  2. When on a given day, the percentage of premium on a TDR announced through the MOPS for the preceding business day is in excess of 30 percent, while its closing price for the given day is also the highest of the most recent 6 business days (inclusive of the given day), provided that if there is no closing price for the most recent 5 business days (excluding the given day), then the closing price for the given day must also be higher than the opening reference price.
