I've gathered a few points which expose that Penson's behavior could actually be considered ILLEGAL. It started with their recent penny stock policy change caused by NSCC illiquid requirement.
1) Zecco's reaction to Penson's policy has been to restrict the maximum order size allowed down to 25% (now 10%) of 20-day Average Daily Volume. By adopting such measure, the volume of sub-$1 stocks can be indirectly MANIPULATED DOWN TO OBLIVION. It would only take either of two cases (which can also happen simultaneously): - When a penny stock's active traders hold their shares on Penson-clearing brokers. - When a penny stock has days or weeks of little or no activity (extremely typical on the OTCQB and Pink Sheets).
The order size restriction to a maximum 10% 20-day ADV inevitably causes tradeable order sizes to shrink every day with a strong possibility of becoming even zero. 2) Although thinking it well, it's a nice way for Penson and its related brokerages to rake up EXCESSIVE COMMISSIONS by requiring traders to place orders over multiple days to liquidate a position.
3) At last, one could say that the case of a share buy-back where shares you've recently sold are put back into your account by the clearing firm because-they-say-so can be a form of UNAUTHORIZED TRADING.
What do you think? What could I do with such info?
