1. Correct, stocks are only included when they have traded. 2. All stocks start in a neutral state and are not included. The first trade of the day is compared against the prior days settlement price. If it is unchanged, then it would still not contribute to the tick count. 3. As a stock trades, each tick is compared to the previous tick for the that stock. The result is an up tick, down tick, or no change. The tick count is then updated based on the prior tick state and the current tick state. For example, if a stock changes from down tick to up tick, both the down ticking total and the up ticking total need to be updated resulting in the net ticks moving +2. In the case of trading at the same price the tick direction is maintained in the same state, and so there is no change to the tick counts.
