Now, the signs used to illustrate price are a bit more complex. Price signals are made by extending a single hand in front of the body. Also, price signals are only used to reference the final digit of a bid or offer. Here are the basics: - **Digits 1-5:** For numbers one through five, fingers are held straight up as needed. As an example, a two resembles a traditional “peace” sign; three is an “OK” sign; the thumb is tucked into the palm for a four and untucked for a five. - **Digits 6-9:** For numbers six through nine, the hand is held parallel to the floor (sideways). The signals from 1-4 are repeated, only sideways. - **Even (0):** To represent a zero, a closed fist is used. Finally, trading floor hand signals are used to indicate the trade’s quantity or the number of contracts being bought or sold. These gestures combine the pricing signals with a touch of the face. The progressions below are used to signal quantity: - **1-9 contracts:** To buy or sell 1-9 contracts, the applicable price signal is touched to the chin. For instance, to buy or sell a five lot, the chin is touched by a straight-up open hand. - **Multiples of 10:** To buy or sell contracts in blocks of 10, the applicable price signal is touched to the forehead. For instance, to buy or sell a 10 lot, a single, straight-up finger is touched to the forehead. - **Multiples of 100:** To buy or sell contracts in blocks of 100, two steps are necessary. First, the applicable price signal is flashed near the forehead; second, a closed fist is touched to the forehead. For instance, a 500 lot is signaled by first flashing an open hand near the forehead and then touching a fist to the forehead.
