Hello,
I am hoping the community can help me understand a reliability issue I have observed with a multi-timeframe ProScreener I am developing.
The issue:
A stock (Deutsche Bank ADR, ticker PT on IG/ProRealTime) appeared in my scan results on Friday 20 June 2026 with a score of 11. On Monday 23 June 2026, it was completely absent from results — despite the monthly, weekly, and daily chart conditions appearing visually unchanged over the weekend.
My scan structure:
The scan uses three TIMEFRAME blocks — monthly, weekly, and daily — each computing their own MA, SMI, and MACD conditions. A mandatory filter (AND across all three timeframes) must pass before a TotalScore is computed. The stock is only returned if qualifies = Mandatory AND TotalScore >= 8.
What I have already ruled out:
- A new monthly candle opening (weekend was not month-end)
- A change in daily price direction (chart visually consistent)
- The score falling below threshold (score was 11 on Friday, well above threshold 8)
My specific questions:
- Can the TIMEFRAME() blocks in ProScreener behave differently between a Friday close session and a Monday open session — for example due to how the current incomplete bar is handled?
- Is there any known issue with multi-timeframe ProScreeners where a higher timeframe condition (e.g. monthly) can temporarily evaluate differently depending on when intraday the scan is run?
- Is there a recommended way to test or log which specific condition within a multi-timeframe scan is causing a stock to fail — for example, by temporarily outputting sub-scores or intermediate Boolean values?
I am running ProRealTime with an IT-Finance real-time data feed, scanning NASDAQ + NYSE universe.
