That too, wysiwyg;
Many years ago when I was still green and trying my luck with conditional (stop) orders, I found myself a couple of times wondering how my stop was taken out, making me the lowest seller of the day. Invariably, the price would miraculously bounce back up and go ballistic. And then I overheard a broker bragging how he had just run a report over their conditional order book. All he needed was a small sale that triggered the first condition. That led to an automatic avalanche and allowed him to clean up the lot.
