Getting Errors

Hi all

Any reason why i am getting these errors at time. My broker is Oanda


!Trade not open - 8980
!Result: {"lastTransactionID":"9054","errorMessage":"The trade ID specified does not exist","errorCode":"NO_SUCH_TRADE"}
!9054
!The trade ID specified does not exist
!The trade ID specified does not exist
!Trade not open - 8980
!Result: {"lastTransactionID":"9054","errorMessage":"The trade ID specified does not exist","errorCode":"NO_SUCH_TRADE"}
!9054
!The trade ID specified does not exist
!The trade ID specified does not exist
!Trade not open - 8980
!Result: {"lastTransactionID":"9054","errorMessage":"The trade ID specified does not exist","errorCode":"NO_SUCH_TRADE"}

Trade closed by stop loss, or closed manually. You see more in the rest of the log.

So,

my question is a wrong. I want to call BarPeriod=6, but with offset 1,

first bar start not "0" but "1" minute

standard is 0-5-10...55 but i want 1-6-11...56

Is a possible?
