掐客說到Average Down,我想起了不久前和一個真高手的聊天
這絕對是個高手，20多年的經驗，隻玩DT，我見過的有單日100K的記錄，談話的當天，我親眼看見他的P/L是 20K gain.
一般情況隻做幾個股，來回天天地倒騰，until volatility fade, 最近是AAPL， POT， CLF， ANR.
他說他每次進場，500股，然後，看市場，板塊，sibling, 如果反向了，再加碼，usually until 2000 share.
但是，有個mental stop, that is the point at which indicates the trade is bad ( trend is reversed. )
基本的精神/信仰，就是股市不是很trend, 大部分情況是 reverse to mean.
要是Average down 真是許多書本裏說的毒藥，這老兄怎麽可能生存那麽久？還以此為生？而且還住在富人區的豪宅裏？
• 是不是因為他隻作DT? -red_lanterns- ♂

It all depends on your size. If your hold 1 million on a volatile stock, 10% fluctuation would be $100k difference
NO NO NO!!! You shouldn't average down on EVERYTHING!! PLEASE don't do it, it may kill you eventually.
In this business, DICIPLINE is the most important thing I thin:
If you are a day trader, you have to clean up positions before mkt close. For me, I'm a trend or momentum follower(hold position anywhere from few hours to few weeks), you have to take lost, no matter how much, when trend changed direction or momentum faded.
Yes, as human being, it's hard to control your emotion.
Dicipline, it's easy to SAY than DO.
Not long ago, I bought etf BZG, and heavy, all because I THINK markit should go down since it already went up so long even though BGZ still weak on both long term and mid-term, even though it's short term still weak like hell and against my usual style. Eventually I had to take loss(about $80k) at around 8.40 two weeks ago because the TREND(down) just kept lasting, like forever. And I quickly switch to stronger stocks like MCP, SHZ, NVDA, and quickly made $150k back.
If I stay with BGZ, I would have lost even more right now in stead of make it back.
Anyways, if want to make money in this business, you HAVE to be GOOD enough. And it apply to any business.
