Just a note. Trading ETF's on ISLD is fast, however you will give up price improvement-for speed. There is no price improvement on ECN's. Many times you will get price improvement on QQQ,s & SPY's on AMEX & NYSE. I know many do not like the "slower" speed & many think the specialist is "cuffing" orders, but you will get noticeable price improvement many times. I think it's best to
trade all routes on ETF's AMEX,ISLD,NYSE & NYSE NX and use the
route depending on the situation. If the market in SPY is Bid 109.74 Ask109.76 and you want to buy with equal size and it is not a fast market, If you want to Buy at 109.75 and prints
are going off on the AMEX at 109.74, it might make sense to send
your order to the AMEX to Buy 500 SPY@109.75 and get potential
price improvement at 109.74. This would be especially true if
the best offer on ISLD or NYSE is 109.76. Could you miss the stock
at 109.75? The answer is "yes", but for the pontential price
improvement, I would send the order to the AMEX . Most traders
who use direct access software and trade ETF's on ECN's are giving up price improvement mant times to gain speed of execution. I welcome any comments from traders.
