Playback improvements: precise time range + manual bar-by-bar mode

Hi all,

while working extensively with Playback for strategy development and trade review, I noticed a relatively small improvements could significantly enhance usability and workflow.

  1. Precise Start time (and optional End time) + controlled loading

Currently, Playback only allows selecting a date, and data loading starts immediately after modifying an input field.

This creates a few issues:

  • No ability to define an exact intraday starting point (e.g. 09:30)
  • Frequent unintended reloads when adjusting inputs
  • Slower workflow when iterating over specific market situations
  • If you need to adjust multiple fields (e.g. start and end), data reload is triggered multiple times → you effectively have to wait twice

Even a minimal improvement would already help a lot:

  • Allow selection of a Start Time in addition to the date
  • Add a dedicated “Load” button to trigger data loading only after all inputs are configured
  • Prevent automatic reload on every single field change
