How does one cross 100K of stock within the same trading house without the ask price showing up. I noticed that the bid ask remained .155 - .175 with the bid / ask being about 10K - 7500 shares. Is this a sale for tax purposes. Recognizing that rules are rules is this a tax loss sale that keeps the shares within a arms length of the trader even though supposively this would violate the 30 day rule.
