Trigger order by exchange that did not execute

Where your order got routed out? If it was routed out down to NYSE, you had to wait for the next round lot transaction the get your odd-lot execution. That would explain 9 seconds delay.

 

so it was a stop gtc. thats different.

2nd para always applies. its more important in less liquid markets and esp options

 

It seems there is a difference of opinion if the issue is illiquid markets or if the issue is NYSE?

 

IMHO it has nothing to do with the liquidity. Every market center has it's own rules when it comes to dealing with odd-lots. It's not the question if the stock is NYSE listed or not, the question is where did you get your fill.

 

OptionTrader, tell us the full details of the order, and you'll get the answer you want. (route, fill price, fill time, next print on the tape, time of next print, exchange listed)
