Why crude oil (mcx) price fluctuates all of a sudden

One reason I know why it fluctuates drastically on Wednessday is coz it’s Inventory Report gets released , but I’ve seen on some other days also it fluctuates suddenly. Many times I searched for any recent big news also on google related to that but I didn’t find anything.

Can anyone help me with that? why does it fluctuates just suddenly even when I don’t see any news neither any internation market opens at that time.
