Subject : Help with making system out indicator.

I modified a stochastic momentum indicator by Mel Dickover by adding a signal line and using the original formula by Blau. Since I no experience with programming, I was amazed that it works just like the TOS platform indicator. I want to make a system that produces a long signal when the SMI line crosses above signal line and vice versa for the short signal. I also wanted to produce code to do the same in omniscan. Unfortunately, as this indicator is coded, I have no idea how to do this. I don't know how to access "SMI" to write a crossover with the EMA(3) of the SMI. Any nudges in the right direction would be greatly appreciated. Indicator code listed below:

#Indicator
'MySMI
'Stochastic Momentum Index indicator
'with signal line
'Based off initial indicator, SMI
' Coded by Mel Dickover April 2012
'------------------------------------------
#param "lookback", 5
#param "thresholdLong",-80
#param "thresholdShort",+80

dim temp1, temp2, temp3, temp4, temp5, temp6 as single
dim x as single
dim y as single

temp1 = (HHV(H,lookback)+LLV(L,lookback))*0.5 ' C
temp2 = C[0] - temp1 ' D
temp3 = EMA(temp2,3) 'DS1
temp4 = EMA(temp3,3) 'DS2
temp5 = EMA((HHV(H,lookback) - LLV(L,lookback)),3) 'DHL
temp6 = ema(temp5*0.5,3) 'DHL2
x = 100*(temp4/temp6)
y = EMA(x,3)

plot("SMI",x)
plot("Signal line",y)
plot("Thresholdlong",thresholdLong)
plotLabel(thresholdLong)
plot("Thresholdshort",thresholdShort)
plotLabel(thresholdshort)

Return x ' Return the value calculated by the indicator
Return y ' Return the value calculated by the signal line
