the LIFO or FIFO mode.
