# 策略原理 策略基本思路是：买入低于X元的股票, 持有到1.25X元以上则卖出. ```py start = datetime(2014, 6, 1) end = datetime(2015, 3, 27) benchmark = 'HS300' # 策略参考标准 universe = set_universe('HS300') capital_base = 1000000 def initialize(account): account.buy_price_flag = 4 account.sell_price_flag = account.buy_price_flag*1.25 def handle_data(account): signals = [] acc_cash = account.cash for stock in account.universe: p = account.referencePrice[stock] if p < account.buy_price_flag: #满足买入条件，加入signals列表中 signals.append(stock) elif p >= account.sell_price_flag and account.secpos.get(stock, 0) > 0: #将卖出股票所得现金加入到本次的可用现金 acc_cash += account.referencePrice[stock]*account.secpos.get(stock,0) order_to(stock, 0) for stock in signals: # 平均买入signals列表中的股票 amount = acc_cash/len(signals)/account.referencePrice[stock] order(stock, amount) ```
