I set bt.TimeFrame.Days, with interactive brokers, but getting ticks?

rami

Next called every tick, and
inside
self.dnames['GOLDLONGD'].close[0] is real time value, but self.dnames['GOLDLONGD'].close[-1] previus tick, not Yestarday as i expect.

    def next(self):
        print("NEXT ") 
        print("{}".format(self.data.datetime.datetime(0).isoformat()))
        print("MKT(len={}) [0]{} [-1]{}".format(len(self.dnames['MKTD']),
                 self.dnames['MKTD'].close[0],
                 self.dnames['MKTD'].close[-1]))

     spygd = store.getdata(dataname='SPYG-STK-ARCA-USD',timeframe=bt.TimeFrame.Days)
     tltd = store.getdata(dataname='TLT-STK-ARCA-USD',timeframe=bt.TimeFrame.Days)
    gldd = store.getdata(dataname='IAU-STK-ARCA-USD',timeframe=bt.TimeFrame.Days)
    cerebro.addcalendar("NYSE")
    cerebro.adddata(spygd, name='MKTD')
    cerebro.adddata(tltd, name='BONDLONGD')
    cerebro.adddata(gldd, name='GOLDLONGD')

It's started ok, but later become very strange - i marked it BOLD

@backtrader thank you for reference, i took your referenced sample, and alter to make my own code.
i replaced resampledata to cerebro.adddata i use Days instead of ticks.
when i use resampledata - cerebro crashed, i open issue, but found by adddata it's run stable (without crashes)

Could you please point me what i doing wrong??

rami

@backtrader could you please advice why resampledata not working stable with IB ?

backtrader

That's a huge statement. You faced a problem, which doesn't mean it doesn't work in a stable manner.

In any case, there is not much advice I can offer, except for things like decreasing the number of symbols you request from IB simultaneously (that seems to work like a charm for everyone who doesn't know about the limitations placed by IB)
