Returning information from a Screener

  Hi all,

  It seems the PRT screener can only ever return one variable for any instrument matching screening criteria.

  Are there plans to allow more than one to be returned ?

  If not, how many options are there for “overloading” the one value returned ?

  e.g an instrument matching a 15 minute “hit” on the screener with for example an RSI of 82 could be returned as 15,082 with some simple maths.

  Even direction can be added by using positive and negative numbers ( +15,082 and -15,082), however at that point are there more options ( use of colour / font / colour of the entry in the list ? )

  Is it possible to return text strings in any way ? ( ASCII encoding ? )

  Any ideas appreciated……..

  Only one criteria is possible for the list of results in ProScreener. I know that it should be extended in a next version, but I don’t know when.

  String variables are not possible and you can’t change the color of the criteria column.

  Another solution is to add ASCII symbol in the criteria description like I did in the attached screenshot.

  You can use a simple math. in your cas your RSI periods will need the rightmost 3 digits (0 -999), so you will have to multiply 15 by 1000 to make it use the two leftmost digits:

  TIMEFRAME(15 minute) MyRsi = Rsi[14](close) ReturnValue = 15000 + MyRsi SCREENER[MyRsi > 50](ReturnValue AS "My Criterion")

  1 2 3 4

  TIMEFRAME(15 minute) MyRsi = Rsi[14](close) ReturnValue = 15000 + MyRsi SCREENER[MyRsi > 50](ReturnValue AS "My Criterion")

  But this won’t help much if you use several TF’s. In this case I suggest that you use a pattern where the single digits refers to a single TF and, for each one of them, you could use 1 for positive data or 2 for negative data. Say you want to use 3 TF’s (4-hour, 1-hour and 15-minute TF’s), with 1=Macd > 0 and 2=Macd < 0, you could write:

  TIMEFRAME(4 hour) MyMacd4 = Macd[12,26,9] TIMEFRAME(1 hour) MyMacd1 = Macd[12,26,9] TIMEFRAME(15 minute) MyMacd15 = Macd[12,26,9] TIMEFRAME(default) IF MyMacd4 > 0 THEN Result4 = 100 ELSE Result4 = 200 ENDIF IF MyMacd1 > 0 THEN Result1 = 10 ELSE Result1 = 20 ENDIF IF MyMacd15 > 0 THEN Result15 = 1 ELSE Result15 = 2 ENDIF Result = Result4 + Result1 + Result15 SCREENER[Result](Result AS "415")

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

  TIMEFRAME(4 hour) MyMacd4 = Macd[12,26,9]   TIMEFRAME(1 hour) MyMacd1 = Macd[12,26,9]   TIMEFRAME(15 minute) MyMacd15 = Macd[12,26,9]   TIMEFRAME(default)   IF MyMacd4 > 0 THEN    Result4 = 100 ELSE    Result4 = 200 ENDIF   IF MyMacd1 > 0 THEN    Result1 = 10 ELSE    Result1 = 20 ENDIF   IF MyMacd15 > 0 THEN    Result15 = 1 ELSE    Result15 = 2 ENDIF   Result = Result4 + Result1 + Result15 SCREENER[Result](Result AS "415")

  the last line shows 415, where “4” refers to the 4-hour TF, “1” to the 1-hour TF and “5” to the 15-minute TF.

  As from attached pic, the first item in the list shows that AudUsd’s MACD is above 0 on the 4-h and 1-h TF’s, but below 0 on the 15-minute TF.
