CL: Close
PREV: Yesterday's Close
OP: Open

Explanation
This scan is based on the TD%F described in Thomas DeMark's book DeMark on Daytrading Options. First, you should create a quotepage of call options which are just slightly "in-the-money" and very near expiration. Then create a Scan which runs on this newly created options quotepage, with a "Daily" periodicity, and with the simple signal below. When an call options reaches this level, DeMark considers this an entry point. This scan should be run frequently throughout the trading session. The signal finds options whose current price is between 48 and 55 percent of the previous days closing price. The option must not open below 55% of the previous days close. A similar signal for put entry is also shown below.

Signal
