Maybe your application/code doesn't support more than one instance per machine. Was this case part of your initial requirement? If it wasn't, then it's not the developer's fault (or maybe he should have been bright enough to think to ask you that question!). And I'll repeat myself, no code is 100% bug free. Shit happened and shit will happen again. You just need to have a good workaround plan when it happens.
IIRC, his errant positive trade made more than his errant negative trade, so in cash would be ahead. Is that right Hil?
Yes, net 6k outlier (9k positive outliers on 9/11, 8/29, 3k in negative outliers on 11/13). I did not include that in the chart, but it does reflect it in the broker statement + normal profits.
If you have questions about pnl history, you can just literally click the quoted post all the way to the beginning. I did that intentional so that people can check what happened for every erraneous event. Obviously nobody really bothers to read .
