exotic option pricing

Exotic options are often created by financial engineers and rely on complex models to price them. 5.5 Exotic options. Here, you use eight million paths to show the computation advantage of GPU. In finance, computation efficiency can be directly converted to trading profits sometimes. The RawKernel object allows you to call the kernel with CUDA’s cuLaunchKernel interface. This example code runs gen_data 100 times with different seed numbers and distributes the computation in the multiple-GPU environment. In part 1 of this post, Python is used to implement the Monte Carlo simulation to price the exotic option efficiently in the GPU. Learn more. For example: Step 1: The GPU memory can be automatically allocated and initialized by the CuPy array. They called this exotic option, the Asian option, because they were in Asia.[3]. An Introduction to Exotic Option Pricing [Buchen, Peter] on Amazon.com.au. The difference from the Deeply Learning Derivatives paper is using Elu as the activation function, to compute the high order differentiation of the parameters. But if you have a deep learning pricing model, it is an easy task. An exotic option may also include non-standard underlying instrument, developed for a particular client or for a particular market. In quantitative finance, low latency option pricing is important in the production environment to manage portfolio risk. I want to thank the NVIDIA Financial Service Industry team members Patrick Hogan, John Ashley, Alex Volkov, David Willians, Preet Gandhi and Mark Bennett. Asynchronously copy the output from device to host. By using RAPIDS/Dask, the large-scale Monte Carlo simulation can be easily distributed across multiple nodes and multiple GPUs to achieve higher accuracy. Exotic option pricing. In part 1 of this post, Python is used to implement the Monte Carlo simulation to price the exotic option efficiently in the GPU. However, after you have the neural network approximation model,  take advantage of the auto-grad feature in PyTorch to compute the differentiation. The Deeply Learning Derivatives paper proposed using a deep neural network to approximate the option pricing model, and using the data generated from the Monte Carlo simulation to train it. FX Exotic Options course. You can use any of the Python GPU Monte Carlo simulation methods described in part 1. Finance professionals who work on the development of new types of securities are called financial engineers. The path-dependent nature of the option makes an analytic solution of the option price impossible. The function takes an extra argument for the random number seed value so that the individual function calls each have an independent sequence of random numbers. Part 2: Option pricing by the deep derivative method. Calculating the Greeks with the Monte Carlo simulation method is challenging, due to the noise in price evaluation. In the following sections, see the Monte Carlo simulation in traditional CUDA code and then the same algorithm implemented in Python with different libraries. 3 Vanilla Options 31. In the Fast Fractional Differencing on GPUs using Numba and RAPIDS (Part 1) post, we discussed how to use the Numba library to accelerate Python code with GPU computing. In part 1, I showed you that the traditional way of implementing the Monte Carlo Option pricing in CUDA C/C++ is a little complicated, but that it has the best absolute performance. As shown in part 1, 8.192 million paths have the standard deviation of 0.0073 in the price of that particular option parameter set. As shown earlier, it runs quickly to get accurate results in 0.8 ms. An exotic option could have one or more of the following features: Even products traded actively in the market can have the characteristics of exotic options, such as convertible bonds, whose valuation can depend on the price and volatility of the underlying equity, the credit rating, the level and volatility of interest rates, and the correlations between these factors. Deep neural networks usually have good generalization, which is powerful for unseen datasets when the networks are trained with large amounts of data. Exotic options provide a great way for traders to take advantage of different trading dynamics that traditional options can’t address. Unlike a vanilla European option where the price of the option is dependent upon the price of the underlying asset at expiry, an Asian option pay-off is a function of multiple points up to and including the price at expiry. *FREE* shipping on eligible orders. The Black–Scholes model can efficiently be used for pricing “plain vanilla” options with the European exercise rule. Launch the sum kernel to aggregate the terminal underlying asset prices. Inspired by it, you can convert the trained Asian Barrier Option model to the TensorRT inference engine to get significant acceleration. Moving from CPU code to GPU code is easy with Numba. It can speed up the option price by a factor of 35x with accurate results. Allocate GPU memory to store the random number and simulation path results. Using a high-order differentiable activation function, I show that the approximated model can calculate option Greeks efficiently by network backward passes. The inference runs a forward pass from input to the output. By trading off compute time for training with inference time for pricing, it achieves additional order-of-magnitude speedups for options pricing compared to the Monte Carlo simulation on GPUs, which makes live exotic option pricing in production a realistic goal. This often makes it impossible to use closed-form equations to calculate their price. One-touch double barrier binary options are path-dependent options in which the existence and payment of the options depend on the movement of the underlying price through their option life. [4] Launch the barrier option kernel to do parallel simulations. The following code example computes the second order differentiation: You can generate the delta and gamma Greek graphs as a function of the underlying price: Implied volatility is the forecasted volatility of the underlying asset based on the quoted prices of the option. 4.5 Pricing of exotic options. Among the five steps, the critical component is step 3, where data scientists need to describe the detailed Monte Carlo simulation. In this post, TensorRT helps to accelerate the BERT natural language understanding inference to 2.2 ms on the T4 GPU. There could be callability and putability rights. For the same number of simulation paths and steps, it takes 41.6s to produce the same pricing number. Written by an experienced trader and consultant, Frans de Weert’s Exotic Options Trading offers a risk-focused approach to the pricing of exotic options. Exotic Option Pricing: Lookbacks and Asian Alexander Ockenden. Range of each of the parameters of the Asian Barrier option in dataset generation. It could involve foreign exchange rates in various ways, such as a, This page was last edited on 15 July 2020, at 14:43. Options like the Barrier option and Basket option have a complicated structure with no simple analytical solution. In general, it is performing a sequence of the following tasks: You must perform each step explicitly. The most straightforward way is to put the PyTorch model in inference mode. Launch the TensorRT engine to compute the result. Now you can load the model parameters and use it to run inference: When you feed in the same option parameters as in part 1, which is not used in the training dataset, the model produces the accurate option price $18.714. Call cuRand library to generate random numbers. The path results array can be defined by the following code example: Step 2: The CuPy random function uses the cuRAND library under the hood. References. You generate random option parameters (X independent variables), feed them to the Monte Carlo simulation in GPU and calculate the ground truth option prices (Y dependent variables).

Browse other questions tagged options option-pricing exotics or ask your own question. First, wrap all the computation inside a function to allow the allocated GPU memory to be released at the end of the function call. The following CUDA C/C++ code example calculates the option price by the Monte Carlo method: The CUDA code is usually long and detailed. Exotic option pricing and advanced Levy models By Andreas Kyprianou, Wim Schoutens, Paul Wilmott 2005 | 344 Pages | ISBN: 0470016841 | PDF | 4 MB Since around the turn of the millennium there has been a general acceptance that one of the more practical improvements one may make in the light of Using Python can produce succinct research codes, which improves research efficiency. This is our third post in the Exotic Option pricing using Monte Carlo Simulation series. Use Dask to run 1600×8 million simulations in a DGX-1 with the following code example: This additional computing power produces a more accurate pricing result of 18.71. In part 1 of this post, I showed you that the distributed calculation can be done easily with Dask. In finance, this is used to compute Greeks in the option. Numba can be used to compile Python code to machine code running in CPU as well. This chapter is devoted to exotic options, which include multifactor options and Asian options. Call the std function to compute that the standard deviation of the pricing with 8 million paths is 0.0073. 5.3 General description of the method. Exotic Options Training Course. Option Pricing – Pricing Exotic Options using Monte Carlo simulators. Without loss of generality, you can use the Asian Barrier Option as an example. Use the Down-and-Out Call Discretized Asian Barrier Option as an example. We compute the transition density of jump-extended models using convolution integrals. When you have the TensorRT engine file ready, use it for inference work. You can take advantage of it to distribute the Monte Carlo simulation computation to multiple GPUs across multiple nodes. Exotic options: floating and fixed lookback option (FRM T3-45) - Duration: 13:45. Table 1. I boost up the inference time further by transforming the model with TensorRT to provide state of art exotic option pricing speed. This is because the noise in the Monte Carlo simulation is unbiased and can be cancelled out during the stochastic gradient training. Book Description.

To simplify this article we will consider N equ… They are working in the field with FSI customers and provided useful comments and suggestions for this post. Bionic Turtle 1,685 views. This is a good sample option for pricing using the Monte Carlo simulation. K is strike price, B is barrier price, S0 is spot price, sigma is percent volatility, mu is percent drift and r is the interest rate. The method that he introduced in this post does not pose any restrictions on the exotic option types. As-You-Like-It Option: A type of exotic option that allows the option holder to choose whether the option is a call or a put. In an easy-to-understand, nontechnical yet mathematically elegant manner, An Introduction to Exotic Option Pricing shows how to price exotic options, including complex ones, without performing complicated integrations or formally solving partial differential equations (PDEs). The allocation and random number generation can be defined by the following code example: Step 4: The GPU mean value computation is a built-in function in the CuPy library. However, the trade-off is that these options almost always trade over-the-counter, are less liquid than traditional options, and are significantly more complicated to value. Figure 1 depicts the plan. The latest version of the application can be downloaded at using the following link. We review some of the existing methods using neural networks for pricing market and model prices, present calibration, and introduce exotic option pricing. I enabled the fastmath compiler optimization to speed up the computation. A Monte Carlo simulation, even accelerated in the GPU, is sometimes not efficient enough. The derivative price depends on the average of underlying Asset Price S, the Strike Price K, and the Barrier Price B. For more information about the conversion, see the Jupyter notebook. Luckily, each of the simulation paths are independent and you can take advantage of the multiple-core NVIDIA GPU to accelerate the computation within a node or even expand it to multiple servers, if necessary. Exotic Options: Pricing Path-Dependent single Barrier Option contracts Abukar M Ali Mathematics and Statistics Department Birkbeck, University of London Using GPU can speed up the computation by orders of magnitude due to the parallelization of the independent paths. 4.6 Pricing of moment derivatives. In the example shown, the Monte Carlo simulation can be computed efficiently with close to raw CUDA performance, while the code is simple and easy to adopt. It is the reverse mapping of price to the option parameter given the model which is hard to do with the Monte Carlo simulation approach. Public and Inhouse Courses. There are two general types of exotic options: path-independent and path-dependent. They can also be used in risk management to fit options prices at the portfolio level in view of performing some credit risk analysis. This function returns the simulation result in a cudf GPU dataframe so that it can be aggregated into a dask_cudf distributed dataframe later. In this code example, it evaluates the price of the Asian Barrier Option specified in the following table. We walk through the minor tweaks required in our Monte Carlo Simulation model to price Asian, Lookback, Barrier & Chooser Options. Hoboken, NJ: John Wiley & Sons.
