Pine Repaint Check: Realtime Signal vs Bar Close

Record a developing signal during a live TradingView bar, then compare it with the confirmed close without pretending historical candles contain the missing ticks.

The checklist

  1. 1

    Name the exact signal

    Freeze the editable source, inputs, symbol and timeframe. The free example observes only its own EMA-cross signal and cannot inspect an invite-only indicator.

  2. 2

    Separate live and historical bars

    Pine indicators execute on live updates. A historical bar contains its final OHLC, not the sequence of values seen before close.

  3. 3

    Store the intrabar observation

    Use Pine varip state for a signal that becomes true on an open realtime bar. Reset that state at the start of the next bar.

  4. 4

    Compare at close

    Only the closing update determines whether the observed signal survived. Mark a disappeared signal on that closed bar, rather than moving a historical marker later.

  5. 5

    Keep a no-signal control

    A live bar with no signal should emit no marker and must not add to the discrepancy count.

  6. 6

    Check a close-only signal

    A signal that is present at the confirmed close is a different outcome from one that appeared and vanished intrabar.

  7. 7

    Document the reload boundary

    A reload, input change or new script instance loses prior intrabar observations. Do not treat the reloaded chart as a full replay of the live run.

  8. 8

    Separate other causes

    Higher-timeframe requests, alert snapshots, revised data and a third-party script need their own source and acceptance evidence.

Common questions

Did the public screenshot show a disappearing signal?

No. The genuine 2026-09-24 BTCUSDT one-minute chart snapshot showed the Pine indicator running live with 12 updates on one bar and zero lost or confirmed signals since load. It is execution evidence, not proof that the discrepancy branch fired.

Can this diagnose a protected indicator?

No. It sees only the signal defined in its own editable source. Diagnosing another indicator requires its authorized source and a frozen signal definition.

Can a screenshot of a reloaded chart prove the intrabar sequence?

No. Historical candles omit intrabar updates. Capture the live screen and bar-close state during the actual observation window.

Trading risk disclosure

Futures and forex trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing one's financial security or lifestyle. Only risk capital should be used for trading, and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

Hypothetical performance disclosure

Hypothetical performance results have many inherent limitations. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown. There are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. Hypothetical results are generally prepared with the benefit of hindsight, do not involve financial risk, and cannot completely account for the impact of financial risk in actual trading. Market conditions, the ability to withstand losses, and adherence to a trading program can all materially affect actual results.
