The document examines an option whose payoff and premium are expressed in the underlying asset, using an ETH example to compare conversion from a conventional Black–Scholes value with a direct simulation. The key issue is the payoff definition: converting…
The document examines a reported average duration of roughly 25 minutes for continuous ETH price rises or falls, measured in five-minute intervals over three months. The response recommends defining what would count as unusual and comparing the observation…
The document explores exit choices for a crypto pairs trade entered after finding a cointegrated relationship. The trader reports that cointegration tests can stop indicating a relationship and later signal it again, while a simple exit at zero z-score has…
The document examines whether a Hurst exponent above 0.5 can justify shorting crypto futures after prices have fallen. The author estimates the exponent from 1,025 hourly mark-price observations for four Binance trading pairs and reports values around 0.62.…
The document questions whether standard GARCH models adequately describe one-minute Bitcoin returns. The sample is characterized by frequent zero returns, low return magnitudes, and apparent microstructure noise; the author also reports that squared…
The document addresses backtesting crypto strategies that calculate indicators on daily candles while processing finer-grained data for entries, exits, and risk controls. Its accepted answer recommends using Backtrader’s data replay feature with minute data…
The document responds to an observation that volatile Bitcoin prices seem to form a Weierstrass-like pattern across candlestick time scales. It explains that rough, fractal-like paths are not unique to cryptocurrency: Brownian motion and related stochastic…
The document raises a practical issue in a cryptocurrency perpetual-swap pair-trading strategy: a spread estimated by regression on log returns can produce opposite signals in consecutive observations. The author calculates the spread from rolling historical…
The discussion considers what market data to collect when building a Bitcoin price feeder for backtesting. Its practical recommendation is to begin with level-one data, such as trades and best bid and offer, and add order-book data only when a specific…
The document presents an interview scenario in which an exchange OTC desk must handle a corporate request to trade a very large quantity of bitcoin within a narrow band around the mid-market price. The requested size is several times the exchange’s stated…
The document lists a small set of quantitative trading competitions in response to a Singapore-based participant seeking opportunities beyond the International Quant Championship and SMU Alphathon. It mentions a stock-prediction model competition run by XTX…
The discussion considers how to allocate capital to an automated crypto strategy whose backtest suggests substantial drawdowns, and when to scale its exposure or stop trading as its edge may fade. The response emphasizes that changing position size is a…
This document raises a question about why a five-day exponential moving average can differ when calculated from hourly closes versus minute closes. The finer series contains more observations over the same calendar span, and the author reports seeing…
This document explains how to allocate a market-cap-weighted crypto index when no constituent may exceed a chosen maximum weight. It presents a sequential calculation: start with each asset’s share of total market value, scale that share by the weight and…
The document asks whether a long position in a quarterly bitcoin future and a short position in a perpetual swap can remain market neutral. It explains that perpetual swaps have no expiry and use funding payments to help keep their prices near spot. The…
The document raises practical questions about using XGBoost to predict whether the next candle’s closing price will move above or below a chosen threshold from the current open. The proposed feature set combines market sentiment, macroeconomic variables,…
The document explains how an exponential moving average can appear before a chart contains a full nominal lookback period. One answer describes a finite-window exponential weighting scheme: weights are normalized across the available observations, and the…
The document asks why a one-year Bitcoin futures contract can trade at a premium whose annualized rate exceeds a comparable government bond yield, despite standard cost-of-carry relationships. It considers whether demand for leveraged exposure may help…
The discussion asks whether Bitcoin has a quantifiable fair value and how mispricing might be recognized. The answers describe its traded price as an outcome of supply and demand once the market is sufficiently liquid, while emphasizing that speculation is…
The document asks whether reliable foreign-exchange prices are available during the weekend, when conventional spot markets are largely closed. The response cautions that quotes visible during quiet hours can be stale, making them poor evidence of current…
The discussion surveys proposed links between chaos theory, nonlinear dynamics, fractals, and financial markets. It points to research on nonlinear dynamics, self-similarity, the Hurst exponent, and the use of fractal ideas to model asset returns. One…
The document raises a modeling question about applying the heterogeneous autoregressive realized volatility model to forecast one-minute realized volatility in an active Bitcoin market. The proposed regressors are realized volatility measured over recent…
The document examines a hypothetical collapse in USDT’s value and considers its consequences for Bitcoin holders and market pricing. It distinguishes direct self-custody, exchange balances, and exposure through financial intermediaries. Self-custody does not…
The note explains how collateral and funding payments relate to liquidation in perpetual futures. In the answer’s account, a position is liquidated when collateral falls below the maintenance margin. Collateral includes the amount initially posted, realized…
