Hull MA

Remove from Favorite Scripts Add to Favorite Scripts
study("HullMA",overlay=true)
n=input(title="period",type=integer,defval=16)


n2ma=2*wma(close,round(n/2))
nma=wma(close,n)
diff=n2ma-nma
sqn=round(sqrt(n))


n2ma1=2*wma(close[1],round(n/2))
nma1=wma(close[1],n)
diff1=n2ma1-nma1
sqn1=round(sqrt(n))


n1=wma(diff,sqn)
n2=wma(diff1,sqn)
c=n1>n2?green:red
ma=plot(n1,color=c)


Any ideas on how to create a global state so that you can save the colour of the previous iteration and compare it to the new iteration. That way you would be able to create an alert for when the Hull MA changes from red to green and vice versa.

Also similar alert ideas are welcome I just want to be alerted when the Hull MA changes colour.

Thanks
