1.when i tried the oandatest and i set data0 as EUR_USD and my account and token , the error happened and this is the error.

File "oandatest.py", line 498, in <module>
    runstrategy()
  File "oandatest.py", line 310, in runstrategy
    cerebro.run(exactbars=args.exactbars)

    runstrat = self.runstrategies(iterstrat)

    strat._start()

    self.start()
  File "oandatest.py", line 180, in start
    if self.data0.contractdetails is not None:

    return getattr(self.lines, name)
AttributeError: 'Lines_LineSeries_DataSeries_OHLC_OHLCDateTime_Abst' object has no attribute 'contractdetails'

Is my input wrong ?
2. where can i put my strateygy in ? and what's the relation between data0 and data1?

You probably have a 2.0 account and the code is failing to receive the contractdetails from the server. You need a legacy account.

See Community - Oandatest no attribute 'contractdetails'

See the Docs - Quickstart or any of the hundreds of samples.

Using a live broker is just a matter of replacing the broker or store instances and there are specific documentations on how to do it.

For Oanda for example

and what's the relation between data0 and data1?.

Any relation between data0 and data1 is defined by you. Those are the data feeds you add to the system.
