Detail: My primary interest is in getting extremely tight limits timely executed, by a market maker which has a very high volume of Dell going through it. This is a problem, because Schwab's MASH has done an especially good job, on anything above 10,000 shares. The highest I have tried has been 32,000 shares. I set my limits so that I sell higher than the ask, and buy lower than the bid. Works every time with large orders, and fast, but I may miss Schwab in this regard. I even tried 14,500 shares all or nothing, 13 minutes before the close, sell, at 3/8ths above the ask---four days ago---and it worked like a charm. So I have a problem. I do not want direct access to any floor. I want to hire a broker, but hold them to such tight limits, that their commission is not relevant. Block trading, on heavy margin, and then adding shorting leap calls. |
