Converting One-Minute Bars into Standard Timeframes and Rebuilding Volume

Summary

This document explains a chart utility that derives standard timeframe charts from one-minute data and can optionally recreate the one-minute volume series before conversion. A configurable parameter controls the treatment: negative values below a threshold leave the original minute bars unchanged, one setting recalculates volume only for bars whose original volume is one, another recalculates every bar from its price structure, and positive values assign a fixed user-specified volume to each bar.

For recalculation, the described rule counts distinct open, close, high, and low prices, with a caveat that the close must differ from both the high and low in the example rule. The note is implementation guidance for constructing chart history, not a trading strategy or evidence about market behavior. Recreated volumes are synthetic and can affect interpretation of indicators or backtests that depend on volume. It also says the trading terminal must be restarted for recreated quotes to appear in its history display.

Key ideas

• The utility aggregates one-minute chart data into standard timeframes.
• A parameter selects whether minute-bar volumes remain intact, are recalculated, or are replaced by a fixed value.
• One recalculation method derives volume from the distinct prices within a bar.
• Recreated volume is synthetic and should not be mistaken for observed trading activity.
• A terminal restart may be needed for the modified history to appear.
