The model aims to capture and\u0000generalise transaction queueing infrastructure that has arisen to organise MEV\u0000activity on public blockchains such as Ethereum, providing convenient channels\u0000for sophisticated agents to extract value by acting on end-user order flow by\u0000performing arbitrage and related HFT activities. In our model, market orders\u0000are interspersed with orders created by arbitrageurs that under idealised\u0000conditions reset the marginal price to a global equilibrium between each trade,\u0000improving predictability of execution for liquidity traders. If an arbitrageur has a chance to land multiple opportunities in a row, he\u0000may attempt to manipulate the execution price of the intervening market order\u0000by a probabilistic blind sandwiching strategy. To study how bad this\u0000manipulation can get, we introduce and bound a price manipulation coefficient\u0000that measures the deviation from global equilibrium of local pricing quoted by\u0000a rational arbitrageur. We exhibit cases in which this coefficient is well\u0000approximated by a \"zeta value' with interpretable and empirically measurable\u0000parameters.","PeriodicalId":501478,"journal":{"name":"arXiv - QuantFin - Trading and Market Microstructure","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139482763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AMMs are typically implemented as smart contracts on\u0000blockchains, and its prices are kept in line with the overall market price by\u0000arbitrage: if the AMM undervalues an asset with respect to the market, an\u0000\"arbitrageur\" can make a risk-free profit by buying just enough of that asset\u0000to bring the AMM's price back in line with the market. AMMs, however, are not designed for assets that expire: that is, assets that\u0000cannot be produced or resold after a specified date. As assets approach\u0000expiration, arbitrage may not be able to reconcile supply and demand, and the\u0000liquidity providers that funded the AMM may have excessive exposure to risk due\u0000to rapid price variations. This paper formally describes the design of a decentralized exchange (DEX)\u0000for assets that expire, combining aspects of AMMs and limit-order books. We\u0000ensure liveness and market clearance, providing mechanisms for liquidity\u0000providers to control their exposure to risk and adjust prices dynamically in\u0000response to situations where arbitrage may fail.","PeriodicalId":501478,"journal":{"name":"arXiv - QuantFin - Trading and Market Microstructure","volume":"83 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139409635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strategies that the agent is allowed to deploy\u0000is subject to a benchmark, referred to as the reservation strategy, regulated\u0000by the client. We formulate the broker's problem as a utility maximization\u0000problem in which the broker seeks to maximize his utility of excess\u0000profit-and-loss at the execution horizon.

These measures of volatility serve as indicators of market\u0000expectations for conditional volatility and are compared to elucidate their\u0000differences and similarities. The central finding of this study underscores a\u0000notably high expected level of volatility, both on a daily and annual basis,\u0000across all the methodologies employed. However, it's crucial to emphasize the\u0000potential challenges stemming from suboptimal liquidity in the Bitcoin options\u0000market. These liquidity constraints may lead to discrepancies in the computed\u0000values of implied volatility, particularly in scenarios involving extreme\u0000moneyness or maturity.

The results\u0000obtained in the frame of this mathematical model show that starting from year\u00002014 the majority of the world countries would have preferred to trade in BRI\u0000than USD. The Monte Carlo process reaches a steady state with 3 distinct\u0000groups: two groups of countries preferring, whatever is the initial\u0000distribution of the trade currency preferences, to trade, one in BRI and the\u0000other in USD, and a third group of countries swinging as a whole between USD\u0000and BRI depending on the initial distribution of the trade currency\u0000preferences.

AI-driven models, particularly those employing\u0000ML techniques such as deep learning and reinforcement learning, have shown\u0000great prowess in predicting market trends and executing trades at a speed and\u0000accuracy that far surpass human capabilities. Its capacity to automate critical\u0000tasks, such as discerning market conditions and executing trading strategies,\u0000has been pivotal. However, persistent challenges exist in current QT methods,\u0000especially in effectively handling noisy and high-frequency financial data.\u0000Striking a balance between exploration and exploitation poses another challenge\u0000for AI-driven trading agents. To surmount these hurdles, our proposed solution,\u0000QTNet, introduces an adaptive trading model that autonomously formulates QT\u0000strategies through an intelligent trading agent. Incorporating deep\u0000reinforcement learning (DRL) with imitative learning methodologies, we bolster\u0000the proficiency of our model. To tackle the challenges posed by volatile\u0000financial datasets, we conceptualize the QT mechanism within the framework of a\u0000Partially Observable Markov Decision Process (POMDP). Moreover, by embedding\u0000imitative learning, the model can capitalize on traditional trading tactics,\u0000nurturing a balanced synergy between discovery and utilization. For a more\u0000realistic simulation, our trading agent undergoes training using\u0000minute-frequency data sourced from the live financial market.
