Entered a short and the stock started hitting upper circuit(or so the CS at RKSV says). I kept getting notifications (Margin at -200%, position will be squared of at 80%) that the position will be squared off automatically, but it didn't execute it seems. I had to manually square it off, following which it did get executed with a huge negative in my balance. Should I seriously consider paying them back? I already lost my existing margin + profits, it seems unfair on their part that risk management systems didn't trigger an order - for me to now pay back the negative? Also can someone let me know what happens in cases like these?
