5.1 Introduction. For example: Step 1: The GPU memory can be automatically allocated and initialized by the CuPy array. 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). Ideally, the data scientists’ efforts should be focused on this step. The inference runs a forward pass from input to the output. Parameters of the Asian Barrier option. Fast Download Speed ~ Commercial & Ad Free. The latest version of the application can be downloaded at using the following link. The Monte Carlo simulation is an effective way to price them. An exotic option may also include non-standard underlying instrument, developed for a particular client or for a particular market. Non-constant coefficients require numerical methods for more general PDEs than those discussed in Chap. In general, it is performing a sequence of the following tasks: You must perform each step explicitly. ISBN 0-470-01684-1. 4.7 Conclusions. As you have no structural information about the six option parameters, choose the generic multiple layer perceptron neural network as the pricing model. pricing exotic options (Lasserre, Prieto-Rumeau and Zervos 2006). 5.2 Model and assumptions. The Asian Barrier Option is a mixture of the Asian Option and the Barrier Option. For each Monte Carlo simulation, you use 8.192 million paths to calculate the option price. This often makes it impossible to use closed-form equations to calculate their price. The seminar includes: Barrier Options, Asian Options, Look-Backs and Ratchet Options. In part 1 of this post, Python is used to implement the Monte Carlo simulation to price the exotic option efficiently in the GPU. An Asian option is a type of exotic option. 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. It works for any option pricing model that can be simulated using Monte Carlo methods. 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. Symmetries and Pricing of Exotic Options in Levy Models Ernst Eberlein and Antonis Papapantoleon. 6 Upwind schemes, stability issues and total variation diminishing are discussed.

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. 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 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. Deep neural networks can learn arbitrarily accurate functional approximations to the expected value derived by Monte Carlo techniques, and first order. Many exotic options are "path dependent", meaning their payoff depends not only on the final price of the underlying but also the behavior of the underlying throughout the time period. This is also shown in the Deeply Learning Derivatives paper: the prediction from the model is better than the result calculated from the Monte Carlo simulation with the same number of paths. It combines the benefits from both CUDA C/C++ and Python worlds. The following code example wraps the Barrier Option computation code inside the RawKernel object: Launching this GPU kernel in Python and running the Monte Carlo simulation takes 29 ms, which is very close to the benchmark of 26 ms for native CUDA code. 5. Inspired by it, you can convert the trained Asian Barrier Option model to the TensorRT inference engine to get significant acceleration. 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. 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. Exotic Option Pricing: Caplets and Floorlets Alexander Ockenden. The network architecture is shown in Figure 3. Here, you use eight million paths to show the computation advantage of GPU. Capital Markets Learning. 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. Public and Inhouse Courses. In the inner loop, the underlying asset price is updated step by step, and the terminal price is set to the resulting array. Hoboken, NJ: John Wiley & Sons. MG Soft Exotic Options Calculator; Pricing Asian option with arbitrary monitoring dates; Simultaneous Monte Carlo pricing of Asian and Barrier options; Download links. Launch the TensorRT engine to compute the result. Traditionally, Monte Carlo Option pricing is implemented in CUDA C/C++. 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. It made NVIDIA win the MLPerf Inference benchmark. It shows that the deep neural network can produce accurate pricing numbers and the inference time is orders of magnitude faster. 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. Call cuRand library to generate random numbers. The Black–Scholes model can efficiently be used for pricing “plain vanilla” options with the European exercise rule. The method that he introduced in this post does not pose any restrictions on the exotic option types. See our, Down-and-Out Call Discretized Asian Barrier Option, Fast Fractional Differencing on GPUs using Numba and RAPIDS (Part 1), Noise2Noise: Learning Image Restoration without Clean Data, How We Achieved Record Finance Benchmark Performance on Tesla K80, American Option Pricing with Monte Carlo Simulation in CUDA C++, Creating a Human Pose Estimation Application with NVIDIA DeepStream, Implementing Robotics Applications with ROS 2 and AI on the NVIDIA Jetson Platform. First, wrap all the computation inside a function to allow the allocated GPU memory to be released at the end of the function call. 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. Their technique is based on the work of Dawson which involves the use of moments to derive a solution for martingale problems. Asynchronously copy the output from device to host. Without loss of generality, you can use the Asian Barrier Option as an example. Figure 1 depicts the plan. In Part 1, I introduce Monte Carlo simulation implemented with Python GPU libraries. 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. 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. Call the std function to compute that the standard deviation of the pricing with 8 million paths is 0.0073. To simplify this article we will consider N equ… In total, 10 million training data points and 5 million validation data points are generated by running the Monte Carlo simulation in distribution. But if you have a deep learning pricing model, it is an easy task. Exotic Options Training Course. After the training is converged, the best performing model is saved in local storage. Exotic options: floating and fixed lookback option (FRM T3-45) - Duration: 13:45. Allocate GPU memory to store the random number and simulation path results. 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. Step 5: The deallocation of the GPU memory is automatically done by the Python memory management. This is our third post in the Exotic Option pricing using Monte Carlo Simulation series. This is because the noise in the Monte Carlo simulation is unbiased and can be cancelled out during the stochastic gradient training. Thus it is path-dependent as the price relies on knowing how the underlying behaved at certain points before expiry. ISBN 0-471-97958-9 Interest-rate Option Models: Understanding, Analysing and Using Models for Exotic Interest-rate Options. An Introduction To Exotic Option Pricing. This function returns the simulation result in a cudf GPU dataframe so that it can be aggregated into a dask_cudf distributed dataframe later. They can also be used in risk management to fit options prices at the portfolio level in view of performing some credit risk analysis. Learn more. By accelerating this computation in a V100 GPU, the computation time is reduced to 65 ms and produces the same result. Types of Exotic Options. The price of the option is the expected profit at the maturity discount to the current value. Exotic Option Pricing: Lookbacks and Asian Alexander Ockenden. 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. The differentiable neural network makes option Greeks calculation easy. Path-dependent options depend not only in the final price of the underlying instrument, but also on all the prices leading to the final price. In Part 2, I experiment with the deep learning derivative method. The RawKernel object allows you to call the kernel with CUDA’s cuLaunchKernel interface. Moving from CPU code to GPU code is easy with Numba. Furthermore, a simpler and more efficient lattice grid is introduced to implement the recursion more directly in matrix form. [5], "Why Do We Call Financial Instruments "Exotic"? DASK is an integrated component of RAPIDS for distributed computation on GPUs. Exotic Option Pricing and Advanced Levy Models. The source codes and example Jupyter notebooks for this post are hosted in the gQuant repo. In quantitative finance, low latency option pricing is important in the production environment to manage portfolio risk. When you have the TensorRT engine file ready, use it for inference work. For more information about the conversion, see the Jupyter notebook. You can use TensorRT to further improve the network inference time and achieve state-of-the-art performance. 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. The following code example is the detailed model implementation in PyTorch: In the gQuant GitHub repo, I provide two ways to train the neural network by using either Ignite or Neural Modules (NeMo). Using Python can produce succinct research codes, which improves research efficiency. Monte Carlo Pricing Book Description. For more information, see the Python notebooks in the GitHub repo. Then they are projected five times to the hidden dimension of 1024. The outer loop iterates through the independent paths. References. After training the deep learning network, the next step is usually to deploy the model to production. 4.6 Pricing of moment derivatives. I show it is easy to turn on the mixed precision training and multiple GPUs training to speed up the training. The single NVIDIA V100 GPU used earlier only has 16 GB of memory and you are almost hitting the memory limits to run 8M simulations. 3.1 General Features of Options 31 3.2 Call and Put Option Payoffs 32 3.3 Put–call Parity and Synthetic Options 34 3.4 Black–Scholes Model Assumptions 35 3.4.1 Risk-neutral Pricing 36 3.5 Pricing a European Call Option 37 3.6 Pricing a European Put Option 38 3.7 The Cost of Hedging 40 The final part of the chapter is devoted to penalty methods, here applied to a two-asset option. To get a more accurate estimation of the option price, you need more paths for the Monte Carlo simulation. Option pricing (exotic/vanilla derivatives) based on an efficient and general Fourier transform pricing framework - the PROJ method (short for Frame Projection). The following CUDA C/C++ code example calculates the option price by the Monte Carlo method: The CUDA code is usually long and detailed. 4.5 Pricing of exotic options. The path-dependent nature of the option makes an analytic solution of the option price impossible. Options like the Barrier option and Basket option have a complicated structure with no simple analytical solution. In finance, computation efficiency can be directly converted to trading profits sometimes. Use these numbers as the reference benchmark for later comparison. We walk through the minor tweaks required in our Monte Carlo Simulation model to price Asian, Lookback, Barrier & Chooser Options. MG Soft Exotic Options Calculator, version 1.0 beta (.msi) (release date April 7, 2009) It can be shown that a lot of running time can be saved. For the rest of the post, I focus on step 3, using Python to run a Monte Carlo simulation for the Asian Barrier Option. Exotic options are often created by financial engineers and rely on complex models to price them. Hello Select your address Best Sellers Today's Deals Electronics Customer Service Books New Releases Home Computers Gift Ideas Gift Cards Sell For the same number of simulation paths and steps, it takes 41.6s to produce the same pricing number. However, you can do much better. Touch‐and‐out Options. Inspired by this paper, I use a similar method in this post to build an approximated pricing model and speed up the inference latency. 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). 3 Vanilla Options 31. Get any books you like and read everywhere you want. Option Alpha 259,585 views. Abstract. I boost up the inference time further by transforming the model with TensorRT to provide state of art exotic option pricing speed. Like the more general exotic derivatives they may have several triggers relating to determination of payoff. 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. Exotic options are more complex than options that trade on an exchange, and are generally traded over the counter (OTC). Using GPU can speed up the computation by orders of magnitude due to the parallelization of the independent paths. Using a high-order differentiable activation function, I show that the approximated model can calculate option Greeks efficiently by network backward passes. There could be callability and putability rights. It works for any option pricing model that can be simulated using Monte Carlo methods.
