Is Number Block

The Is Number Block determines if a value is a valid number, as follows:

  • Returns TRUE if the input is a valid number.
  • Returns FALSE if the input is a NaN (Not A Number). This value is recognized as 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.
