The interpretation of the BuySellArrows that can be added in
./graphic.pl as display elements is not quite correct.
The doc states that this "adds buy and sell arrows in the main chart,
based on systems signals". However, the signals generated by a system
are really just buy signals for long and short positions. The selling in
a system is performed by the close strategy. Only when the close
strategy is OppositeTrade is the second signal in fact a sell signal for
a buy entered due to the first signal in a system.
So the user needs to be careful not to be confused about this
difference. The sell signals will not be correct for a system with a
different close strategy.
Part of this confusion is due to the terminology in GT, where two
different things are called "system". The system object is really just a
combination of two signals (a long and a short signal). But then one
often refers to what is more properly a system manager as a system (a
combination of the former system with close strategy, trade filters,
brokers, money management, etc.).
