  • Type: algorithm.[datamining/tradingsignal]

  • Location: algo.[algorithmname]

  • Inputs: inputlist

  • InputConstraints: inputconstraint[;]

  • Outputs: outputlist

  • OutputConstraints: outputconstraint[;]

  • Activities: Register the algorithm

  • Permissions:

-  (part_of (A, B) part_of (B, C)) part_of (A, C)

  •  (substitute_to (A, B) substitute_to (B, C)) 

  • substitute_to (A, C)

Rule 4.

-  (A AND B), B ::= substitute_to(A, B)

A OR B, the resulting output is A or B

Rule 5.

-  (A AND B), B ::= disjoint_to(A, B)

A AND B, the resulting output is A and B
