from tqsdk import TqApi, TqSim, tafunc
from tqsdk.ta import MACD
api = TqApi(TqSim())
klines = api.get_kline_serial(“DCE.i2009”, 24 * 60 * 60)
macd=MACD(klines,12,26,9)
mbar=macd[“bar”]
mbar_crossup_0 = tafunc.crossup(mbar,0)
api.close()
运行时总是出现错误提示：
crossdown_data = pd.Series(np.where((a < b) & (a.shift(1) >= b.shift(1)), 1, 0))
AttributeError: ‘int’ object has no attribute ‘shift’
Task was destroyed but it is pending!
应如何解决？

换成diff金叉dea，还是会出错：
from datetime import date, datetime
from tqsdk import TqApi, TqSim, TargetPosTask, TqAccount, tafunc, TqBacktest, TqReplay
from tqsdk.ta import MACD
api = TqApi(TqSim(),backtest=TqBacktest(start_dt=date(2020,5,1), end_dt=date(2020,6,12)),web_gui=”:1234″)
SYMBOL=”DCE.i2009″
klines = api.get_kline_serial(SYMBOL, 24 * 60 * 60)
quote = api.get_quote(SYMBOL)
macd=MACD(klines,12,26,9)
while True:
api.wait_update()
if api.is_changing(klines.iloc[-1], [“datetime”, “open”]):
macd=MACD(klines,12,26,9)
if api.is_changing(quote, “last_price”):
mdif=macd[“diff”]
mdea=macd[“dea”]
if tafunc.crossup(mdif,mdea) :
target_pos.set_target_volume(1)
api.close()
运行后出现错误提示。
