Forward Bar Function Starts Real-Time Tick Simulation Instead of Loading Completed Candle

Bug Reports

Description:
When attempting to move the chart forward by one candle/bar during replay or simulation mode, the platform does not generate the next completed bar as expected.

Instead, after pressing the “next bar” or forward function, the chart begins streaming real-time tick-by-tick price movement (live price simulation) inside the forming candle.

Expected Behavior:

  • Pressing the forward/next candle button should load the next fully completed bar/candle instantly.

  • The replay should continue candle-by-candle without switching into live tick simulation mode.

Actual Behavior:

  • Instead of displaying the next completed candle, the platform starts simulating live ticks in real time.

  • The next candle forms progressively tick-by-tick rather than appearing as a finished bar.

Impact:
This issue disrupts bar-by-bar backtesting and makes it difficult to analyze price action accurately using completed candles only.

How does this impact your experience?

    Hello @Sebastian Korzyniewski,

    Thank you for the detailed report, and sorry for the inconvenience this is causing.

    I tried to reproduce the issue on your latest project “KamaFX-nauka”, but I was not able to observe this behavior on my side.

    Could you please clarify a few details so we can investigate it properly?

    • the exact date and time when this happens

    • the timeframe you are using (M1, H1, etc.)

    • whether it happens on every symbol or only a specific one

    This information will help us narrow it down much faster.

    As a quick workaround meanwhile, you can try the following:

    • press Bar Backward several times first

    • then use Go to → Next Month Open

    This may help you bypass the problematic moment while we investigate the issue.

    We will continue looking into this carefully.
