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 Refresh Rate (ms): specifies the frequency (in milliseconds) for real-time data processing/updating. The lower the value in milliseconds, the higher the frequency of updates and graphical refresh. The value should be chosen based on your PC’s performance! We recommend NOT going below 50 ms.
If you notice slowdowns or delays in the updating of charts, it is likely that your PC is not powerful enough to handle the required processing (both in terms of calculations and graphical refresh). In such cases, the appropriate actions are:- Reduce the number of charts, DOMs, indicators, and workspaces being used.
- Increase the milliseconds for 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).
