Unable to use CALL…

Roberto S. · 2018-07-27T19:19:24+00:00

Hi guys, can you help me? I created this simple indicator, just to test the mechanisms of CALL functions in a trading system: 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: 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. [attachment file=76922] I really don’t know how to fix this. Can you help me please? Regards R

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