Hi,

As I'm checking, the issue seems to be Zorro 2.53.6, but when I switch back to Zorro 2.48.1, the problem is solved.

It seems that Zorro (2.53.6) is unable to load bars timely from OANDA's API.
For instance, the run() function is supposed to run at Hour 2:00, but runs at random timings 2:53, for some reason.

Will update more as I experiment further into this.
