....specifically, short term swing/momentum options trading that may include overnight plays in some circumstances...(as opposed to being only High Frequency Trading)? I am interesting in getting on board with a good prop firn in NYC. I am generally familiar with most of them in the city. But what I am trying to glean here is how much latitude one has in trading at some of them. A more specific question here as to this is....does SMB Capital, WTS Proprietary, Jane Capital, GETCO, and MAKO enable traders to do standard put or call option plays that might be held for hours as opposed to minutes...or days in some instances....and might be inititated prior to a given market close with the intent of holding it overnight?
