you are trying to make a watchlist study , right?
so there is no chart, just 1 cell, like in excel, for displaying 1 variable value . 1.
plot and addlabel are outputs.
you have 3 plots and 1 label
which ONE of them has the data you want to see in the list?
change all 3 plots to def. replace the word plot with def.
disable the plot characteristic code lines by adding a # at the front of them ,
painting strategy, lineweight, color,...
these won't display in a watch list,
arrows, lines, bubbles, assert, assignpricecolor , ,....
your study has a lot of code lines that have no purpose in a watch list, so they should be removed, or disabled by adding a # at the front of the code lines.
you don't need to write out 'is true' if the variable is a true or false value ( 0 or 1). just use the variable itself as the condition.

#Alert(sslUp crosses below sslDown, "Trending Down", Alert.Bar, Sound.Ring);
#input colorbars = no;
#assignpricecolor(if colorbars and sslUP > ssldown then color.Green else if colorbars and ssldown > sslUP then color.Red else color.current);
#Addlabel(yes, if Upsigna is true then “ “ else if downsigna is true “ “ else “ “);
Addlabel(yes, “ “, color.blue);
#AssignBackgroundColor(if upsigna is true then color.green else if downsigna is true color.red else color.gray);
AssignBackgroundColor(if upsigna then color.green else if downsigna then color.red else color.gray);
#nit picking ,
you are using the word period instead of length , for the length of an average
