Calling an indicator from a system

  Is it possible too write an indicator with different timeframes and then call “Long” from a system? Cant get this too work out as I want.

  Indicator for long position

  // ============================= Variabler för olika tidsintervall TIMEFRAME(1 hours,updateonclose) ma1 = average[20](close) c11 = ma1 > ma1[1] // Lång position TIMEFRAME(30 minutes,updateonclose) ma304 = Average[4](typicalPrice) ma308 = Average[8](typicalPrice) c301 = ma304 > ma308 // Lång position TIMEFRAME(15 minutes,updateonclose) indicator2 = Average[4](typicalPrice) indicator3 = Average[8](typicalPrice) c151 = (indicator2 > indicator3) // Lång position TIMEFRAME(10 minutes,updateonclose) indicator4 = SuperTrend[1.4,6] c101 = close > indicator4 // Lång position TIMEFRAME(5 minutes,updateonclose) ma5 = average[20](typicalPrice) c51 = ma5 > ma5[1] // Lång position IF c11 AND c301 AND c151 AND c101 AND c51 THEN LONG = 1 ENDIF return LONG AS "LONG"

  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

  // ============================= Variabler för olika tidsintervall TIMEFRAME(1 hours,updateonclose) ma1 = average[20](close) c11 = ma1 > ma1[1] // Lång position   TIMEFRAME(30 minutes,updateonclose) ma304 = Average[4](typicalPrice) ma308 = Average[8](typicalPrice) c301 = ma304 > ma308 // Lång position   TIMEFRAME(15 minutes,updateonclose) indicator2 = Average[4](typicalPrice) indicator3 = Average[8](typicalPrice) c151 = (indicator2 > indicator3) // Lång position   TIMEFRAME(10 minutes,updateonclose) indicator4 = SuperTrend[1.4,6] c101 = close > indicator4  // Lång position   TIMEFRAME(5 minutes,updateonclose) ma5 = average[20](typicalPrice) c51 = ma5 > ma5[1] // Lång position   IF c11 AND c301 AND c151 AND c101 AND c51 THEN LONG = 1                                   ENDIF   return LONG AS "LONG"

  Yes. Use the CALL instruction in your strategy.

  https://www.prorealcode.com/documentation/call/

  However it is normally easier and more efficient just to hard code the indicator into your strategy.

  Also remember that you will need to run the strategy in a time frame that is compatible with the fastest time frame used in your indicator.

  Note: I gave your topic a more meaningful title – please try to use more descriptive titles with future topics.

  Just checking so I understand you right. The code is OK and all I need to is to call the indicator in the system.

  Yes.

  Personally I would just cut and paste the code (removing the RETURN line) into a strategy and then replace LONG = 1 on line 25 with BUY 1 CONTRACT AT MARKET thus avoiding using the CALL instruction entirely.

  I get “pro backtest.error.parsing” sometimes when I try too run a system calling an indicator. What is wrong when that happens?

  Even if I make a simple system as this ProRealTime give me a probacktest.error.parsing. Is it just me that have that problem?

  I contacted ProRealTime but they don’t answer me… is this a known problem or am I doing something wrong?

   

  suck Indicatore

  c11 = close crosses over average[20] return c11 AS "c11"

  1 2	c11 = close crosses over average[20] return c11 AS "c11"

  suck_system

  DEFPARAM CumulateOrders = false c11 = CALL "suck" IF c11 THEN BUY 1 Contract AT Market ENDIF

  1 2 3 4 5

  DEFPARAM CumulateOrders = false c11 = CALL "suck" IF c11 THEN BUY 1 Contract AT Market ENDIF

  I just tested your code and it worked fine on my platform on the DJI daily chart.

  I get parsing error sometimes when I run a indicator to a system. What is a parsing error?

  There was a discussion in the French forum last October about similar issues.

  https://www.prorealcode.com/topic/probacktest-error-parsing/

  The best work around is to avoid using CALL and hard code the indicator in your strategy for the time being.

  But if I want to sell a system and want too hide the code doesn’t I have too put in a indicator and call it from a system or is there any other way too do it?

  Yes that is the best way to do it. We may have to wait for PRT to investigate and fix this ‘parsing’ error before being able to code in this way though.

  Out of interest I just tested your simple test code on the DAX 5m and it worked just fine for me.

  I still have the error but thanx for the help for now. It is a little bit annoying when this appears but i guess it is just too wait out any solutions…
