Description
This indicator saves your chart objects including indicator area objects and load it automatically when you re open the chart or manually if you press the hotkeys for loading the saved chart objects.
Saving
It works in both auto and manual, the auto save has two different modes:
- OnChange: When an object is added/removed/changed it saves the chart
- Interval: Keeps saving the chart based on a time interval you set
To manually save your chart objects you just have to press the hotkey you set for manual save, the default hotkey for manual save is Shift+S.
You can also save the chart objects on a file that you select, the save as function allows you to save the chart objects on any file you want to, it has an hotkey like manual save, the default hotkey for save as is Shift+A.
Loading
Indicator saves the chart objects on your system cAlgo folder, the path to saved chart files is: documents/calgo/charts
Each saved chart has it own ".cchart" file, the file name is in this format: AccountNumber-SymbolName-TimeFrame-ChartType.cchart
By using the above naming format indicator keeps each of your charts separate on their own files.
To load a saved chart you can use either auto load, manual load, or open as functions.
If you enable auto load indicator will load the chart objects from its saved file whenever the indicator initializes.
The manual load function allows you to load the chart whenever you want to, you just have to press the manual load hotkey, the default hotkey for manual load is Shift+L.
You can also open a saved chart file by using Open as option like Save as option, just press the Open As hotkey and select the chart file you want to load.
It has an hotkey for opening the charts folder on your file explorer, to open the folder press the "Charts Folder Hotkey", it will automatically select the current chart file if there was any.
When setting hotkeys be sure it will not interfere with cTrader hotkeys, otherwise the hotkey will not work.
