本来从交易规则里直接获取交易精度是很合理的做法，奈何币安经常不及时更新这部分，遂弃坑。
def init():
global symbols, min_value
# 获取交易规则
exchange.SetBase('https://dapi.binance.com')
rule = exchange.IO("api", "GET", "/dapi/v1/exchangeInfo", "", "")["symbols"]
Log(rule)
# 获取交易对名称
for i in range(len(exchanges)):
exchanges[i].SetMarginLevel(M)
exchanges[i].SetContractType("swap") # 设置永续合约
_symbol = exchanges[i].GetCurrency().split("_")[0] # +'USDT'币本位交易对名称
# 设置交易精度
j = 0
flag1 = False
flag2 = False
#Log(rule)
while (j < len(rule)) and flag1 == False and flag2 == False:
if str(rule[j]["symbol"]).rfind(_symbol)>=0:
for x in rule[j]["filters"]:
if x["filterType"] == "PRICE_FILTER" and flag1 == False:
#Log("价格",x["tickSize"])
#Log(len(str(float(x["tickSize"])).split('.')[-1]))
price_precision = len(str(float(x["tickSize"])).split('.')[-1])
flag1 = True
elif x["filterType"] == "LOT_SIZE" and flag2 == False:
amount_precision = len(x["minQty"].split('.')[-1])
flag2 = True
j = j + 1
exchanges[i].SetPrecision(price_precision, amount_precision)
Log("初始化结束")
