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")

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")

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.
