Unable to use CALL…

  Hi guys, can you help me?
  I created this simple indicator, just to test the mechanisms of CALL functions in a trading system:

  EVSA

  once atrMonths = 3 once atrDays = round(5 * 4.1 * atrMonths) ema = average[Period,1] diff = ema -ema[1] ratio = diff / (averageTrueRange[atrDays]) signal = round(ratio) return signal as "Signal", 0 as "Central line"

  1 2 3 4 5 6 7 8

  once atrMonths = 3 once atrDays = round(5 * 4.1 * atrMonths) ema = average[Period,1] diff = ema -ema[1] ratio = diff / (averageTrueRange[atrDays])   signal = round(ratio) return signal as "Signal", 0 as "Central line"

  then I tried to use it in a dummy TS:

  a dummy TS

  signal, centralline = call "EVSA"[5] if not longOnMarket and signal and centralline = 0 then buy 1 contracts at market endif if longOnMarket and not signal then sell at market endif

  1 2 3 4 5 6 7 8 9

  signal, centralline = call "EVSA"[5]   if not longOnMarket and signal and centralline = 0 then buy 1 contracts at market endif   if longOnMarket and not signal then sell at market endif

  Unfortunately I receive this message (sorry it is in italian lang) saying that “EVSA” function should be called with an expression between parenthesis.
  

  I really don’t know how to fix this.
  Can you help me please?
  Regards
  R

  Add (CLOSE) at the end:

  signal, centralline = call "EVSA"[5](close)

  1	signal, centralline = call "EVSA"[5](close)
