take a look at bardist, see:

as i remember, @vladisld did experience this issue, too. maybe he has some insights into this? sorry, if i am wrong about this @vladisld

i experience the same issue using oanda in live mode, but i did not have the possibility to create a reporducable example and did not investigate that issue much. I collect some info about this issue here: https://github.com/backtrader2/backtrader/issues/32

Maybe you have some code which reproduces this issue?

This does not help you, i suppose.

I added a workaround in backtrader which may help you.

I changed the block to the following code, which works for me, but is a ugly solution:

                # Get index to minimum datetime
                if onlyresample or noresample:
                    dt0 = min((d for d in dts if d is not None))
                else:
                    #dt0 = min((d for i, d in enumerate(dts)
                    #           if d is not None and i not in rsonly))
                    dtstmp = {d for i, d in enumerate(dts)
                              if d is not None and i not in rsonly}
                    if len(dtstmp) == 0:
                        dtstmp = {d for i, d in enumerate(dts)
                                  if d is not None}
                    dt0 = min(dtstmp)

Glad that the issue resolved.

This issue was not yet posted, so I cannot tell if this happens often.

@T-H said in Order Synchronization:

But then I realized that there is no id of transactions from 1845 to 1847.

also for this, i am not sure why this happens. in btoandav20 the missing transactions should be fetched after a reconnection happened.

for msg_type, msg in response.parts():
                    # if a reconnection occurred
                    if reconnections > 0:
                        if last_id:
                            # get all transactions between the last seen and first from
                            # reconnected stream
                            old_transactions = self.get_transactions_since(
                                last_id)
                            for t in old_transactions:
                                if msg_type == "transaction.Transaction":
                                    if t.id > last_id:
                                        self._transaction(t.dict())
                                        last_id = t.id
                        reconnections = 0
                    if msg_type == "transaction.Transaction":
                        if not last_id or msg.id > last_id:
                            self._transaction(msg.dict())
                            last_id = msg.id

its this code block in the store.

i would need some code which reproduces this behaviour, else it is just guessing about the issue.

@T-H i don't understand what you mean with:

Is there an ID that identifies a set of brackets instead of a tradeid?

the BatchID is the id of the order that created the transaction. But this is an oanda thing. I don't use the BatchID in btonadav20.

I have added a issuee on github for this.

https://github.com/happydasch/btoandav20/issues/59

to explain it more, btoandav20 will not recognize the child order, since they are assigned to the canceled order. the new order will not trigger the child orders.
