You can use a lot of AB code in several different ways. If the code contains
buy/sell statements, it will run in the backtester. If it contains
filter/addcolumn statements (as in this case), it will run in the explorer.
If it contains a "plot" statement, you can plot it as an indicator. You need
to add a plot statement - just do a search in the help files for further
info.
