A chart can display more than one symbol. You can insert additional symbols into separate chart panes, or overlay them in the same chart pane. You can also change or replace the symbol that is displayed in a chart.
If you later want to remove one of the additionally inserted symbols, you can do so by removing them from the chart (see Removing Symbols), or temporarily hiding them (see Customizing Chart Objects).
▪ Right-click in the chart pane below which the symbol should be inserted and choose Insert > Symbol.
▪ In the Symbol Search dialog, enter your search term in the first field on the left side and change the search settings, if necessary. For more information, see Searching for Securities in the Symbol Search Dialog.
▪ Click on the green button or press the Enter key to start the search.
▪ Select the symbol that you want to insert.
▪ Click OK. The symbol is inserted in a new pane below the selected chart pane.
Note If the chart pane that you have selected in the first step is empty (contains no symbols or other chart objects), then the new symbol is inserted into the active empty pane instead of into a new pane.
Note You can also create a chart with overlaying symbols by for example selecting several symbols in a price page and holding the Ctrl key while opening them: See Opening Symbols from Existing Documents for details.
▪ Right-click in the chart pane into which the additional symbol should be inserted and choose Insert > Overlay.
▪ In the Symbol Search dialog, enter your search term in the first field on the left side and change the search settings, if necessary. For more information, see Searching for Securities in the Symbol Search Dialog.
▪ Click on the green button or press the Enter key to start the search.
▪ Select the symbol that you want to insert.
▪ Click OK. The symbol is inserted in the same chart pane, overlaying with the already displayed symbols.
Note
The price scale in overlaid charts will always be defined by the main symbol of
the chart (usually the first symbol that you have added). If you want to use
another symbol as the main symbol, click the time series of this symbol and then
click the To Background 
button on the Drawing toolbar.
If you want to show the prices
of two overlaying symbols on different price scales, you can connect one of the
overlaid symbols to the second price scale, which will be displayed on the left
side of the chart. See Inserting a
Second Price Scale.
Note When the option Activate study color inheritance on overlaid charts is selected under Tools > Options > Chart, coloring for all symbols in a chart pane will change from Multi Color to Single Color mode as soon as a chart contains overlaid symbols. This means, that regardless of selected chart type: e.g. Candlestick, OHLC, Line etc. each data series will be displayed with only one color. See Chart Settings.
There are several possibilities to change or replace the symbol that is displayed in a chart:
▫ Overwrite the symbol with a new symbol: Just start typing in the chart pane of the symbol. For details, see Calling Symbol Search from a Document.
Note If the chart pane contains more than one symbol, the first symbol will be replaced.
▫ Use the Change Symbol dialog, see Changing Symbols.
▫ Copy a symbol from another document with drag and drop to replace the current symbol. You have to drop the new symbol exactly on the existing symbol to replace it – the mouse pointer will lose the plus sign in this case. For details, see Copying Symbols.
See Copying Symbols. You can of course also copy symbols between charts.
Note When you drop a symbol on a chart, it will be overlaid if you release the mouse button inside a chart pane, and inserted when you release the mouse button on a pane header. If you drop it exactly on an existing symbol, this symbol will be replaced by the new symbol.
