Information-Driven Bars represent a method of aggregating market data where price and volume bars are constructed based on specific quantities of market activity or information flow, rather than fixed time intervals. In crypto trading, these bars are instrumental in capturing genuine market movements and filtering out periods of inactivity, providing a more relevant representation of market dynamics.
Mechanism
These bars, such as tick bars, volume bars, or dollar bars, complete and form a new bar when a predetermined number of ticks, a specific trading volume, or a set dollar value of transactions is reached. This mechanism inherently normalizes the market signal by focusing on activity thresholds, effectively removing market noise during quiet periods and accentuating price changes during active trading.
Methodology
The strategic application of information-driven bars in smart trading algorithms and quantitative analysis within crypto markets aims to normalize the trading signal and enhance the predictive accuracy of models. By prioritizing market activity over arbitrary timeframes, this methodology reduces the serial correlation often present in time-based data, leading to more robust backtesting results and improved real-time decision-making for institutional investors and algorithmic strategies.
Information-driven bars improve volatility forecasts by synchronizing data sampling with market activity, yielding statistically cleaner inputs for models.
