The usage is very easy. When the line is green you can open long position, when the line is red you can open short position and when it's black just check by yourself.
Usually I use it with RSI and Bollinger Bands, in order to determine when the signal is strong or weak.

Just play with fastest and slowest SC to adjust the smoothness.
```//@version=2
study("Golden Cross Kaufman's Adaptive Moving Average",shorttitle="GC KAMA",overlay=true)
price=input(close)
len1=input(defval=12,minval=1,title="Fast")
len2=input(defval=26,minval=1,title="Slow")
fast=input(defval=2,minval=1,title="Fastest SC")
slow=input(defval=30,minval=1,title="Slowest SC")
fastestSC=(2/(fast+1))
slowestSC=(2/(slow+1))
change1=abs(price-price[len1])
diff1=abs(price-price[1])
volatility1=sum(diff1,len1)
ER1=change1/volatility1
SC1=pow(ER1*(fastestSC-slowestSC)+slowestSC,2)
out1=nz(out1[1])+SC1*(price-nz(out1[1]))
change2=abs(price-price[len2])
diff2=abs(price-price[1])
volatility2=sum(diff2,len2)
ER2=change2/volatility2
SC2=pow(ER2*(fastestSC-slowestSC)+slowestSC,2)
out2=nz(out2[1])+SC2*(price-nz(out2[1]))
plot(out1,color=out1>out2?(price>out1?green:black):(out1>price?red:black),title="GC KAMA",linewidth=2)```

Is there a way to receive an alert when the line changes from long to short and viceversa?

So you are saying a short position is now viable? Additional question, how come the chart does not show the recent hi of 49.25??
