DESCRIPTION
Trading systems are systems that decide what to buy and sell at which prices and so on.
A system will propose buy/sell orders. The day after, those orders will be either cancelled or confirmed. If the order is confirmed, then a position is considered open. An open position will then be managed by a close strategy.
$system->long_signal($calc, $i)=item$system->short_signal($calc, $i)-
The system can generate 2 signals (buy or sell). A signal is an intent to buy or sell. Those functions should be overriden by the specific system.
$system->set_long_signal()$system->set_short_signal()-
Facility function to set which signal is used to generate buy/sell signal. They are meant to be used in initialize only if long_signal and short_signal are not overriden.
$system->precalculate_all($calc)=item$system->precalculate_interval($calc, $first, $last)-
If you run a system on a long period of time you may want to precalculate all the indicators in order to benefit of possible optimizations. This is the role of those 2 functions.
$system->default_order_factory()-
Return an object OrderFactory that can be used if no other objects was to be used.
