A CFD is a tool of leverage with its own potential profits and losses. It allows an investor to enter the global trading market without directly dealing with shares, indices, commodities or currency pairs.

CFDs were originally developed in the early s in London as a type of equity swap that was traded on margin. They were initially used by hedge funds and institutional traders to cost-effectively hedge their exposure to stocks on the London Stock Exchange , mainly because they required only a small margin.

Moreover, since no physical shares changed hands, it also avoided the stamp duty in the United Kingdom. In the late s, CFDs were introduced to retail traders.

They were popularized by a number of UK companies, characterized by innovative online trading platforms that made it easy to see live prices and trade in real time.

In the UK, the CFD market mirrors the financial spread betting market and the products are in many ways the same. However, unlike CFDs, which have been exported to a number of different countries, spread betting, inasmuch as it relies on a country-specific tax advantage, has remained primarily a UK and Irish phenomenon.

They are not permitted in a number of other countries — most notably the United States, where, due to rules about over the counter products, CFDs cannot be traded by retail investors unless on a registered exchange and there are no exchanges in the US that offer CFDs.

As a result, a small percentage of CFDs were traded through the Australian exchange during this period.

The advantages and disadvantages of having an exchange traded CFD were similar for most financial products and meant reducing counterparty risk and increasing transparency but costs were higher.

In October , LCH. Within Europe, any provider based in any member country can offer the products to all member countries under MiFID and many of the European financial regulators responded with new rules on CFDs after the warning.

CySEC the Cyprus financial regulator, where many of the firms are registered, increased the regulations on CFDs by limiting the maximum leverage to To support new low carbon electricity generation in the United Kingdom, both nuclear and renewable , Contracts for Difference CfD were introduced by the Energy Act , progressively replacing the previous Renewables Obligation scheme.

A House of Commons Library report explained the scheme as: Contracts for Difference CfD are a system of reverse auctions intended to give investors the confidence and certainty they need to invest in low carbon electricity generation.

CfDs have also been agreed on a bilateral basis, such as the agreement struck for the Hinkley Point C nuclear plant.

CfDs work by fixing the prices received by low carbon generation, reducing the risks they face, and ensuring that eligible technology receives a price for generated power that supports investment.

CfDs also reduce costs by fixing the price consumers pay for low carbon electricity. This requires generators to pay money back when wholesale electricity prices are higher than the strike price, and provides financial support when the wholesale electricity prices are lower.

The main risk is market risk , as contract for difference trading is designed to pay the difference between the opening price and the closing price of the underlying asset.

CFDs are traded on margin, and the leveraging effect of this increases the risk significantly. It is this very risk that drives the use of CFDs, either to speculate on movements in financial markets or to hedge existing positions in other products.

Users typically deposit an amount of money with the CFD provider to cover the margin and can lose much more than this deposit if the market moves against them.

If prices move against an open CFD position, additional variation margin is required to maintain the margin level.

The CFD providers may call upon the party to deposit additional sums to cover this, in what is known as a margin call.

In fast moving markets, margin calls may be at short notice. Counterparty risk is associated with the financial stability or solvency of the counterparty to a contract.

In the context of CFD contracts, if the counterparty to a contract fails to meet their financial obligations, the CFD may have little or no value regardless of the underlying instrument.

This means that a CFD trader could potentially incur severe losses, even if the underlying instrument moves in the desired direction.

OTC CFD providers are required to segregate client funds protecting client balances in event of company default, but cases such as that of MF Global remind us that guarantees can be broken.

Exchange-traded contracts traded through a clearing house are generally believed to have less counterparty risk. Ultimately, the degree of counterparty risk is defined by the credit risk of the counterparty, including the clearing house if applicable.

There are a number of different financial instruments that have been used in the past to speculate on financial markets.

These range from trading in physical shares either directly or via margin lending, to using derivatives such as futures, options or covered warrants.

A number of brokers have been actively promoting CFDs as alternatives to all of these products. The CFD market most resembles the futures and options market, the major differences being: Professionals prefer future contracts for indices and interest rate trading over CFDs as they are a mature product and are exchange traded.

The main advantages of CFDs, compared to futures, is that contract sizes are smaller making it more accessible for small trader and pricing is more transparent.

Futures contracts tend to only converge to the price of the underlying instrument near the expiry date, while the CFD never expires and simply mirrors the underlying instrument.

Futures are often used by the CFD providers to hedge their own positions and many CFDs are written over futures as futures prices are easily obtainable.

Options , like futures, are established products that are exchange traded, centrally cleared and used by professionals.

Options, like futures, can be used to hedge risk or to take on risk to speculate. CFDs are only comparable in the latter case. An important disadvantage is that a CFD cannot be allowed to lapse, unlike an option.

This means that the downside risk of a CFD is unlimited, whereas the most that can be lost on an option is the price of the option itself. In addition, no margin calls are made on options if the market moves against the trader.

Compared to CFDs, option pricing is complex and has price decay when nearing expiry while CFDs prices simply mirror the underlying instrument.

CFDs cannot be used to reduce risk in the way that options can. Similar to options, covered warrants have become popular in recent years as a way of speculating cheaply on market movements.

CFDs costs tend to be lower for short periods and have a much wider range of underlying products. In markets such as Singapore, some brokers have been heavily promoting CFDs as alternatives to covered warrants, and may have been partially responsible for the decline in volume of covered warrant there.

This is the traditional way to trade financial markets, this requires a relationship with a broker in each country, require paying broker fees and commissions and dealing with settlement process for that product.

With the advent of discount brokers, this has become easier and cheaper, but can still be challenging for retail traders particularly if trading in overseas markets.

Without leverage this is capital intensive as all positions have to be fully funded. Rokhlin Yale and L. This breakthrough paved the way to practical computation of the velocities from the vortex elements and is the basis of successful algorithms.

They are especially well-suited to simulating filamentary motion, such as wisps of smoke, in real-time simulations such as video games, because of the fine detail achieved using minimal computation.

Software based on the vortex method offer a new means for solving tough fluid dynamics problems with minimal user intervention.

Among the significant advantages of this modern technology;. The vorticity confinement VC method is an Eulerian technique used in the simulation of turbulent wakes.

It uses a solitary-wave like approach to produce a stable solution with no numerical spreading. VC can capture the small-scale features to within as few as 2 grid cells.

Within these features, a nonlinear difference equation is solved as opposed to the finite difference equation.

VC is similar to shock capturing methods , where conservation laws are satisfied, so that the essential integral quantities are accurately computed.

The Linear eddy model is a technique used to simulate the convective mixing that takes place in turbulent flow. It is primarily used in one-dimensional representations of turbulent flow, since it can be applied across a wide range of length scales and Reynolds numbers.

This model is generally used as a building block for more complicated flow representations, as it provides high resolution predictions that hold across a large range of flow conditions.

The modeling of two-phase flow is still under development. Different methods have been proposed, including the Volume of fluid method , the level-set method and front tracking.

This is crucial since the evaluation of the density, viscosity and surface tension is based on the values averaged over the interface. Discretization in the space produces a system of ordinary differential equations for unsteady problems and algebraic equations for steady problems.

Implicit or semi-implicit methods are generally used to integrate the ordinary differential equations, producing a system of usually nonlinear algebraic equations.

Applying a Newton or Picard iteration produces a system of linear equations which is nonsymmetric in the presence of advection and indefinite in the presence of incompressibility.

Such systems, particularly in 3D, are frequently too large for direct solvers, so iterative methods are used, either stationary methods such as successive overrelaxation or Krylov subspace methods.

Krylov methods such as GMRES , typically used with preconditioning , operate by minimizing the residual over successive subspaces generated by the preconditioned operator.

Multigrid has the advantage of asymptotically optimal performance on many problems. Traditional [ according to whom?

By operating on multiple scales, multigrid reduces all components of the residual by similar factors, leading to a mesh-independent number of iterations.

For indefinite systems, preconditioners such as incomplete LU factorization , additive Schwarz , and multigrid perform poorly or fail entirely, so the problem structure must be used for effective preconditioning.

CFD made a major break through in late 70s with the introduction of LTRAN2, a 2-D code to model oscillating airfoils based on transonic small perturbation theory by Ballhaus and associates.

CFD investigations are used to clarify the characteristics of aortic flow in detail that are otherwise invisible to experimental measurements.

To analyze these conditions, CAD models of the human vascular system are extracted employing modern imaging techniques. A 3D model is reconstructed from this data and the fluid flow can be computed.

Blood properties like Non-Newtonian behavior and realistic boundary conditions e. Therefore, making it possible to analyze and optimize the flow in the cardiovascular system for different applications.
