Note:
  1. The TPEx will adjust the margin purchase leverage ratio and short sale margin by 10% (+/-) in response to intense share price volatility, irregular trade volume, or concentrated equity. If these conditions occur simultaneously, the margin purchase leverage ratio will be reduced by 10%, and the short sale margin will be increased by 10%.
  2. During two or more times dispositions period, the TPEx may reduce the margin purchase ratio to zero and raise the margin percentage for short sale by 10%.
  3. The TPEx Surveillance Operations Oversight Committee may also change these ratios as stated above.
  4. If, conditions occur at the same time, the relevant margin percentage for short sale may be further raised while the margin purchase ratio remains zero.
