binance api函数在尝试创建保证金贷款时崩溃

Question

我正在为api接口编写一个函数，用于在多头和空头保证金头寸之间快速切换。我的独立账户中有足够多的资金，以避免出现最小符号错误。创建订单后，债务和余额不会更新，当我调用switch（）函数时，程序会崩溃，因为程序要求从空帐户借款

当我尝试使用closeLong（）和closeShort（）偿还贷款时，也会留下一小笔余额，我无法解释原因，因为我使用的是从客户那里提取的确切债务金额。获取单独的保证金账户字典

编辑：这一对是OCEAN/USDT，是保证金的3倍，这就是为什么保证金基础和保证金报价的乘数是3

代码：

isLongOpen = False
acct = client.get_isolated_margin_account()
sym = acct['assets'][1]['symbol']
def getBaseBalance():
    rawBase = round(Decimal(acct['assets'][1]['baseAsset']['free']),2)
    baseBalance = str(rawBase)
    return baseBalance
def getMarginBase():
    rawBase = round(Decimal(acct['assets'][1]['baseAsset']['free']),2)
    marginBase=str(Decimal(3)* rawBase)
    return marginBase
def getQuoteBalance():
    rawQuote = round(Decimal(acct['assets'][1]['quoteAsset']['free']),2)
    baseQuote = str(rawQuote)
    return baseQuote
def getMarginQuote():
    rawQuote = round(Decimal(acct['assets'][1]['quoteAsset']['free']),2)
    marginQuote=str(Decimal(3)* rawQuote)
    return marginQuote

def baseDebt():
    baseLoan = round(Decimal(acct['assets'][1]['baseAsset']['borrowed']),2)
    print("Ocean Debt: "+str(baseLoan))
    return baseLoan
def quoteDebt():
    quoteLoan = round(Decimal(acct['assets'][1]['quoteAsset']['borrowed']),2)
    print("USDT Debt: "+str(quoteLoan))
    return quoteLoan

def checkDebt():
    if baseDebt()!=0:
        print("Short Open")
        isLongOpen = False
        return isLongOpen
    elif quoteDebt()!=0:
        print("Long Open")
        isLongOpen = True
        return isLongOpen

def openLong():
    client.create_margin_order(
        symbol=sym, 
        side= SIDE_BUY, 
        type= ORDER_TYPE_MARKET , 
        sideEffectType= 'MARGIN_BUY', 
        isIsolated='TRUE', 
        quoteOrderQty=getMarginQuote())
    print("Opened Long")

def closeLong():
    client.create_margin_order(
        symbol=sym,
        side=SIDE_SELL,
        type=ORDER_TYPE_MARKET,
        sideEffectType= 'AUTO_REPAY', 
        isIsolated='TRUE',
        quoteOrderQty=quoteDebt())  
    print("Closed Long")

def openShort():
    client.create_margin_order(
        symbol=sym,
        side=SIDE_SELL,
        type=ORDER_TYPE_MARKET,
        sideEffectType= 'MARGIN_BUY', 
        isIsolated='TRUE',
        quantity=getMarginBase())   
    print("Opened Short")

def closeShort():
    client.create_margin_order(
        symbol=sym,
        side=SIDE_BUY,
        type=ORDER_TYPE_MARKET,
        sideEffectType= 'AUTO_REPAY', 
        isIsolated='TRUE',
        quantity=baseDebt())  
    print("Closed Short")

def switch():
    if(checkDebt() == True):
        closeLong()
        print("Base " +getBaseBalance())
        print("Quote "+getQuoteBalance())
        openShort()
        print("Base " +getBaseBalance())
        print("Quote "+getQuoteBalance())
    else:
        closeShort()
        print("Base " +getBaseBalance())
        print("Quote "+getQuoteBalance())
        openLong()
        print("Base " +getBaseBalance())
        print("Quote "+getQuoteBalance())
    
    return isLongOpen
print(sym)
print("Base " +getBaseBalance())
print("Quote "+getQuoteBalance())
print(checkDebt())
print(switch())
print("Base " +getBaseBalance())
print("Quote "+getQuoteBalance())
print("END")

这是此代码的输出，用于从短路切换和从多头切换：
