Add a Chart Bubble when 50SMA crosses below 100SMA


I would like to have have a bubble show on my chart when the 50MA crosses below the 100MA; the bubble text will be state "Short". Can anyone help me with this?
Adjust the inputs to your liking.

input price = close;
input fastLength = 20;
input slowLength = 50;
input averageType = AverageType.EXPONENTIAL;

plot FastMA = MovingAverage(averageType, price, fastLength);
plot SlowMA = MovingAverage(averageType, price, slowLength);

plot ArrowUp = if FastMA crosses above SlowMA
               then low
               else double.nan;
plot ArrowDN = if FastMA crosses below SlowMA
               then high
               else double.nan;
Alert(ArrowUp, " ", Alert.Bar, Sound.Chimes);
Alert(ArrowDN, " ", Alert.Bar, Sound.Bell);
def countUP = if FastMA crosses above SlowMA
              then 1
              else if FastMA > SlowMA
                   then countUP[1] + 1
              else if ArrowDN
                   then 0
                   else countUP[1];
AddLabel(1, "Count UP = " + countUP, color.white);
def CrossBar = if FastMA crosses SlowMa
               then barNumber()
               else double.nan;
AddChartBubble(barNumber() == HighestAll(CrossBar), FastMA, "Cross", color.cyan);

You said you wanted to be taught. So look where averagetype is used in the study. And change the averagtype for the plot you want to change. Looks like you wanted a 50 EMA cross of 75 SMA. So think how you would do that.
don't need help with that part exactly, I mean, like for example I just want to alert, when SMA(A) cross EMA(B).
like a message alert, so how do i go about it?... like can you guide me a bit?

@Buckbull You can setup a scanner and save it as a watchlist.


Here is the thinkScript code for the scanner:

close crosses SimpleMovingAvg("length" = 20)."SMA"

@Buckbull hang in there! This forum is the best forum I ever been apart of and I have been at this since TD Ameritrade brought/partnered with ThinkOrSwim. And I am just now learning the scripting (I have been wasting time doing other things in my life). BenTen provided you a great link.
