The IsNumber Block determines if a value equals a valid number.
- will be TRUE when is a valid number.
- will be FALSE when 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 (i.e. Order Block, ASE 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.
