why is there no more "IOC" order type on TWS?

a few days ago i saw a post saying NYSE dropped "IOC" order type. I checked IB, indeed no IOC order anymore, even for nasdaq and amex symbols.

 

I think you or the post are mistaken.
IOC orders must be executable orders when entered or they will be rejected.

 

IOC order not supported anymore

 

Have you looked at the API? Maybe you can still send it through API

 

No comment about this IOC order.

But I have seen
some brokerage firm which had things like
bracket order , stop order for a particular financial product.
Then later, they removed the bracket order, stop order due to whatever reasons !
Till today, I can't use bracket order, stop order from that brokerage firm for a particular product.

 

either works
