You can graph the value of any portfolio over time by doing the following:
Depending on the size of your portfolio and the time it has existed, this might take a while as Venice has to load in stock quotes for every stock traded for every day of the portfolio.
Apart from graphing the value of the portfolio over time, you can also graph the profit/loss of the portfolio. To do this, graph the portfolio as above, then click on the menu item with the same name as your portfolio, then select the Graph menu item and then click on Profit/Loss. The profit and loss graph is calculated by ignoring any deposits and withdrawals made to the portfolio, the balance of that portfolio over time will reflect the profit and loss made.
A market indicator is an indicator that can be used to help determine the state of the market. They are calculated using multiple stocks on the market, for example Advance/Decline uses all ordinary stocks in its calculations.
Currently the only market indicator that Venice can graph is the advance/decline indicator. You can graph this indicator by:
This operation reads in almost all of the available stock quotes, so it may take a while.
The advance/decline indicator is calculated by taking an arbitrary start value (currently 0). Each day's value is calculated by taking the number of stocks that advanced (i.e. have a higher day close than day open) minus the number of stocks that declined and adding that to the previous day's value. This creates a cumulative graph whose trend may be used to give an indication of possible future direction of the market.
Venice supports a variety of technical charts. Some of these charts are described below, for the others, please consult the literature for their meaning and interpretation.
Venice supports the charting of user-defined custom indicators. Using the Gondola Language you can write custom indicators which can then be charted. The custom chart user interface allows you to enter a Gondola equation to chart and to specify the chart as either primary or secondary. A primary chart is one that appears in the top graph. A secondary chart will appear in its own smaller graph below.
The Point and Figure graph attempts to highligh only significant price movement, independant of time. This means it differs from most of the other charts in that there is not necessarily any data shown for a particular date range.
If you switch to the Point and Figure graph while zoomed in on an area which does not have any Point and Figure data or you attempt to zoom in on such an area, a warning dialogue is displayed and the operation will be cancelled.
The Fibonacci Retracement Chart is used to estimate possible support and resistence levels between two price levels. This indicator draws horizontal lines at levels corresponding to the following Fibonacci Ratios: 0%, 23.6%, 38.2% , 50.0%, 61.8%, 78.6%, 100%
The Fibonacci Chart takes two parameters:
If your data source doesn't automatically adjust your data for dividends or splits, you may wish to display the chart as if no split or dividend occurred. Or alternatively, you can display the chart as if the split happnened when the stock listed. You would want to do because indicators may be misleading Gondola rules may trigger unexpectedly.
To adjust the chart for a split or a dividend, select the 'Adjust Chart for Split/Dividend' menu item, which can be found in the chart window, under the menu of the stock being graphed.
An "Adjust Data" dialog appears with the following fields:
For the direction field, choose forward if you want to display the chart as if the dividend or split hadn't occurred. Choose backwards if you want to display the chart as if the change had always occurred.
Enter the details of the split or adjustment and press OK. The chart will redraw itself and display the chart according to the change.
To apply a reverse split of say one for two, you would enter 0.5 in the ratio field.
The graph functions are accessed via the toolbar which is created on the left of the chart by default. The functions are:
The "Zoom in" function will zoom in on a selected area, where as "Zoom out" always returns to the intial setting, regardless of how many times the user zooms in.
The chart drawing functions allow the user to draw lines and add text to a chart in a fairly basic manner. Any lines drawn on a chart scale with the zoom level.
The "Clone" button opens a window with the same chart type.
The "Flip chart" button toggles the orientation of the chart. The initial orientation is for the origin of the chart to be in the top left hand corner. Therefore, pressing the button twice returns the chart to it's original position.
When you hover the mouse over a graph region, a tooltip appears showing the quote value under the pointer. If however you require a more immediate or accurate view of the data, Venice can display a cursor on the chart.
Enable the cursor by selecting 'Enable/Disable Chart Cursor' in the Graph menu. When you enable the cursor, it is drawn on the chart, and table opens up with a row selected which corresponds to the cursors location on the chart.
When you select a different row, the cursor will appear at that location on the chart. When you move the cursor on the chart (using the mouse), the table will select the row which corresponds to the cursor's new location.
