# License: Mozilla Public License 2.0
# Migration notes:
#   offset= parameter not supported in @plot.line; default=0 so no visual difference
#   alertcondition() — no Indie equivalent
#   Both EMA and SMA series called unconditionally; selection via matype param
#   Dynamic fill and line colors computed per-bar
