• question 2: after first quick look I had across functional objects involved/composed together for eventually calculating the FloatingAmount and I could see lot of input are “external input” thus not being resolved from the Payout path values per se… that is to say there is no automation processing here because an extern

  • meaning there is actually no automation processing
    because there are gaps to manually fulfill, whereas should be resolving per functions, between Event model where agreements on terms is represented and related Process model based on “func” objects for the purpose of automating the execution of the Event model… as far as I can understand at this stage… if so, how to assess exactly where we stand in regards of target where ideally would have fully smart implementation i.e. “Trade -> Fixing -> “func” -> Calculation results” ?
