Time Triggers Question

Dustin_Lang

Does service.clear_time_triggers( ) clear all time triggers for all symbols? I would like to clear time triggers for a particular symbol and/or a given TimerID but this doesn't seem to be an option?

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

Yeah I definitely would like to see this!

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
