Greater Less

IsGreater/IsLess predicates generate a signal if a value of series is greater(or less) than a given number at the current moment.

Implementation and Usage

These predicates can be used in a strategy with the following constructors:

IsGreater

IsLess

creates new instance of the IsGreater / IsLess predicate with default zero value.

IsGreater(Double)

IsLess(Double)

creates new instance of the IsGreater / IsLess predicate with the given value to compare.

The value of the indicators is updated by simple prototype of method Add():

Add(Double)

Add(Double, DateTime)

Use

Greater

Less

properties to get the current value.

Example

The example of IsGreater predicate for Apple Inc. stock price(Bar close price) with level of 235.5.
