(Updated April 16) I placed my bid through WR Hambrecht today.
Last Nov I opened the acct at WR Hambrecht in order to get the IBKR open IPO. But I was not disiplined enough, end up picking up other IPO stocks: HLYS, XFML and GSIT. I already sold XFML before getting GSIT. Now I need to sell more to make fund available to IBKR bidding. Interactive Broker is the leading options trader and market maker in the US. The most famous company did open IPO is Google, followed by MorningStar.
