Chart viewing problem

 

Hi guys here, i was using MT4 before.  In MT4, i can hold and drag the chart freely up and down far beyond the highest / lowest price shown in my window (attachment: beyond highest sample).  But i can not do this action in MT5, since it will auto "lock" the chart between the highest and lowest price that shown in my window (see attachment: locked chart).

Hence, i want to question about how to:

drag the chart up and down without any limitation; meanwhile,

the vertical scale can always be fixed in 1 dollar per grid.

Could someone help me? Thanks a lot.
