TickChart Indicator plots the tick line on the main window of metaTrader.
In the Lite version, the number of ticks is limited to 20 and the alert function described below is omitted. 

The "tick-line" shows the most detailed, fastest and real-time activities of the market, which are usually hidden in bars or candles longer than 1 minute. Usually, several new tick-line segments appear while a bar of M1 time frame is completed. After the release of an important economic indicator, the number of ticks per bar may exceeds 100.

This indicator overlays the tick-line on normal chars in the main windows. Although usual charts are in "time-price" space, the tick-chart is in "tick-price" space, that is, the X-axis of tick chart is not the time. When market is very active, the X-axis of tick-chart advances fast and vice versa.

TickChart indicator is useful in many situations. For example,

• A tool for scalping : You can find several chances in a minute
• Find chances in the turbulence after the release of importance economic indicators: The tick-chart shows the detailed price changes hidden in a long long bull/bear candle
• As an electro-cardiogram of market: The pace of tick-chart segments generation indicates how vital the market is
• Multi-time-frame market watch: For example, you can see the tick chart and M15 time frame chart on the same window. This indicator overlays the shortest time frame, the tick.
• alert of significant price changes: Send an email and/or notifications using RSI and Envelope deviation.

There may be more usages. If you find a nice one, please let me know.
