Hello,
Did you read the manual?
Due to the limitations of TWS (only ONE backfill at a time and
throttling backfill request
for 3 minutes every 40 requests) there is a special method of
backfilling all
symbols implemented that steps through all symbols in RealTime
Quote list one symbol at a time
(to address TWS limitation) that waits until previous symbol
is backfilled prior to starting new one.
Backfill Current option allows to force backfill
of currently selected symbol, while Backfill All RT quote window
symbols allow to force backfill of all symbols listed in Real-Time
Quote window. Backfill of multiple symbols is performed sequentially (one at a
time) due to limitations of TWS.
Best regards,
Tomasz Janeczko
