Nowcasting bitcoin’s crash risk with order imbalance

چکیده
The spectacular nature of bitcoin price crashes baffles market spectators and prompts routine warnings from regulators cautioning that cryptocurrencies behave in contra to the fundamental properties traditionally define what constitutes money. Arguably most concerning public is, first, bitcoin’s unprecedented volatility relative other asset classes and, second, its seemingly detached behavior time-honored economic fundamentals. In an attempt create early warning system crash risk using generalized extreme value (GEV) logistic regression modeling, this study integrates order flow imbalance, along with several control factors which reflect blockchain activity network value, nowcast crashes. From a data analysis perspective, despite their dissimilar distributional underpinnings, GEV models perform comparably. When evaluating type I II errors these yield, it is shown performance comparable terms accuracy. addition, also how proportion can shift dramatically across probability cutoff tolerances. Towards end study, time varying probabilities are evaluated. sample range encompasses SARS-CoV-2 (Covid-19) period as well recent scandal collapse FTX cryptocurrency exchange.

Optimal Execution with Dynamic Order Flow Imbalance
We examine optimal execution models that take into account both market microstructure impact and informational costs. Informational footprint is related to order flow and is represented by the trader’s influence on the flow imbalance process, while microstructure influence is captured by instantaneous price impact. We propose a continuous-time stochastic control problem that balances between th...
متن کاملCertified Bitcoins
Bitcoin is a peer-to-peer (p2p) electronic cash system that uses a distributed timestamp service to record transactions in a public ledger (called the Blockchain). A critical component of Bitcoin’s success is the decentralized nature of its architecture, which does not require or even support the establishment of trusted authorities. Yet the absence of certification creates obstacles to its wid...
متن کاملCrash Risk Assessment with Cooperative Systems
Crash risk is the statistical probability of a crash. Its assessment can be performed through ex post statistical analysis or in real-time with on-vehicle systems. These systems can be cooperative. Cooperative Vehicle-Infrastructure Systems (CVIS) are a developing research avenue in the automotive industry worldwide. This paper provides a survey of existing CVIS systems and methods to assess cr...
متن کاملPredict the Stock price crash risk by using firefly algorithm and comparison with regression
Stock price crash risk is a phenomenon in which stock prices are subject to severe negative and sudden adjustments. So far, different approaches have been proposed to model and predict the stock price crash risk, which in most cases have been the main emphasis on the factors affecting it, and often traditional methods have been used for prediction. On the other hand, using Meta Heuristic Alg...
متن کاملNowcasting with Numerous Candidate Predictors
The goal of nowcasting, or “predicting the present,” is to estimate up-to-date values for a time series whose actual observations are available only with a delay. Methods for this task leverage observations of correlated time series to estimate values of the target series. This paper introduces a nowcasting technique called FDR (false discovery reduction) that combines tractable variable select...
