Trading Volume Formula. If you are an affiliate, the number of equity securities you may sell during any three-month period cannot exceed the greater of 1% of the outstanding shares of the same class being sold, or if the class is listed on a stock exchange, the greater of 1% or the average reported weekly trading volume during the four weeks preceding the filing of a notice of sale on Form 144. Over-the-counter stocks, including those quoted on the OTC Bulletin Board and the Pink Sheets, can only be sold using the 1% measurement.
