What can trader do with the spike for CAC40 that happened today morning? Is this legal? Volatility picked-up, bla bla bla, obviosuly their system adjusted and I was closed 4110 and 4214 (corected to 4114, ) ?! Luckily, I was up but If I weren't I would be quite dumped.
Outside of a safety stop resting in the exchange limit order book or having an options hedge not much you can do. Crazy spike considering the initial volume was only 200, looks like Someone forgot to iceberg.
Yeah, I have to read more about the order books and algorithms, especialy the ones that can be used to screw me.
