# Holidays

For each exchange you can define the list of public holidays, i.e. the dates on which the exchange is closed. The list affects data loading and charts displaying.

#### **Access holidays lists**

You can access holidays lists in one of the following ways:

**1.** From *Overcharts main window* >***Instrument*****s**Tab > ***Holidays***button

**2.** From *Overcharts main window* > ***Instruments*** menu > *Holidays*

#### **Create or Modify an holidays list**

To create/modify an holidays list:

**1.** Access holidays list

**2.** Select the list to edit and press **Edit** button, or press **New** button to create a new one

**3**. Define the list **unique name**

**4.** Add/Edit the holidays by pressing the corresponding button in the configuration window.

*For each holiday, set or change the following properties:*

**Date**: Represents holiday date

**Type**: Represents the filter type to apply to the data on defined date. Possible values:

- ***Full Session***: filter is applied to the entire session even if the session is split between two days (eg. CME)
- ***Full Day***: filter is applied from 00:00 to 24:00 of defined date
- ***Late Open***: indicates a change in the session start time on defined date
- ***Early Close***: indicates a change in the session end time on defined date
- ***Range***: represents a range of hours within the defined date

**Starting Time**: Represents the late opening time or range start time

**Ending Time**: Represents the early closing time or range end time

**Description**: holiday description (eg: Christmas)

**Repeat date for x years**: By indicating an integer value between 1 and 10 you can massively enter the date for x consecutive years

#### **How to use it**

You can **set** the holidays list:

1. ***In the exchange configuration***: in this case, all instruments belonging to the exchange will inherit its holidays list by default.
2. ***In the chart configuration***: in this case, the holidays list will only affect the chart loading / displaying.

***Overcharts already contains some preconfigured holidays lists. Preconfigured-lists properties can be modified by the user, but if you modify them, any future property updates will NOT be applied.*
You can restore the default configuration of a preconfigured list at any time by selecting the list from holidays lists and pressing the **Restore Standard** button.**
