- fix ES definition for the demo, thanks to Joseph Dunn for noticing
#!/usr/bin/Rscript --vanilla
#
# Rocema strategy, demonstrating among others:
# * using ternaryindicator that returns -1 (short), 0 (cash) or 1 (long)
# * using ordersets to handle simultaenous stop-loss and take-profit order, in
#   combination with market entry order and market exit order
# * using prefer='Open' on next bar
#
# tested with blotter svn r1057
