  At this time, it just clears time trigger for the current instance. We will add the request for clearing by timer_id to the backlog. Other users please add a comment if you like the idea.

  I like it a lot, needless to say that cancelling specific timers adds a lot of flexibility

  I also like to have a end_time parameter when set up a time trigger. So, a trigger only lives during a time interval.

  current workaround to cancel a time trigger with specific id:

  `

  from cloudquant.interfaces import Strategy

  class test_trigger(Strategy):

  @classmethod
  def is_symbol_qualified(cls, symbol, md, service, account):
      return symbol == 'SPY'
  
  def on_start(self, md, order, service, account):
      service.add_time_trigger(service.time(9, 40),service.time_interval(0, 0, 1), timer_id='id-1')
      service.add_time_trigger(service.time(9, 40,10), timer_id='id-stop')
  
  def on_timer(self, event, md, order, service, account):
      if event.timer_id == 'id-1':
          print 'id-1', service.time_to_string(service.system_time)
  
      if event.timer_id=='id-stop':
          print 'id-stop', service.time_to_string(service.system_time)
          service.clear_time_triggers()
          service.add_time_trigger(service.time(9, 41), timer_id='id-2')
  
      if event.timer_id=='id-2':
          print 'this is id-2 trigger*****',self.symbol,service.time_to_string(service.system_time)
  
  
  def on_finish(self, md, order, service, account):
      pass
  

  `
  output :
  id-1 2016-12-13 09:40:00.000000
