before I start backtesting, may I hold some stock share?

As I can set cash at the begining, can I set a stock share like this?

cerebro.broker.set_position(size=10, price=100)

Yes, you can use order history for that.

# must be sorted ascending
# (datetime, size, prize, data)

ORDER_HISTORY = (('2012-04-11', 10, 100, 'AAPL'),)

cerebro = bt.Cerebro()
cerebro.adddata(data=bt.feeds.PandasData(dataname=aapl,),name='AAPL')
cerebro.add_order_history(ORDER_HISTORY)
cerebro.addstrategy(Strat)
cerebro.run()
