All of us have suffered such losses due to software failure....such losses are bad enough, the worst feeling is feeling of helplessness and no control on the mounting losses. We save every rupee by tight risk control and such losses hit us very badly.
Thank God that the loss is defined and in this case is not a cripling loss.....I am sure TP will come out of it soon. I have had few such experiences of cripling losses due to software and system failure and in one case when I was a struggling trader, I had to borrow money to pay for the settlement obligation with all my capital wiped off due to a software snag and the broker refused to pay putting his finger on risk disclosure ducument we all sign...very scary thing to happen.
