Sessions, Holidays and Properties

Information on basic data properties, sessions, time zones and holidays are usually offered by the data provider together with the quotations. However, the data may contain errors - for whatever reason - or the data may cause unwanted side effects in your trading system or the chart display. For cases like these, Tradesignal offers you the possibility to add missing information or even overwrite the delivered data. Use the editing for:
  • Adjusting currency data to your working hours
  • Adding the right trading times (sessions) to quotations
  • Adding time zone information for quotations
  • Adding missing holidays or other days without trading

Modify Sessions and Properties Window

The window for editing the sessions, holidays and properties can be called up for an instrument (a symbol). This can be done in a Chart, or from a selected row in the Scanner, Watchlist or Portfolio. You can open the window in two ways:
  • Click on the Sessions button in the Home > Data group on the Toolbar.
  • Alternatively, right-click on the chart legend or the selected row and choose the option Show Session Manager in the context menu.
The window opens. The name of the currently edited instrument is displayed in the window header.

Defining Sessions

Session Manager, Tab Sessions
On the tab Sessions you can set up which times should be used for trading. You have two options:
  • Use session information from the data provider - Select this option if you want to use the information delivered by the provider. E.g., the trading hours of the NYSE are 9:30–16:00 local time.
  • Use session information defined below for all charts displaying this instrument - Select this option to set up your own trading times for a symbol.
The trading hours are displayed as blue areas in the session display. Move the mouse over the cells to see which time range they represent.

You can select the trading hours as follows (repeating the actions removes the selection again):
  • Click on the name of each weekday to add (or remove) complete days from the selection.
  • Keep the mouse button pressed and move the mouse over the upper edge of the session display to select a time block, e.g. 08:00 to 15:00.
  • Click on a column header to select a cell column.
  • To define session times to the minute, right-click a cell and select another start time from the list.
  • To select a continuous region, keep the mouse button pressed while moving over the cells in the session display.
You can select a Time Zone for which the quotations are displayed. This setting is important when you are using external quotations from distant exchanges and the original data does not include the time information. You can also set the time zone when defining external data sources (see the chapter Data Sources); however, in this case the settings affect all data in the defined folder, even when they do not belong to the same time zone.

When you want to display trading information after the official end of the session without new bars/candles being generated, select the option Session Extension. Enter a number of bars or click on the small arrows to enter the numbers. The information for high, close, low and volume are added to the last bar. When you select the additional option Disable volume cumulation in session extension period, only the prices, not the volume are added to the last bar.

Define Holidays

Session Manager, Tab Holidays
On the tab Holidays you can define which holiday options should be used. There are two options:
  • Use holiday information from the data provider - Select this option to use information delivered by the provider. (Note: not every Dataprovider delivers holiday information)
  • Use holiday information defined below for all such instruments - Select this option to enter holidays. You can define any day as "holiday", i.e. day without trading activity, for example bridging days.
To add a new holiday, click on New. A dialog opens. To enter the date, click on the arrow button to open a calendar in which you can select a date. Then enter a name for the holiday.

To edit a holiday, select it in the list and click on Edit. A dialog opens in which you can edit the date and/or the name.

To delete a holiday, select it in the list and click on Delete.

Edit Security Properties

Session Manager, Tab Properties
On the tab Properties you can change four settings for the instrument data. This is especially useful when the external data does not include this information. As default, the Standard settings are selected.

Instrument Name - Here you can change the name of the symbol as displayed in the chart.

Lot Size - The Lot Size is the smallest number of pieces traded, for example 100 pieces for a security. For futures, it is usually 1 piece. To simulate a leverage effect that is caused by multipliers, you can edit the lot size. For the Dax Future that would be 25 Euro, for the Bund Future 1000 Euro.

Tick Size - There you can change the smallest possible price movement of a security. For stocks and some indices, it is 0.01 Cent. For some futures it is 0.5 points, for other futures 0.01 ticks or for currencies 0.0001 pips.

Display Unit - Here you can change the smallest unit of the value scale.
