If prices move against 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, and in fast moving markets this 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 near to the expiry date compared to the price of the underlying instrument which does not occur on the CFD as it 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.
The industry practice is for the CFD provider to ' roll ' the CFD position to the next future period when the liquidity starts to dry in the last few days before expiry, thus creating a rolling CFD contract.
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. CFDs make it much easier to access global markets for much lower costs and much easier to move in and out of a position quickly.
All forms of margin trading involve financing costs, in effect the cost of borrowing the money for the whole position. Margin lending , also known as margin buying or leveraged equities , have all the same attributes as physical shares discussed earlier, but with the addition of leverage, which means like CFDs, futures, and options much less capital is required, but risks are increased.
The main benefits of CFD versus margin lending are that there are more underlying products, the margin rates are lower, and it is easy to go short. Even with the recent bans on short selling, CFD providers who have been able to hedge their book in other ways have allowed clients to continue to short sell those stocks.
Some financial commentators and regulators have expressed concern about the way that CFDs are marketed at new and inexperienced traders by the CFD providers.
In particular the way that the potential gains are advertised in a way that may not fully explain the risks involved. In computational modeling of turbulent flows, one common objective is to obtain a model that can predict quantities of interest, such as fluid velocity, for use in engineering designs of the system being modeled.
For turbulent flows, the range of length scales and complexity of phenomena involved in turbulence make most modeling approaches prohibitively expensive; the resolution required to resolve all scales involved in turbulence is beyond what is computationally possible.
The primary approach in such cases is to create numerical models to approximate unresolved phenomena. This section lists some commonly used computational models for turbulent flows.
Turbulence models can be classified based on computational expense, which corresponds to the range of scales that are modeled versus resolved the more turbulent scales that are resolved, the finer the resolution of the simulation, and therefore the higher the computational cost.
If a majority or all of the turbulent scales are not modeled, the computational cost is very low, but the tradeoff comes in the form of decreased accuracy.
In addition to the wide range of length and time scales and the associated computational cost, the governing equations of fluid dynamics contain a non-linear convection term and a non-linear and non-local pressure gradient term.
These nonlinear equations must be solved numerically with the appropriate boundary and initial conditions. An ensemble version of the governing equations is solved, which introduces new apparent stresses known as Reynolds stresses.
This adds a second order tensor of unknowns for which various models can provide different levels of closure.
It is a common misconception that the RANS equations do not apply to flows with a time-varying mean flow because these equations are 'time-averaged'.
In fact, statistically unsteady or non-stationary flows can equally be treated. There is nothing inherent in Reynolds averaging to preclude this, but the turbulence models used to close the equations are valid only as long as the time over which these changes in the mean occur is large compared to the time scales of the turbulent motion containing most of the energy.
Large eddy simulation LES is a technique in which the smallest scales of the flow are removed through a filtering operation, and their effect modeled using subgrid scale models.
This allows the largest and most important scales of the turbulence to be resolved, while greatly reducing the computational cost incurred by the smallest scales.
Regions near solid boundaries and where the turbulent length scale is less than the maximum grid dimension are assigned the RANS mode of solution.
As the turbulent length scale exceeds the grid dimension, the regions are solved using the LES mode. Therefore, the grid resolution for DES is not as demanding as pure LES, thereby considerably cutting down the cost of the computation.
Direct numerical simulation DNS resolves the entire range of turbulent length scales. This marginalizes the effect of models, but is extremely expensive.
The coherent vortex simulation approach decomposes the turbulent flow field into a coherent part, consisting of organized vortical motion, and the incoherent part, which is the random background flow.
The approach has much in common with LES, since it uses decomposition and resolves only the filtered portion, but different in that it does not use a linear, low-pass filter.
Instead, the filtering operation is based on wavelets, and the filter can be adapted as the flow field evolves. Goldstein and Vasilyev  applied the FDV model to large eddy simulation, but did not assume that the wavelet filter completely eliminated all coherent motions from the subfilter scales.
This approach is analogous to the kinetic theory of gases, in which the macroscopic properties of a gas are described by a large number of particles.
PDF methods are unique in that they can be applied in the framework of a number of different turbulence models; the main differences occur in the form of the PDF transport equation.
The PDF is commonly tracked by using Lagrangian particle methods; when combined with large eddy simulation, this leads to a Langevin equation for subfilter particle evolution.
The vortex method is a grid-free technique for the simulation of turbulent flows. It uses vortices as the computational elements, mimicking the physical structures in turbulence.
Vortex methods were developed as a grid-free methodology that would not be limited by the fundamental smoothing effects associated with grid-based methods.
To be practical, however, vortex methods require means for rapidly computing velocities from the vortex elements — in other words they require the solution to a particular form of the N-body problem in which the motion of N objects is tied to their mutual influences.
A breakthrough came in the late s with the development of the fast multipole method FMM , an algorithm by V.
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.
