The chart window shows graphical representation of one financial instrument in real time. It can display a historic plot of the price together with an indefinitely large number of technical indicators.

Figure 1. Example chart window.

1. Several technical indicators (MACD, Moving Average, Volume).
2. 15-min chart of EURUSD rate (Euro-US dollar). This example is drawn as Japanese candles.
3. Fibonacci lines (arc).
4. A legend for each chart. The legend is built as NAME(PARENT_NAME), where NAME - is the name of this chart, and PARENT_NAME is the name of the parent element. This example shows the legend for EURUSD rate as EURUSD(M15), where EURUSD - instrument ticker, and M15 means 15 minute chart. Indicator MACD has a legend MACD(EURUSD(M15)), i.e. chart name "MACD" with the parent "EURUSD(M15)". Indicators can be based not on the primary instrument only (EURUSD as shown), but also on each other.
5. Trendline.
6. Control pannel for setting the instrument and the chart period.
7. Floating help. It pops up when the mouse cursor is held over the chart longer than one second. The help usually shows the chart legend ("EURUSD(M15)" in this example), time and values of the bar in that point.
8. Scroll bar for choosing the visible part of the chart.
9. Clone button for creating a copy of this window

The horizontal axis shows time. Time is shown as hours:minutes, day-hours:minutes or day-month.

Vertical axis shows the value of the chart on a linear scale (as opposed to logarithmic).

The chart can be controlled through the control pannel (6), (8), (9), as well as by pressing a right mouse button on various chart elements.
