Preferences

Preferences window contains global Overcharts settings. You can access the Preferences from Overcharts main window > Tools menu > Preferences.

Below, the available properties divided by sections.

Platform #

Environment

• Theme: specifies the platform main layout (colors, objects, etc.).

Performance

• Data refreshing rate (ms): specifies the frequency (in milliseconds) of processing / updating real-time data. The lower the value in milliseconds, the higher the data and chart update frequency. The value in milliseconds must be chosen based on your PC performance. If you notice slowdowns or delays in updating charts, DOMs etc., your PC is most likely not powerful enough to support the required processing (both in terms of calculation and graphics refresh). In that case, the right thing to do is to reduce the number of charts, DOMs, indicators, workspaces used, increase the milliseconds of the data refresh rate, reduce the number of applications running on the same PC.

Instrument #

Data Series

• Bar Timestamp: specifies whether bar timestamp (in charts, data series, etc.), represents the beginning or the end of bar. For example, in a 5-minute bar (from 10:00:00 to 10:04:59), 10:00:00 represents the bar’s start-time, and 10:05:00 the bar’s end-time. This value affects all charts and data series.

Trading #

Confirmations

Using the properties in this section you can enable / disable confirmation requests when placing / modifying / canceling an order or when closing or reversing a position. If enabled, Overcharts will display a message and wait for your manual confirmation before proceeding with the requested operation.

Notifications

Using the properties in this section you can enable / disable the sounds played following events such as: filling, cancellation, modification (failed) or placing (failed) of an order.

Error / Warning Messages

Using the properties in this section you can enable / disable the error / warning messages shown following the occurrence of certain events.

Colors

In this section, default colors of order types, positions etc. are defined.

Chart #

Window

• Tab Name: specifies the text (default formatting) to be displayed in the chart Tab within the Workspace. You can format the Tab name using available tags and/or inserting any type of text. If necessary, you can also change the Tab name directly on chart (the value specified here is only a default).
  Available Tags:
  • @INSTRUMENT_NAME: instrument name
  • @INSTRUMENT_SYMBOL: instrument symbol
  • @RESOLUTION: current chart resolution

Example:
Specifying the format: @INSTRUMENT_SYMBOL [@RESOLUTION]
Tab name for ESZ23 instrument on a 30-minute chart will be: ESZ23 [30 Minuti]

• Backfill on reconnection: specifies whether to automatically backfill chart data following a temporary data-feed disconnection + reconnection. Backfilling data can take a long time. If trading is enabled on chart, it may be a problem to wait for the backfill to finish to continue trading. For this reason, it is very often preferable not to update charts rather than not being able to trade.
  Three possible options:
  1. Never: backfill is NOT automatically performed. A warning message is displayed on chart status line. To perform the backfill, use chart manual refresh (chart window > Maintenance menu > Refresh).
  2. Only if Trading is NOT enabled on Workspace: backfill is automatically performed only if trading is NOT enabled on Workspace.
  3. Only if Trading is NOT enabled on Chart: backfill is automatically performed only if trading is NOT enabled on chart.

• Mouse Wheel Sensitivity (on chart): defines the mouse wheel sensitivity on chart. The higher the sensitivity, the faster the zoom will be.

Alert #

In General (defaults) and Actions (defaults) sections some default values are specified to be used when adding Alerts to the chart.

Privacy #

Trading

• Show Account Name / Code: if checked, trading account name or code is displayed in clear text on platform. If NOT, display is partial (e.g. *******3454).
