I wanted to ask for people's opinions on this matter? I trade euro bund futures. I place a sell limit at a specified price. the market is already 2 ticks away and i see it is going away even further and it won't come back so i cancel the order. however without me knowing the broker executes the order. I requested the log for the day! the fill of that particular order is not present in the log files of the platform. the logs shows that the order was received, queued, then canceled the platform is strategy runner. the broker claims the cancellation request did not go through quick enough and the order was filled without me even knowing. (on the platform at that time the open p/l doesn't fluctuate and it shows no fill!), and there is no other open orders running at that time. So the order was executed but u don't know because your open p/l is at 0 and is not moving at all(at that time the market was moving in one direction very violently.) i only found out about the fill of the order after i checked my broker statement. 24h later. the broker said because of the electronic trading agreement i signed i am liable for all "technical glitches"! seeing as the log showed no fill i thought i was correct but apparently not! anyone else have a similar experience? btw. this is a major broker that is here on ET.
