When a BO SL BUY order is COMPLETEd, the txn record's parent_order_id is NULL
We checked multiple fresh Bo-SL Buy/Sell orders, we got parent_id for all orders.
Hi @rakeshr
No, not postback.
Here are example trades - https://quantindia.in/misc_afjhauweroiuafdlkjqew/trades_24Sep18.txt
You can see that there are several NULL values for parent_order_id column. This table stores whatever is returned by the API.
If it is a first leg order then it is possible that it will have NULL value.
