I found this quote from a website: "The tick indicator is a number which comes out several times each minute during the trading day. It shows the total number of NYSE (New York Stock Exchange) stocks, at that given instant, that are trading higher than their last price minus the number that are trading down. If 1800 are on uptick and 1200 on downtick, the number would be +600. Readings between +/- 400 are considered neutral, readings of +/- 1000 are considered extreme. On rare occasions, readings like +/- 1500 may be seen, but this is very unusual. We plot this number as a green line below the price bars (see chart above). There are several way to use the Tick indicator, but one of the most primitive is simply to think of it as the "gas pedal" for the market. If ticks are +800, that shows a lot of buying power is currently going into the market. This would be a bad time to buy because that power is likely to soon exhaust itself and price may fall. The way we use this indicator is to look for a trending market, and to enter when ticks retrace near 0." What is the symbol or name for this Indicator???
