Using multiple timeframes in code

Hello Everybody,

Hope someone can help me. For a while i was having no trouble with a tradingsystem that run on multiple timeframes. On the four hour chart it watsches the historic volatility and on the 5 minutes charts i watch the trend . The system has worked perfectly, but suddenly i got the error that there was a division by zero.

I checked everything and pinpointed it to the coding i use to first check the 4 hour chart and use this as a condition in my 5 minute chart.

The coding without multiple timeframes was:

DEFPARAM CumulateOrders = False

DEFPARAM FLATBEFORE = 080000

DEFPARAM FLATAFTER = 220000

daysForbiddenEntry = OpenDayOfWeek = 6 OR OpenDayOfWeek = 0

ONCE Nbbarlimit = L

var1 = ExponentialAverage[20](close)>= ExponentialAverage[100](close)
var2 = High[0] < High[1]
var3 = Low[0] > Low[1]
var4 = ExponentialAverage[20](close)<= ExponentialAverage[100](close)
var5 = myhv >= B

indicator1 = CALL "Moving Average"[20, 1](close)


c1 = (indicator1 >= 8)
C2 = (indicator1 <= -8)

IF not onmarket and var1 AND var2 AND var3 and C1 then

When i add the coding for the multple timerframes it now gives the error “divison by 0”. Does anybody know what i am doing wrong?

DEFPARAM CumulateOrders = False

DEFPARAM FLATBEFORE = 080000

DEFPARAM FLATAFTER = 220000

daysForbiddenEntry = OpenDayOfWeek = 6 OR OpenDayOfWeek = 0

timeframe(4hour)
myhv = HistoricVolatility[20](close)

timeframe(5minute)
ONCE Nbbarlimit = L

var1 = ExponentialAverage[20](close)>= ExponentialAverage[100](close)
var2 = High[0] < High[1]
var3 = Low[0] > Low[1]
var4 = ExponentialAverage[20](close)<= ExponentialAverage[100](close)
var5 = myhv >= 0.12

indicator1 = CALL "Moving Average"[20, 1](close)


c1 = (indicator1 >= 8)
C2 = (indicator1 <= -8)

IF not onmarket and var1 AND var2 AND var3 and C1 then

kind regards,
