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. Exotic Options: Pricing Path-Dependent single Barrier Option contracts Abukar M Ali Mathematics and Statistics Department Birkbeck, University of London This chapter is devoted to exotic options, which include multifactor options and Asian options. I showed several benefits when using a neural network to approximate the exotic option price model. Numba can be used to compile Python code to machine code running in CPU as well. An Asian option is a type of exotic option. They are working in the field with FSI customers and provided useful comments and suggestions for this post. Exotic options are often created by financial engineers and rely on complex models to price them. An Introduction To Exotic Option Pricing. 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. Barriers in exotic option are determined by the underlying price and ability of the stock to be active or inactive during the trade period, for instance up-and –out option has a high chance of being inactive should the underlying price go beyond the marked barrier. 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. This is a 32x speedup. 4.5 Pricing of exotic options. The purpose of this workshop is understanding of pricing, risks and applications of exotic options. You can use TensorRT to further improve the network inference time and achieve state-of-the-art performance. [5], "Why Do We Call Financial Instruments "Exotic"? In the following sections, see the Monte Carlo simulation in traditional CUDA code and then the same algorithm implemented in Python with different libraries. Using Python GPU libraries, the exact same Monte Carlo simulation can be implemented in succinct lines of Python code without a significant performance penalty. The latest version of the application can be downloaded at using the following link. *FREE* shipping on eligible orders. One interesting finding from the Noise2Noise: Learning Image Restoration without Clean Data paper is that the model trained with noisy ground truth data can restore the clean prediction. 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. Quants are facing the challenges of trading off research efficiency with computation efficiency. The Perpetual Russian Option. Then they are projected five times to the hidden dimension of 1024. Up-and-in option is very likely to be active should the underlying price go beyond the marked barrier. Lookback and Barrier Options in a Lévy Market. To simplify this article we will consider N equ… Exotic Option Pricing and Advanced Levy Models. Recently, the Deeply Learning Derivatives (Ryan et al, 2018) paper was introduced to approximate the option pricing model using a deep neural network. 5.3 General description of the method. Hoboken, NJ: John Wiley & Sons. 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). CuPy provides an easy way to define GPU kernels from a raw CUDA source. This example code runs gen_data 100 times with different seed numbers and distributes the computation in the multiple-GPU environment. The approximated option pricing model is fully differentiable, which means that you can calculate any order of differentiation with respect to input parameters. In this Jupyter notebook, I show it is useful to do batch Monte Carlo simulation, which effectively uses many paths. MG Soft Exotic Options Calculator; Pricing Asian option with arbitrary monitoring dates; Simultaneous Monte Carlo pricing of Asian and Barrier options; Download links. 3 Vanilla Options 31. The method that he introduced in this post does not pose any restrictions on the exotic option types. Furthermore, a simpler and more efficient lattice grid is introduced to implement the recursion more directly in matrix form. In part 1 of this post, Python is used to implement the Monte Carlo simulation to price the exotic option efficiently in the GPU. For example: Step 1: The GPU memory can be automatically allocated and initialized by the CuPy array. Touch‐and‐out Options. This is because the noise in the Monte Carlo simulation is unbiased and can be cancelled out during the stochastic gradient training. DASK is an integrated component of RAPIDS for distributed computation on GPUs. 5.2 Model and assumptions. Using GPU can speed up the computation by orders of magnitude due to the parallelization of the independent paths. The RawKernel object allows you to call the kernel with CUDA’s cuLaunchKernel interface. 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. 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. They can also be used in risk management to fit options prices at the portfolio level in view of performing some credit risk analysis. Exotic Options Training Course. Monte Carlo Pricing Calculating the Greeks with the Monte Carlo simulation method is challenging, due to the noise in price evaluation. To enable computation across multiple CPU cores, you parallelize the outer for-loop by changing range to prange: This code produces the same pricing result but now takes 2.34s to compute it in the 32-core, hyperthreading DGX-1 Intel CPU. Finance professionals who work on the development of new types of securities are called financial engineers. 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. Down-and-in-option is very likely to be active should the underlying prices of the stock go below the marked barrier. pricing exotic options (Lasserre, Prieto-Rumeau and Zervos 2006). You can take advantage of it to distribute the Monte Carlo simulation computation to multiple GPUs across multiple nodes. NVIDIA websites use cookies to deliver and improve the website experience. Like the more general exotic derivatives they may have several triggers relating to determination of payoff. It works for any option pricing model that can be simulated using Monte Carlo methods. Their technique is based on the work of Dawson which involves the use of moments to derive a solution for martingale problems. It computes efficiently as the gradient is computed by the backward pass of the network. Here, you use Dask to generate a large dataset in a distributed manner: The gen_data function runs in a single GPU to generate a set of data points and save them in the local storage. In finance, this is used to compute Greeks in the option. However, after you have the neural network approximation model,  take advantage of the auto-grad feature in PyTorch to compute the differentiation. MG Soft Exotic Options Calculator, version 1.0 beta (.msi) (release date April 7, 2009) A deep neural network is known to be a good function approximator, which has a lot of success in image processing and natural language processing. He argued that just as the exotic wagers survived the media controversy so will the exotic options. The Black–Scholes model can efficiently be used for pricing “plain vanilla” options with the European exercise rule. Both are high-level DL libraries to make train models easy. As you know the range of the generated random option parameters, the input parameters are first scaled back to a range of (0-1) by dividing them by (200.0, 198.0, 200.0, 0.4, 0.2, 0.2). Option Pricing – Pricing Exotic Options using Monte Carlo simulators. The outer loop iterates through the independent paths. The following code example is an implementation of the Monte Carlo simulation optimized to run in a single core CPU: The Monte Carlo simulation has two nested for-loops. FX Exotic Options course. The Monte Carlo simulation is an effective way to price them. The differentiable neural network makes option Greeks calculation easy. A Monte Carlo simulation, even accelerated in the GPU, is sometimes not efficient enough. If you use ReLu as in the original paper, the second order differentiation is always zero. Additionally, after moving the simulation code to Python, you can use other helpful Python libraries to improve the outcome. This post is organized in two parts with all the code hosted in the gQuant repo on GitHub: The method that I introduced in this post does not pose any restrictions on the exotic option types. A lot of tricks can be used to reduce the number of paths needed for the simulation, for example, importance sampling technique. In finance, computation efficiency can be directly converted to trading profits sometimes. Read the full blog, Accelerating Python for Exotic Option Pricing, on the NVIDIA Developer Blog. Launch the TensorRT engine to compute the result. The source codes and example Jupyter notebooks for this post are hosted in the gQuant repo. Best of all, it only takes 0.8 ms to do the calculation compared with 26 ms done by the Monte Carlo method in CUDA. As shown earlier, it runs quickly to get accurate results in 0.8 ms. Call cuRand library to generate random numbers. 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. Use these numbers as the reference benchmark for later comparison. Options like the Barrier option and Basket option have a complicated structure with no simple analytical solution. I enabled the fastmath compiler optimization to speed up the computation. In total, 10 million training data points and 5 million validation data points are generated by running the Monte Carlo simulation in distribution. The numerical difference method can be noisy. Among the five steps, the critical component is step 3, where data scientists need to describe the detailed Monte Carlo simulation. The following code example runs inference with the TensorRT engine: It produces accurate results in a quarter of the inference time (0.2 ms) compared to the non-TensorRT approach.

The Asian Barrier Option is a mixture of the Asian Option and the Barrier Option. After training the deep learning network, the next step is usually to deploy the model to production. The following CUDA C/C++ code example calculates the option price by the Monte Carlo method: The CUDA code is usually long and detailed. 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. For the rest of the post, I focus on step 3, using Python to run a Monte Carlo simulation for the Asian Barrier Option. Abstract. Types of Exotic Options. The price of the option is the expected profit at the maturity discount to the current value. Exotic Option Pricing: Caplets and Floorlets Alexander Ockenden. Ask Question Asked 8 years, 2 months ago. Because the Monte Carlo simulation can be used to find the accurate price of the option, you can use it to generate as many data points as possible given the computation budgets. In quantitative finance, low latency option pricing is important in the production environment to manage portfolio risk. 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. The last layer is a linear layer that maps the hidden dimension to the predicted option price. An Introduction to Exotic Option Pricing [Buchen, Peter] on Amazon.com.au. 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. Asynchronously copy the input from host to device. In this post, I explore how to use Python GPU libraries to achieve the state-of-the-art performance in the domain of exotic option pricing. 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). After the training is converged, the best performing model is saved in local storage. Sample the six option parameters uniformly in the range specified in the following table: Table 2. Compiling and running this CUDA code on a V100 GPU produces the correct option price $18.70 in 26.6 ms for 8.192 million paths and 365 steps. The inference runs a forward pass from input to the output. 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. 4.7 Conclusions. Part 2: Option pricing by the deep derivative method. Active 8 years, 2 months ago. Hello Select your address Best Sellers Today's Deals Electronics Customer Service Books New Releases Home Computers Gift Ideas Gift Cards Sell Parameters of the Asian Barrier option. By giving readers the necessary tools to understand exotic options, this book serves as a manual to equip the reader with the skills to price and risk manage the most common and the most complex exotic options. We walk through the minor tweaks required in our Monte Carlo Simulation model to price Asian, Lookback, Barrier & Chooser Options. [1], In 1987, Bankers Trust Mark Standish and David Spaughton, were in Tokyo on business when "they developed the first commercially used pricing formula for options linked to the average price of crude oil." Ideally, the data scientists’ efforts should be focused on this step. Given the prices P, the implied volatility is the root of the function `compute_price` as in the following code example: Any numerical root-finding methods can be used, for example, the Brent algorithm is efficient to compute the root. A backward Monte Carlo approach to exotic option pricing† - Volume 29 Issue 1 - G. BORMETTI, G. CALLEGARO, G. LIVIERI, A. PALLAVICINI You can use any of the Python GPU Monte Carlo simulation methods described in part 1. Thus it is path-dependent as the price relies on knowing how the underlying behaved at certain points before expiry. The final part of the chapter is devoted to penalty methods, here applied to a two-asset option. Because some of them are from Japan", https://en.wikipedia.org/w/index.php?title=Exotic_option&oldid=967823028, Creative Commons Attribution-ShareAlike License, The payoff at maturity depends not just on the value of the underlying instrument at maturity, but at its value at several times during the contract's life (it could be an, It could depend on more than one index such as in, The manner of settlement may vary depending on the. Palmer compared these horse racing bets to the controversial emerging exotic financial instruments that concerned then-chairman of the Federal Reserve Paul Volcker in 1980. 5.5 Exotic options. The maturity for this option is fixed at one year for this study. This function returns the simulation result in a cudf GPU dataframe so that it can be aggregated into a dask_cudf distributed dataframe later. We compute the transition density of jump-extended models using convolution integrals. First, wrap all the computation inside a function to allow the allocated GPU memory to be released at the end of the function call. ISBN 0-470-01684-1. Learn more.

It can be shown that a lot of running time can be saved. Interest-rate Option Models: Understanding, Analysing and Using Models for Exotic Interest-rate Options. It combines the benefits from both CUDA C/C++ and Python worlds. In part 1 of this post, Python is used to implement the Monte Carlo simulation to price the exotic option efficiently in the GPU. A straight call or put option, either American or European, would be considered non-exotic or vanilla option. To get a more accurate estimation of the option price, you need more paths for the Monte Carlo simulation. Asynchronously copy the output from device to host. In finance, an exotic option is an option which has features making it more complex than commonly traded vanilla options. ResolutionExotics provides pricing for the folowing instruments, option pricing, exotic options, barrier options, double barrier options, digital options and look back options. Traditionally, the Monte Carlo simulation on GPUs is implemented in CUDA C/C++ code. Exotic Option Pricing: Lookbacks and Asian Alexander Ockenden.
