hi every one
i have a problem when i try to merge orders in strategy code
i get a reject to merge and the message tell me that the group not found
i try to use mergedOrder.waitForUpdate(5, TimeUnit.SECONDS);
but it keep to give me a reject after few merges that did happen

if some can help me with that i will be very happy

It might be that some of the positions that you are trying to merge are already being closed by another request and therefore you get this message.

i dont think that the postions is close this is the function that i write

private void mergeFilledDeals() throws JFException
{
m_orderLabel = m_labelDateFormat.format(new Date());
String firstFilledLabel = "MERGED"+ m_orderLabel;
IOrder FilledOrder = null;
boolean isfound = false;
List<IOrder> FilledOrders = new ArrayList<IOrder>();
for(IOrder o: m_engine.getOrders(c_INSTRUMENT)){

if(o.getState() == IOrder.State.FILLED)
{

//FilledOrder = o;
FilledOrders.add(o);
isfound = true;

}
}


if(isfound == true && FilledOrders.size() > 50)//&& FilledOrder != null)
{
if(m_isMergeSucceful == true)
{
m_mergedOrder = m_engine.mergeOrders(firstFilledLabel, FilledOrders);
myMsg(m_msgLog,"INFO","merge order have been send");
}
}
if(m_mergedOrder != null)
{
for(int i = 0 ; i < 10 ; i++)
{
IMessage message = m_mergedOrder.waitForUpdate(5, TimeUnit.SECONDS);

if(message != null)
{
if(message.getType() == IMessage.Type.ORDERS_MERGE_OK)
{
m_isMergeSucceful = true;
myMsg(m_msgLog,"INFO","merge order have been aproved massege from api " + message);
break;
}
}
else
{
m_isMergeSucceful = false;
}
}

}
}
what am i doing worng ???
it do only one time merge and in the second time it just say merge in progress ..... and never return a merge is ok

Please extract from that a full example strategy which would replicate the behaviour that you are describing. For more on merge and some examples see:
