Hello sirâ€¦can you plz give tradescript code for this strategyâ€”btw its from tradingview.
study(â€śHullMAâ€ť,overlay=true)
n=input(title=â€śperiodâ€ť,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)

Dear Algo Thanks for info
This is giving error as requirement is as follow

When Candle breaches 13 EMA from below & then first candle it forms above 13 ema .

Now with coding given by you for every candle above 13 ema it is showing signal

Ako when i am giving a 5 MIN candle it is not showing signal at the end but in between signals are discpalyed
