IsNumber block
Is Number block
The Is Number block determines if a value is a valid number, as follows:
- Returns TRUE if the value on the input port is a valid number.
- Returns FALSE if the value on the input port is NaN (Not A Number). This value is considered an invalid value in ADL.
If you use a NaN value as an input to any smart trading block, such as an Order block, the block will not create a new order. If the block is instructed to modify an existing order to a price or a quantity of NaN, it will simply delete the order.
