Well hate to break it to u but there were studies dont on market transaction and your uptick rule is incorrect..
we used to just put in a buy order for one share, yes one lousy share and that would cause the uptick, then we would sell short and it was demonstarted to the sec in a open meeting of how it was done...so for one lousy share through direct brokers which would cost u one penny for the commission it could be accomplished and all hedge firms wer doing it..
so the bottom line was it did nothing!!!
this is actually a real market now as short sellers vs, buyers is true now minus the naked shorting..
take away the naked shorting and u would have a true markert...buyers vs. Sellers...thats a true market...
