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
