I traded in Chicago back then and there were so many mis trades I quit trading Futures …..traded at FOX if I recall correctly ..It was inevitable my execution was the worst of the day ..it seemed they wouldec call me back with execution price for at least an hour and by that time I got the worst execution for that period of time ….Sometimes that happens ..but not every time ..I smelled a RAT ..This was before computers on line..
I pref the Crooks I know on Wall St rather than the ones I dont know in Chicago ….There was no end to the bad execution..I quit Futures
