What type of Volume? Tick or Depth. What do you think it should be. Why?
 

Time displayed on chart is broker's server time.

H4 bars and higher will be different on different brokers because of when they start. (H1 bars for India will differ because of fractional time zones. Are there India brokers?)

Brokers using UTC (e.g. IBFX) have a 2 hour H4 and D1 bar on Sunday, while those using UTC+2 (e.g. Go Markets) don't have any Sunday bars.

These differences are in addition to the difference price feeds of each broker.
