Lets compare that trade with IB. With IB that trade will cost you $502.5. Also they dont give you liquidity rebates either. With pointdirex, that same trade will cost you 507.95. So you are not looking much of a trade price difference. Plus with pointdirex software you get many added features that IB does not provide for equites trading. So its a traders preference what they choose. Also if you are a trader who does good amount of volume, they do provide liquidty rebates. So lets say they give you a rebate of $2 dollars on that trade. So you would actually make $192.5. I do trade with pointdirex.

To the sarcastic poster who accused me of "selling something": I have nothing for sale except millions of shares of small stocks. I appreciate the legitimate comments. What about short inventory in under $5 stocks? thanks!
