[R-SIG-Finance] function 'addtxn' in blotter package can't add intraday trade into account?

[domodo]

Ulrich,thanks for your reply.

I found the reason why equity are always zero. the argument 'initDate' in
initPortf and initAcct should be earlier than market data's start date,in
this case, the start date is '2012-01-18 09:15:00',so argument 'initDate' in
initPortf and initAcct should at least be '2012-01-18 09:14:00' or earlier. 
Having replace both of the value of initDate with  '2012-01-18 09:14:00', I
got the result of txns as below:

> head(txns)
                    Txn.Qty Txn.Price Txn.Fees Txn.Value Txn.Avg.Cost
Net.Txn.Realized.PL

-309.816

all transactions are OK,except the first transaction. why it occurs ? I
tried to run the codes in debug mode line-by-line,but couldn't find the
reason.

PS:
I couldn't find the reason why argument 'initDate' in initPortf and 
initAcct must be earlier than market data's start date/time in help
documents.

regards.
