资金管理的原则-盲目集中或分散管理是对资金的滥用。专注于头寸，仔细研究目标股票的细节，并精心操作是专业参与者最重要的资金管理和实际操作。
无论投资规模和投资水平如何，绝对不允许专业的短期交易者因盘中交易价格波动的诱惑而没有充分的准备。这里我们通过股票市场学习短期股票交易技巧，希望这里的总结对大家有所帮助。
1，当总体趋势下降时，不要追逐强势股票。但是，投资者应开始积极选择股票，并在市场稳定后为及时参与投机活动奠定基础。此时，有必要关注那些在股市中大幅下跌并且能够保持领先大盘并稳定它们的股票。
2，表示总体趋势活跃时的短期趋势。活跃交易的大势所趋，交易量大，个股大幅上涨，并且当股票涨停时有更多的股票，短期内往往很容易做。尤其是当电热板带有水龙头时，您可以抓住水龙头然后做。
3。当市场停滞并企稳时，有必要重新选择主要库存以形成较小的底部形状。单个股票的稳定时间显然比大盘的稳定时间更长，并且在触底之后，单个股票的趋势必须具有一定的独立性。
4，必须设置止损点。抢夺短期强势股票，在短期上涨后不久将其抛弃。如果他们不上涨，他们将在前一天购买最低的价格止损，最大损失为10％。建议的止损为5％。
5。短期经营旨在快速获利。它是无利可图的，不能迅速获利。这与目的背道而驰。这应该尽快摆脱交易。

The debugger caught an exception in your WSGI application. You can now
look at the traceback which led to the error.
If you enable JavaScript you can also use additional features such as code
execution (if the evalex feature is enabled), automatic pasting of the
exceptions and much more.
Console Locked
The console is locked and needs to be unlocked by entering the PIN.
You can find the PIN printed out on the standard output of your
shell that runs the server.
