赌博,交易和Educated guess

 
来源: Nerazzurri 于 2024-03-16 09:12:00 

赌博,gambling, 是属于一种娱乐方式。在Wiki中它的定义是“wagering of something

of value on a random event with the intent of winning something else of value",

就是对随机事件的的随机猜测,对错完全是运气的因素。

交易,trading,是属于一种商业方式,比如常见的到义乌低价进货小商品然后加价卖到

欧洲,交易者有利可图,是因为supply demand mismatch。这种交易方式只要有准确

的市场调查,是比较容易盈利的。

股市中的交易也脱不开 Law of Supply and Demand. 比如TA中有一个indicator叫

Exhaustion Bar。An Exhaustion Bar is a bar which signals the exhaustion of the

trend in the current direction. In other words, an exhaustion bar is “A bar of the

last seller“ in case of a downtrend and “A bar of last buyer” in case of an

uptrend。简而言之,在downtrend中出现exhaustion bar就意味着短期内supply

短缺,股价止跌上扬的可能性大。反之,在uptrend中出现 exhaustion bar就意味着

短期内demand不再强劲,股价遇阻回落的可能性大。

我昨天说SOXL在42-ish是一个比较好的买点,这是一种educated guess-based on 

Exhaustion Bar。 用TA来说,图是这样的。每个绿色圈圈代表的就是Exhaustion Bar。

3/15/2024是昨天出现的Exhaustion Bar。在这之前的四次都是SOXL的绝佳进场点。

SOXL自3/11/2010年inception以来,这种Seller Exhaustion Bar总共出现了146次,

机率为4.14%。这146次中124次有比较大的upside,大概十天 upside有15%左右,

二十天upsid超过20%。具体如下:

SOXL总共出现Seller Exhaustion Bar的146次当中,2个月内ROI大于15%的可能性

多达124次,磨磨唧唧不输不赢是9次,输的可能性也有,是13次。所以成功的机率

是84.93%,不输不赢的机率是6.16%,输的可能性为8.9%。因为这是一种基于

probability的估算,所以我认为是一种educated guess而不是纯粹的random guess

 like gambling。

Leledc Exhaustion Bar,就可以加到你的chart里面了。附图:

需要指出的是,每个indicator对不同的stock或者etf的成功率是不一样的,因为他们的波动

率不一样。我只回测了SOXL和TQQQ,这个Leledc Exhaustion Bar对于寻找买点很有帮

助,对于寻找卖点也还可以,但比买点成功率差一些。这个indicator对于QQQ或SPY相对

差一些,因为他们的波动率小很多。对于个股我没有回测,我也不做个股。YMYD。
