Data Frequency

Data Frequency - The interval at which new data points arrive. High-frequency data (tick-level) provides every price change; lower-frequency data (e.g. 1-minute or 1-day bars) aggregates prices over fixed periods. Trading robots may use tick data for high-speed strategies or minute/daily bars for slower strategies. Frequency affects model resolution: tick data allows micro-second analysis, while historical bars are used for backtests or longer-term algorithms. Data frequency thus determines the granularity of input available to the robot.
