我试图在一段时间的True循环中设置一个变量（不是全局变量，这不适用于我的线程）。
基本上，while循环运行，购买硬币，等待直到macd指示器变为绿色以表示准备出售如果变量名为“waitwait”且if语句将此设置为true。然后，我想要的功能是它一次又一次地循环使用该变量集，直到我收到macd down信号，并且当两个语句在sell“elif”语句中都为真时，我希望系统运行elif语句（同时“waitwait”设置为True。
代码很长，主要代码在这里的“runrun”def语句中： https://github.com/TheRoboKitten/ZenAii/blob/master/development2.py
以下是代码示例：
def runrun():
waitwait = False
print('Waitwait set to False before sell and waiting on macd up signal before sell.')
