代码如下
klines = api.get_kline_serial(SYMBOL, duration_seconds=CYCLE, data_length=data_length)
target_pos = TargetPosTask(api, SYMBOL)
target_pos.set_target_volume(0)
account = api.get_account()
position = api.get_position(SYMBOL,account=TQACCOUNT)
order = api.get_order(SYMBOL,account=TQACCOUNT)
while True:
api.wait_update()
close = klines[“close”]
if api.is_changing(klines.iloc[-1], “datetime”):
KAMA = talib.KAMA(close, timeperiod = N)
klines[“KAMA_MAIN”] = KAMA
klines[“KAMA_MAIN.color”] = 0xFF000000
klines[“KAMA_MAIN.width”] = 3
if position.pos == 0 or order == “”:
# 均线下穿，做空
if KAMA.values[-1] < KAMA.values[-2]:
target_pos.set_target_volume(SELL)
print(“空头”)
# 均线上穿，做多
if KAMA.values[-1] > KAMA.values[-2]:
target_pos.set_target_volume(BUY)
print(“多头”)
