sir i have posted all the screenshots now. I wrote them on same day and called them on same day. They didn't assign a person nor called me giving any satisfactory answer
I think you have not posted all the screenshots.
Open your contract note and do the following:
1) Count the total Buy quantity traded initially and keep note of trade time.
*Now once the buy is executed, you have open target order and sl order
2) Have a look at the time stamp and see which order is executed next ( target order or sl order ) and what quantity.
I see from the execution time that sl order was triggered first, not the target order ( but only partial quantity ).
So if the sl order was partly executed, may be the target order quantity was not automatically reduced to the extent of sold shares and
when price went up, the full quantity in target order was traded. If this is the case, the initial quantity traded when sl was triggered remains as a short position and it was only squared off during closing ( as per your screenshot ) incurring this huge loss.
But even if we have to consider the above case, sell quantities traded at (9:53:06 hrs ) and buy qty traded at (15:24:33) should match, which is not the case as per screenshot you have given. Your full contract note may give clear picture.
First sort out the reasons for difference in orders/qty's placed and actual trades. ( If they are technical problems or is it due to drawback in their bracket order feature ) and be sure if you really did not place any new orders/edit open orders and then escalate the issue strongly.
But anyways try to sort out somehow and get the debit cleared from your ledger. Because this debit may impact your CIBIL score.
