I have heard complaints from some traders at one prop firm that they couldnt hit bids with long positions....because the firm was Net short, the sale of the long would create an illegal short sale so it had to be done on an up tick......NOW THAT SUCKS!
I dont know what the solution for the ex-bullet traders is...learn more NASDAQ stocks? "Traditional" shorting of listed equities takes ALOT of skill, and you always suffer pain first.....the ES/NQ are different animals, I can't quantify this...but since bullets were eliminated, they seem "crowded" with shorts, holding them up longer, untill they slowly give up.....anyone else noticing this?
As a historical anectdote...Livermore said the augment of the uptick rule is what did him in......he couldn't adjust.
