# Or

From MultiCharts

A logical (Boolean) operator that returns True if one or both of its operands are true. Logical operators are used in logical (Boolean) expressions that operate with true/false values.

## Usage

`E1 Or E2`

Where:

**E**- true/false expressions.

## Notes

- If one of the true/false expressions evaluates to True, the whole expression is evaluated as true due to the
**or**logical operator. For example:

(10 > 1) or (10 > 20)

- Will evaluate to True since the first expression is true, even though the second expression (10 > 20) is false.

- The whole expression is evaluated as true if
**only one**of the individual expressions evaluates to true. For example:

(10 > 100) or (100 < 2000) or (21 = 1)

- Will evaluate to True since the second expression (100 < 2000) is indeed true.

- See And for logical
**and**true/false expressions.

## Examples

2 = 1 Or 2 > 2

Will return a value of False.

True Or False Or False

Will return a value of True.
