import time


def supply_bnb(transfer_usdt,i):
    Log("当前BNB不足，补充BNB作为手续费抵扣")
    #获取当前BNB_USDT价格
    depth = _C(exchanges[i].GetDepth)
    #转出transfer_usdt个USDT
    timestamp = time.time() * 1000
    transfer = exchanges[i].IO("api","POST","/sapi/v1/futures/transfer","asset=USDT&amount="+str(transfer_usdt)+"&type=2&timestamp=+"+str(timestamp))
    time.sleep(1)
    #获取BNB深度 下单购买
    depth = _C(exchanges[i].GetDepth)
    buyamount = round(transfer_usdt / (depth.Asks[0].Price + 0.2) , 2)
    buyid = exchanges[i].Buy(round(depth.Asks[0].Price + 0.1 , 4) , buyamount)
    time.sleep(1)
    #查询购买结果 将购买后的BNB以及剩余的USDT转入合约账户
    acc = _C(exchanges[i].GetAccount)
    transfer_usdt = acc.Balance
    transfer_bnb = acc.Stocks
    timestamp = time.time() * 1000
    transfer = exchanges[i].IO("api","POST","/sapi/v1/futures/transfer","asset=USDT&amount="+str(transfer_usdt)+"&type=1&timestamp=+"+str(timestamp))
    transfer = exchanges[i].IO("api","POST","/sapi/v1/futures/transfer","asset=BNB&amount="+str(transfer_bnb)+"&type=1&timestamp=+"+str(timestamp))
    Log("BNB补充完成")




def main():
    if '合约账户内BNB不足':
        #transfer_usdt: 需要购买的usdt金额
        #i: bnb_usdt现货交易对的序号
        supply_bnb(transfer_usdt,i)
