What does tradeSize represent during Opening and Post-Trading session for Vietnam Rics ?

For Vietnam stocks, we are receiving incorrect/garbage trade quantities during Opening and Post-trading sessions.

For example,

For ric=DIG.HM , date=20220510 and RFA version=8.2.0

We have received a constant tradeSize=50400 (FID 178) for all trade messages before 09:15am during opening session. During normal market hours, the tradeSize starts changing and looks reasonable.


Is there a special meaning to tradeSize during Opening and Post-Trading sessions for Vietnam?

    First of all, you need to check the code if it calls the isBlank method before accessing the data.

    For example:

    void Decoder::decodeData(const Data& data)
    {
        if(!data.isBlank())
        {

    Getting a value from the blank entry can get an unexpected value.

    Otherwise, you need to contact the content team directly via MyRefinitiv to verify the value of the tradeSize (FID 178) field during Opening and Post-Trading sessions for Vietnam stocks.

  • We saw an example where tradeSize was blank and tradePrice was not blank.
    What should be the interpretation in this case?
    Should we set tradeSize to zero or use the tradeSize from previous update?


    Thanks.
