Financil Contracts (FCs) specify rights and obligations that parties are legally bind.Hence effective management of FCs is vital.Domain Specific Language (DSL) approach provides a method of defining rights and obligations of contracts using fixed and precisely defined set of combinators and observables.As a result, any contract can be composed using fixed set of symbols, the contract management becomes efficient and effective.The Haskell Contract Combinator Library (HCCL) is the driving forcebehind the DSL approach in finance sector

- Research Hypothesis ================ Rule is a finance Contract -> Daily margin calculation
- Up to this point, (4) we have seen How FM evolved What kind of Derivatives are trading Stakeholder Groups and Interests Risk High Economic Segment Contract Mgt is Important Computer Science is Promising
- The example contract that we choose in our research is this. The contract is , selling 100 dell shares, for 4800 GBP at future date 240
- When analyzing the above contract, we can clearly see to major parts. major parts: buy and sell + do nothing (mee slide eke kiyanna, methane contract 2k tiyanawa kiyala) Building block of the previously defined contracts Futher, we can see, there are two contracts in the this contract as well, selling 100 Del and reciving money
- Option Contract , clearly see the two options
- Describing the rights and obligations of contracts evertime when needed, is a tedious task (repeating number of shares, amount to be paid, share type). Complex ones may be even more harder. So, via a name it’s easy to introduce a contract Instruments Easy way of introducing to the market. In Haskell we can define data type as follows: Data type name | Data tye constructor From this way we add the defined contract to a new context called, Instrument. The defined contract is introduced to the market in the form of an instrument. Market players knows the inherent properties of this instrument, the commodity, number of shares traded. At this point we created our Instrument.
- Market participant would willing to pay for the instrument Cash flow – Now, we have an instrument in the market , also a buyer who is willing to pay option premium to purchase the instrument.
- Option Writer (Seller) – Introduce Instrument to Market Buyer – Pay the Premium And Purchase The Option Buyer Is The OWNER Of Instrument ========================= Here we are dealing with two data types, Instrument and Option Premium , to represent this trade we create another data type called trade.
- This trade is brings to CCP To represent this trade, we created a new data type called Trade Trade data type takes, has the value constructor Trade, that takes two input arguments, The first argument is of data type Instrument. The option premium paid 200 GBP and Instrument ABC is wrapped in this data type Trade.
- LET’S LOOk at the rights and obligations specified in this trade. The owner of this ABC instrument has following rights and obligations. Since he purchased the instrument by paying option premium. Owner has the right of selling, 100 Dell and receive 4800 GBP from option writer. =========================== But default risk is there, CCP undertake this risk by novating the above contract and acting as the middle party.
- Now the both buyer and seller deals with , CCP. Here CCP act as the seller to original buyer and buyer to original seller. At this time CCP regulations open a state called Long Position to Buyer and state call Short position to Seller. That is the legal requirement. Now buyer and seller treat sepeartely.
- How we did in our research. We create the data type trade to incorporate the scenario of , purchasing instrument by paying Option Premium. Our research we use HCCL and Haskell to their optimum level. We use Haskell pattern matching technique to extract the needed results. For example, to obtain the instrument from trade, we defind function as follows, Similarly to obtain option premium, we defined function getInstrumentPremiumFromTrade function. Accordig to the pattern specified in the function, it retrieves Instrument, this function contract
- In design phase we identified, it is needed to identify inputs for the rule from the original contract/trade. This analysis is carried our for that. Similarly defining set of functions and following Haskell pattern matching technique, we extracted following from both Instrument and Option Premium. For example, the underlying equity, Del, maturity date, 240 , With in bracket I specify the , data type of the corresponding values.
- Th

- Absence of a DSL – Separate mechanisms are there to represent each contract Drawback -> When a new Derivative comes to the market, it’s again need to create new mechanism to represent it.

There n Concrete Implementation – Model, model incorporate the time factor, (model models an observable) Model -> Forex Mode, Interest Rate Model
- Entire Value Process in a nutshell Here two main important point, What are evaluation semantics Model
- Model – models an observable that is an external to the contract over time. Model – y model is lattice ?, each node, a value in time, each step -> a point in time construction is solely depend on valuers intension, Compare the two
- Denotation is equivalent to Value Process in Peyton Jones Research, This research -> discussed in views of SE Language approach Model value process mathematically Denotation Observables – Value of unknown Observable -> to its time values Example – Int rate fluctuations over time model in mathematically Unknown observable – S – Int rate Time – N (natural number V - Set of values Trhough a model, set of values at each time step. Denotation of Contracts -> Contract – series of cash flows Through a model , contract values at each time point. (Domain D of the Denotation of Contracts)
- The information generated from Denotational Semantics will be used for symbolic contract mgt. Contract Mgt: Equivalence – 2 different contracts, semantics are total – same cash flows Inferring Properties – Deduce properties from denotational semantics Transformation: - Transform to much smaller contracts At denotation – Different contracts at different time periods management more easy (simpler contracts)
- Specialization -> As time progress -> more info about environment -> more accurate -> replace environment -> better management C contract specialized to f(c,rho) -> but will give same cash flows as C, we can replace C with F(c,rho) because more infor better management Reduction – Advance contract by one period -> the total contract semantics = semantics of C at period 1 + semantics of contract C’ over (n-1) time
- We scale values of type “Double” Computations : lift lift2
