Hi,
I checked into archives about this error. It's very stressful to live
with that.
My database is three future contracts in 1 minute bar in real time,
and one index in one minute.
I ran a backtest on the running contract ( in RT) and I displayed the
older contract ( last month) to run the backtester.
No problem till that point.
The issue came after I came back to the contract of this month, and
the backfilling hanged and send the wellknown error message :
Plugin status
Connected OK
Last message from TWS:
FCK8-MONEP-FUT, 322, error processing request: "qb'; cause- duplicate
ticker ID for API historical data query
I manually reconnected and datas disappeard from may 18 th.
Unfortunately I pressed Yes to save database (as I activated "ask to
save changed data" feature ), bad idea.
And after many attempt of bakfill I lost datas from 19 to 30 of may.
I closed AB, and reinstalled the backup up database.
The backfill worked by itself. All the datas were OK.
The damned error message was still there.
I manually Reconnect ... and I lost again datas from May 18 to today.
I Unchecked Request data on save (RT only) and I lost the datas, too.
Right now :
unchecked "ask to save changed data" feature
checked Request data on save (RT only)
no manually Reconnect
I check if my datas are Ok and menu | Save database
IB throttling message alternates with Error message 322
If I check tools | preference | limit number of saved quotations max
1000, I lose datas, before May 2
I verified the path for the database and my datas went deeper into the
directory.
Through Explorer, I manually moved them back and I did not went back
into DataBase setting.
If I save the database while the 322 error message is blinking, I lose
my datas.
I am not convinced that the issue is only IB side. AB should not kill
my datas, or at least, should not kill more than one day.
NB : this morning the Future Rollover IB feature asked to add the June
contract. I said yes and keeped other.
Hope this help.
Regards
