v1.9.0 — Millisecond Bar Timing 2026-09-13

The bar-timing column now records milliseconds instead of whole seconds, timestamps can carry sub-second precision, VWAP resets at the true session open, and several export safeguards were tightened.

• Changed: The SecondsSincePrior column is now MsSincePrior, written as a decimal millisecond value with three decimal places. On price-based bar types — Renko, range and tick bars — several bars can complete inside the same second during fast markets, and whole-second timing truncated every one of those to zero. The column was renamed deliberately: earlier files carry whole seconds under the old header, so an import script can tell the two apart.
• Changed: The time format option HHmmss_WithPriorBar is now HHmmssfff_WithPriorBar and writes the bar time as HH:mm:ss.fff. Two bars closing in the same second no longer share an identical timestamp, which keeps the exported rows uniquely keyed for database loading.
• Sub-second resolution depends on your data feed. If the feed supplies only whole-second bar timestamps, MsSincePrior will hold multiples of 1000.
• Changed: Native VWAP now resets at the session open as defined by the chart's trading hours template, instead of at midnight. On RTH charts the output is identical to before. On ETH charts — where the session opens the previous evening — VWAP and PriorVWAP now reflect the full session rather than resetting mid-session at 12:00 AM.
• Fixed: If the FOMC/holiday date list failed to download, the export proceeded without the filter while the filename still carried the -noFH, -noFOMC or -noHol tag. The export is now blocked with a message in the Output window and the download is retried automatically; click Export again once it completes, or set Exclude dates to None.
• Changed: The save dialog now warns before overwriting an existing file. The prompt is skipped when either "Append timestamp to filename" or "Backup existing file before overwrite" is enabled, since neither can overwrite.
• Changed: Repeat exports from the same chart now suggest a freshly generated filename in the last-used folder, so the date range and filter tags stay current, instead of re-suggesting the previous full path.
