I've been looking at trading eminis for a while now. So today, I figur'd I'll get my feet wet, and try a trade.
Using NAB Online Trading as my broker, I put in a buy order for 3500 ALLKZF eminis 'at market'.
By putting my order 'at market', I thought it would get executed immediately. However, it didn't. After a little while, 200 eminis got executed. A few minutes later, another 99 got exectued...etc until they were all fulfilled at the same price of $2.00
Can someone explain to me why the buy orders were staggered, and not executed at the same time?
What am I missing here?
