NYBOT Matching algorythms???

I figured out NYBOT soft commodities matching algoryhtms were based on price/time priority, but I was first on a queue yesterday afternoon and didn't get filled... Is there some exceptions( I was on cocoa ) or is there some hidden orders?

Thanks.
 
It was not far ahead, I just improved the ask at a time the market was slow and saw 10 lots getting filled before my 2 lots.

On ICE website, they claim to use FIFO algorythm "most of the times" or something like that. I don't remember the exact sentence.

It can be a spread order or some hidden liquidity( like on cbot )or an another algorythm used at the time... I don't know I would just like to be aware of it for the next time I trade.
 
Slightly off topic but today I bought Dec Cocoa but I did not realize that I checked Nymex on the IB prompt instead of Nybot.

After I noticed this I got out with a limit order and placed an order to reenter at Nybot a few ticks below and I got it.:)

I did not think there was any trading in the Nymex softs but I guess there is.

The seasonal is positive for Cocoa for the next few weeks.

Did you contact the exchange?

The should give you an explanation
if not a fill.

No, I haven't ever done that for anything. I got my 2 lots filled seconds after the other 10 lots fill and didn't lose anything on it

I just wanted to clarify the limit order priority on NYBOT since I am a new trader on it...

Thanks
