Quote from AAA30:
Ok you need to go with a direct access broker. So there is no delay in orderplacement and execution. Paying .005 a share or 7.95 a trade should not matter at all. If you use IB you will also get access to algos that you can use to execute your trades and the abillity to use other order types to hide your orders or only show a small quantity of it. You will get slippage, some times substantial, on OIH on a 10K share market order and the only way to minimize this would be with tape reading skills to pick your spots. Again commisions will not mater execution is more important.
I wouldn't care about "hiding" anything... I'd expect to be nailed for a few cents on the fill. Just better a few cents than a "lotta" cents.
