Help Needed: Custom 2D/3D Screener in ProRealTime – Syntax Error

  Hi everyone,

  I’m trying to build a ProScreener in ProRealTime that scans for conditions on a custom time period, specifically 2-day (2D) or 3-day (3D) candles. However, I keep getting a syntax error when I try to use TIMEFRAME(2 days) or a similar approach.

  Error Screenshot Attached:
  The error message says:
  “Syntax error: line X, character XX
  One of the following characters would be more suitable than ‘2’:

  • ‘minute’, ‘hour’, ‘minutes’, or a timeframe hour (h, hour, hours)”

  Has anyone successfully created a screener or indicator using custom multi-day timeframes (other than 1 day, 1 week, etc.)?

  • Is this possible in the current version?

  • Are there any workarounds for scanning on 2D/3D periods?

  Any help or code examples would be much appreciated!

  Thanks in advance for your advice.

  Hi,
  These are the time frames (screenshot) you can use in a screener…

  A possible workaround is to aggregate the data manually…

  For a 2-day period, combine the last two daily bars as follows:
  Open of the 2-day bar = DOpen[1]
  High of the 2-day bar = max(DHigh, DHigh[1])
  Low of the 2-day bar = min(DLow, DLow[1])
  Close of the 2-day bar = DClose
