Et voila', first Lock Limit Day of my life on Cotton.
Broker: " Cotton is locked at 17% more then yesterday price, you can't sell at more than that price"....
So, my question:Is it always possible to trade on LLD or today is it just a special day?
Thank you

Not a special day, at least not in the last few months.
You cannot trade futures.
Options are open, if I'm not mistaken
You could build a very expensive synthetic long or short futures position in options.... if yours Versailles-style mansion is at risk and still have margin :shock: :( :shock:

If I understand, of course you may sell at the limit up price. Plenty of buyers. Someone who wants to buy will be thankful to you. Buying, forget it. ?Are the back months locked too? Sometimes you can trade the backs. Ive been a spectator in CT for a while now, oh well.

As stated above, you can most definitely sell on lock limit up days, and buy on lock limit down days. But just because something is locked limit does not mean it cannot unlock. Today is a perfect example, where CT was lock limit up, and now has reversed and gone lock limit down!

So just because something gets locked, it does not mean that it cannot unlock sometime before the close if some other news comes out, or a huge order comes in the other direction, etc. Simply requires extra diligence.

Kinti -- you can also use the synthetic to price out what the market is currently thinking the "real" price is for the underlying, outside of the lock. Regardless, I've always wondered how the option marketmakers off-load their risk in such situations, since they cannot trade the underlying in one direction at all? Just blow out the vol to an insane level?

Option traders trade the greeks, i.e. delta,gama,vega, theta and rho.
You can reduce your delta (market direction) also using other options, with different strikes and expiries.
