基于easytrader的核按钮函数，测试代码

功能实现：开盘前将所有持仓标的挂跌停出。

一键清仓

python代码如下；

1.实现四舍五入，5进位，不要忽略前一位是偶数就不进的bug

def round_up(n, m):
    n = str(n)
    if len(n) - n.index(".") - 1 == m + 1:
        n += "1"
    return round(float(n), m)  
if __name__ == "__main__":
    print(round_up(0.125, 2))

2.获取持仓信息，并完成下单

def round_up(n, m):
    n = str(n)
    if len(n) - n.index(".") - 1 == m + 1:
        n += "1"
    return round(float(n), m)  

def test_sell(code,price,amount):
    dlg.type_keys('{F2}').type_keys(code).type_keys('{ENTER}').type_keys(price).type_keys('{ENTER}').type_keys(amount).type_keys('{ENTER}')

def position_0():
    #获取资金持仓
    today_total_assets = user.position
    for i in range(len(today_total_assets)):
        code = today_total_assets[i]['证券代码']
        amount = today_total_assets[i]['可申赎数量']
        if amount==0:
            continue
        price = today_total_assets[i]['市价']
        price_down = round_up((price*0.9), 2)
        print(str(code)+' '+str(price_down)+' '+str(amount))
        #1.etrader下单
        user.sell(code,price = price_down,amount =amount)
        #2.修改的xiadan
        test_sell(code=code, price=price_down, amount=amount)
    

#登录自动交易模块
if __name__ == "__main__":
    #1.初始化
    #1.1 同花顺客户端初始化
    user = easytrader.use('universal_client') # 同花顺客户端
    user.prepare(user='', password='', comm_password='', exe_path='C:\同花顺软件\同花顺\xiadan.exe')

    app = Application("uia").connect(title_re = "网上股票交易系统5.0")    # 按照窗口句柄链接 handle
    dlg = app.window(title_re = "网上股票交易系统5.0")   
    #一键清仓
    print(time.strftime('%Y.%m.%d %H:%M:%S ',time.localtime(time.time()))) 
    position_0()
    print(time.strftime('%Y.%m.%d %H:%M:%S ',time.localtime(time.time())))
