Just check one minute charts of almost all stocks after you changed shorting only on uptick rule. You will see gaps in the charts on almost all stocks both in the downtrend and uptrend of stocks. Compare the charts for all stocks prior to your change of rule and you will find almost none or few gaps in one minute charts for the same stocks. Your rule change has been one major instrument in increased volatility of almost all stocks. Thanks a lot SEC
