20100127 一月學到的教訓

一月即將過完,這個月可以列入我交易生涯中十分重要的一個月份了。一個月內犯了幾個錯誤,當然往好處想是也學到了不少寶貴的實戰經驗。

首先是月停損設的太小,結果上星期就剛剛好打到,差一點無法下單。最後是跟同事們調口數才可以下,雖然部位只有原先的2/3左右,但真的還好有借,否則1/26的超大行情就吃不到了。也就靠這一根長黑K,一月份的損益整個逆轉回來。

其次是,策略上架及下架或是調整的太頻繁,結果回測賺的時候都沒賺到,一上線賠全都賠到了。而十二月份下架的策略反而表現的比目前上架的還好,但當初只是想有類似概念的策略,所以就只留覺得較好的下來而已,卻沒想到一月的損益會差不少。

目前把策略從原先的9支再放大到15支,不輕言下架,口數也不亂調整了…=_=”

有種把我打到破Drawdown時我再來檢討!!

目標希望能把趕緊將策略數衝上20支,逆勢的策略占整體的10~20%左右。

20100118 Beyerdynamic DT860入手!!

2010/01/18 4 留言

前陣子忽然在網路上看到一篇錄音的文章,害我一直也想來試試。看一看,硬體設備上似乎是需要一個好一點的耳機和一台錄音卡。於是我就開始請朋友推薦一下,因為這方面我真的是一完全的沒概念。

原先同事的朋友推薦的是AKG K601或K701,但後來在網路上爬文時發現AKG好像不太適合我要聽的Metal或是Rock,只要親自跑一趟音悅音響聽看看再決定好了。後來店員推薦了幾支比較適合我需求的耳機,聽著Child of Bodom的Angles Don’t Kill,我只能說「靠!! 真是High啊」。這跟用爛喇叭放出來的比,還真的是有「那個」比雞腿的感覺…XD

「讓開,讓專業的來」,最後敗了Beyerdynamic DT860,雖然不便宜,但是一回家接上我的電吉他效果器試彈了一會後,真的是一整個爽。我終於可以不用接那爛音箱了,而且多晚玩吉他也不用擔心吵到別人,Perfect!!

最後,還是得介紹一下今日的主角才行…

【DT860—DT系列的準專業機種】

如果說DT880與DT990是Beyerdynamic的專業器材(在這裡並非指錄音室等領域上的專業,專業領域上Beyerdynamic尚 有DT PRO系列),那麼新的DT860就可以說是準專業機種了。DT860的聲音走向可說是幾乎承襲了Beyerdynamic一貫的音質設計,但與新版的 DT990一樣,在聲音密度與低頻銜接上做了改良。唯一不同的,DT860的聲音比較活潑,所以適合聆聽像rock、pop和jazz等熱鬧有趣的音樂。

DT860
動態開放式
頻率響應5~35,000Hz

20091225 事業與生活

今天在朋友的facebook上看到王文華的一篇文章「被延遲的快樂,不會產生利息」,就順便回了一下自己的想法…

=========================================

「被延遲的快樂不但不生利息,反而連本金都沒有了。」,這讓我想到有一本蠻有名的書「先別急著吃棉花糖」裡面所提的「延遲享樂」觀念,剛好跟王文華的想法相左,挺有趣的。

如果能無憂無慮的過生活,我想應該很少人會願意每天辛勤於工作。但現實是大部分的人都還是需要工作讓自己的生活更好。還有很多人的現實是連養活自己都很辛苦了,更別說如何去享受人生了。

當然,每天為了工作、為了升遷、為了賺錢並沒有保證就能得到想要的結果。有可能最後是事業不但普普,結果還要賠上了自己的青春。又或著是事業成功了,但人生的其它部分也全賠上了。

但相反的,若不多為事業煩一點心,真的遇上了職場環境大變動時,又能拿什麼實力去跟別人拚呢? 上帝最公平的事就是給每個人一天24hr的時間,願意投資在那裡的時間多就愈可能在那方面得到愈多成果,一切都是Trade-off。

人生的本質就是一場賭注,即然是場賭注就必然伴隨著風險,永遠都沒有絕對安全的路。想要得到什麼就得看自己先願意放棄什麼,然後下好離手後等著命運來開獎。人生不像考試制度一樣有標準答案,沒有人知道自己選擇的路最終會走到那裡。所以我覺得只要是忠於自己的感覺,最後不論結果如何也不會後悔就夠了。努力的過生活很棒、努力的拚事業很好,反正只要不虛度人生的每分每秒就是對自己最大的恩典了。

或許最完美的境界是在工作與生活間達到讓自己最舒服的平衡點吧。但在這之前,可能需要許多時間和嘗試做調整,呵呵…

哀!! 我擔心的事情終於發生了,晚上一接到我爸的電話就知道大事不妙…

上星期回嘉義時,他就感冒了,後來帶去醫院做健康檢查時就情況不太好,沒想到這次回去真的是見他最後一面。

從我國小五、六年級就陪伴我們到現在,也算是一隻高齡狗了,謝謝你給我很多快樂的回憶…

我會永遠懷念你的……

幹! I can’ t stop crying…

20091213 [轉貼]Trading Wisdom of William Eckhardt

Original article : http://www.thekirkreport.com/2008/02/trading-wisdom.html

Although I remember reading the interview many years ago, I so much enjoyed it again. His perspectives about trading are unique and offer wisdom that you won’t find anywhere else.

Here are just a few quotes that I think you’ll enjoy:

“If a betting game among a certain number of participants is played long enough, eventually one player will have all the money. If there is any skill involved, it will accelerate the process of concentrating all the stakes in a few hands. Something like this happens in the market. There is a persistent overall tendency for equity to flow from the many to the few. In the long run, the majority loses. The implication for the trader is that to win you have to act like the minority. If you bring normal human habits and tendencies to trading, you’ll gravitate toward the majority and inevitably lose.” – William Eckhardt

“It’s much easier to learn what you should do in trading than to do it. Good systems tend to violate normal human tendencies.” – William Eckhardt

“One common adage on this subject that is completely wrongheaded is: you can’t go broke taking profits. That’s precisely how many traders do go broke. While amateurs go broke by taking large losses, professionals go broke by taking small profits. The problem in a nutshell is that human nature does not operate to maximize gain but rather to maximize the chance of gain. The desire to maximize the number of winning trades (or minimize the number of losing trades) works against the trader. The success rate of trades is the least important performance statistic and may even be inversely related to performance.” – William Eckhardt

“The people who survive avoid snowball scenarios in which bad trades cause them to become emotionally destabilized and make more bad trades. They are also able to feel the pain of losing. If you don’t feel the pain of a loss, then you’re in the same position as those unfortunate people who have no pain sensors. If they leave their hand on a hot stove, it will burn off. There is no way to survive in the world without pain. Similarly, in the markets, if the losses don’t hurt, your financial survival is tenuous.” – William Eckhardt

“I know of a few multimillionaires who started trading with inherited wealth. In each case, they lost it all because they didn’t feel the pain when they were losing. In those formative first few years of trading, they felt they could afford to lose. You’re much better off going into the market on a shoestring, feeling that you can’t afford to lose. I’d rather bet on somebody starting out with a few thousand dollars than on somebody who came in with millions.” – William Eckhardt

“In many ways, large profits are even more insidious than large losses in terms of emotional destabilization. I think it’s important not to be emotionally attached to large profits. I’ve certainly made some of my worst trades after long periods of winning. When you’re on a big winning streak, there’s a temptation to think that you’re doing something special, which will allow you to continue to propel yourself upward. You start to think that you can afford to make shoddy decisions. You can imagine what happens next. As a general rule, losses make you strong and profits make you weak.” – William Eckhardt

“If you’re playing for emotional satisfaction, you’re bound to lose, because what feels good is often the wrong thing to do. Richard Dennis used to say, somewhat facetiously, “If it feels good, don’t do it.” In fact, one rule we taught the Turtles was: When all the criteria are in balance, do the thing you least want to do. You have to decide early on whether you’re playing for the fun or for the success. Whether you measure it in money or in some other way, to win at trading you have to be playing for the success.” – William Eckhardt

“Trading is also highly addictive. When behavioral psychologists have compared the relative addictiveness of various reinforcement schedules, they found that intermittent reinforcement – positive and negative dispensed randomly (for example, the rat doesn’t know whether it will get pleasure or pain when it hits the bar) – is the most addictive alternative of all, more addictive than positive reinforcement only. Intermittent reinforcement describes the experience of the compulsive gambler as well as the future trader. The difference is that, just perhaps, the trader can make money.” However, as with most affective aspects of trading, its addictiveness constantly threatens ruin. Addictiveness is the reason why so many players who make fortunes leave the game broke.” – William Eckhardt

“Don’t think about what the market’s going to do; you have absolutely no control over that. Think about what you’re going to do if it gets there. In particular, you should spend no time at all thinking about those rosy scenarios in which the market goes your way, since in those situations, there’s nothing more for you to do. Focus instead on those things you want least to happen and on what your response will be.” – William Eckhardt

If you don’t think these principles are true, you haven’t been trading very long. Print these out and refer to them often.

20091206 [轉貼]You’ve got to find what you love, Jobs says

[原文]
Stanford Report, June 14, 2005

This is the text of the Commencement address by Steve Jobs, CEO of Apple Computer and of Pixar Animation Studios, delivered on June 12, 2005.

I am honored to be with you today at your commencement from one of the finest universities in the world. I never graduated from college. Truth be told, this is the closest I’ve ever gotten to a college graduation. Today I want to tell you three stories from my life. That’s it. No big deal. Just three stories.

The first story is about connecting the dots.

I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in for another 18 months or so before I really quit. So why did I drop out?

It started before I was born. My biological mother was a young, unwed college graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking: “We have an unexpected baby boy; do you want him?” They said: “Of course.” My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would someday go to college.

And 17 years later I did go to college. But I naively chose a college that was almost as expensive as Stanford, and all of my working-class parents’ savings were being spent on my college tuition. After six months, I couldn’t see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes that didn’t interest me, and begin dropping in on the ones that looked interesting.

20091128 我們真的了解全球暖化的真相嗎?

全球暖化這幾年一直被認為是環境保護的重大議題,不過當大多數的主流媒體都持有相同論點時,我們也應該聽聽其它不同的聲音才對,至少我們不該一眛的直接接受主流媒體所要灌輸給我們的觀念。全球暖化是我們很直接可以感受到的事實,然而問題在於,暖化背後的成因卻可能不是那麼的顯而易見。我們應該保留自己的判斷權力,給自己一些思考的機會吧。

http://mag.udn.com/mag/world/storypage.jsp?f_ART_ID=72971

2007/06/15
自從美國前副總統高爾所拍攝的「不願面對的真相」(An Inconvenient Truth)勇奪奧斯卡金像獎,全球暖化就成為顯學,抗暖化躍居當今人類共同面對的首要課題,排山倒海而來的檢討聲浪,令各國政府與大企業都不敢輕忽。

不過,並非所有的科學家都贊同高爾的觀點,還有許多科學家並不認同該片災難式的拍攝手法。就連一些與高爾過從甚密的學者專家,對於目前在全球風起雲湧的抗暖化浪潮也漸漸感到不安。他們坦承,這部影片中有些資料並不正確,也有技術上的瑕疵。

事實上,科學界對於全球暖化問題的看法存有歧見,只是在環保人士的大聲疾呼、政經力量的強勢介入、以及新聞媒體欠缺平衡報導之下,此一議題已偏離科學範疇,反而被賦予道德化的宗教色彩,似乎全球所面臨的是一場攸關人類存亡的聖戰。

在抗暖化聲勢如日中天之際,同時也有愈來愈多科學家挺身而出,呼籲大家讓此議題回歸科學,在沒有足夠證據支持論點的此刻,還不宜妄下定論,更不該以災難式的預言發佈警訊,以免誤導主政者的決策判斷,反而打擊第三世界國家的發展。

暖化 是自然週期還是人為惡化?

關於全球暖化的論述,在科學界有三點共識:一、自19世紀晚期以來,全球氣溫上升了一度左右;二、在此同一段時期,大氣層中的二氧化碳增加約30%;三、二氧化碳會助長未來的暖化現象。

但對這三項共識的解讀,科學界分為兩陣營。一個陣營認為全球暖化的問題嚴重,而且是由人為因素所造成,必須立即採取行動,以免持續惡化而釀成災難。這也是高爾在「不願面對的真相」中所不斷強調的論點。

另一個陣營則認為,從三項關於暖化的論述來看,全球暖化現象的確存在,但無足夠證據證明人類是罪魁禍首,人類是否有扭轉自然的能力也令人懷疑,這更無法支持「世界將面臨毀滅性災難」的預言。

引爆科學界對全球暖化激烈論戰的關鍵之一,是科學家Michael Mann於1998年所發表轟動全球的言論:近百年來的氣溫升幅是過去1000年間最大者,1990年代是這1000年中最溫暖的10年,1998年則是最溫暖的一年。他認為,這不能以自然因素來解釋,而是因人類活動所造成。

Mann所展示的氣溫走勢圖尤其令人印象深刻。圖形顯示過去這1000年間的氣溫變化大致穩定,但是在20世紀時卻呈現急遽上揚,整個走勢就像曲棍球桿一般。

2001年,聯合國旗下的「跨政府氣候變遷小組」(Intergovernmental Panel on Climate Change,IPCC)決定採用Mann的研究結果做為官方觀點,納入該年公佈的氣候變遷評估報告。然而,對Mann的說法有意見的科學家不在少數,其中批評最力者是兩位加拿大的科學家Steve McIntyre和Ross McKitrick。

為了釐清真相,美國眾議院能源暨商業委員會委託知名統計學家Edward Wegman進行公正的第三方驗證,Wegman邀集了一群統計學家組成工作小組,並且同意在不收取任何報酬的情況下展開研究。最後,他們證實加拿大科學家的批評不假。

Wegman指出,1990年代是千年以來最熱的十年,1998年是千年以來最熱的一年,這兩種說法都不能成立。他認為,Mann並未受過統計方法的訓練,在研究期間也未尋求統計專家的協助,因而出現錯誤。備受歐洲推崇的義大利科學家Antonino Zichichi在4月底於梵諦岡舉行的「氣候變遷與發展」研討會上直言,IPCC所採用的模型前後不一,以科學的觀點來看毫無意義。

20091126 [讀書心得]塔木德-猶太人的致富聖經

看完這本書,對於猶太人真的是肅然起敬,下面大概整理了書中的一些重點,有興趣的話可以買書來看看,花少少的幾百元而已,買到的觀念搞不好會改變你的一生呢,很值得的一筆買賣啊,呵!!

塔木德:
•    身體依靠心而生存,心則依靠錢包而生存。
•    殘害人們的東西有三樣:煩惱、爭吵、空錢包,其中空錢包害最甚。
•    錢不是罪惡,也不是詛咒,它是給予人們的一種祝福。
•    錢雖非盡善盡美,但也不致使事物腐敗。
•    金錢平等,因此,人格平等;懷有賺大錢的欲望是好的。金錢對於任何人來說,都是平等的,它沒有高低貴賤的差別。
•    金錢不神聖,不是高不可攀的聖物。
•    吝嗇有時候和節儉一樣,是一種優秀的口德。
•    上帝把錢當禮物送給我們,目的在讓我們購買這世間的快樂,而不是讓我們購買這世間的快樂,而不是讓我們摳起來還給祂的。
•    當富人不敢花錢的時候,他就等於是個貧窮的人。
•    沒有能力買鞋子時,可以借別人的,這樣比赤腳走的快。
•    借錢給朋友,將以失去友情當作利息。
•    暫時放棄一些利益,是為了得到更多的利益。
•    永遠都是賺大錢的兩個關鍵:女人和嘴巴。
•    男人是這個世界的中心,但女人卻是男人的中心。
•    人們只能用強勢的力量去強迫自己,卻不能強迫別人;聰明的人要求別人做事時,必須像女人一樣的溫柔。
•    思考時請感情離開,因為,你需要的是理智。
•    如果一個人算不清帳,他的帳就會找他算帳。
•    請主給我磨難,考驗我對主的信仰;請主給我苦痛,讓我和普通人不一樣;請主給我逆境,讓我擁有成功。
•    人生是要犯錯誤的,不犯任何錯誤的人,注定是一無所成的人。
•    當機會來臨時,不敢冒險的人永遠是平庸之輩。
•    今天將要發生的事我們都還不知道,何必為明天而煩惱。
•    生命有限,時光荏苒,只有奮鬥不已,方能生生不息。
•    流下眼淚撒種的,必歡呼收割;那流著眼淚走出去的,必要歡呼地回來。
•    我們無法左右命運,但也不要被命運左右。
•    超越別人的人,不能算真正的成功;超越自己,才是真正的成功。
•    想變得富有,你就必須向富人學習。就算在富人堆裡站上一會兒也好,至少會沾到富人的氣息。
•    葡萄長的愈豐碩,就愈低下頭。同樣的,愈有智慧的人,便愈懂得謙虛。
•    善於思考問題,多想問題是商人應該做的事情。為了避免做錯決策,應該全面地看問題。
•    凡事自己不去思考和判斷,等於把自己的腦袋交給別人。
•    成功沒有捷徑可走,但是卻可以有多條路徑供你選擇。
•    今天就是最後一天,永遠不要等明天,因為,沒有人知道明天會是什麼樣子。
•    日光之下,快跑的未必能贏,力戰的未必得勝,聰明的未必得糧食,機智的未必得資財,靈巧的未必得喜悅;眾人所得到的,只是當下的機會。
•    最值得依賴的朋友在鏡子裡,那就是你自己。
•    多走幾步,就會看到更多的好風景。
•    會享受生活的人,才能夠更好的去創造生活。
•    人的能力不是天生的,是從小培養的。
•    遵守契約,尊重契約,你的收穫將不只是尊重。
•    人最大的痛苦不是被人欺騙,而是不被人信任。
•    你必須知道的三件事:誰是領導者? 什麼是遊戲規則? 由誰來執行這規則。
•    假如所有人都向同一個方向行走,這個世界必將傾覆。
•    一個人的價值,絕不低於所有任何人的價值。
•    不要模仿,如果你要成功,你應該朝新的道路前進,不要跟隨被踩爛的成功之路。
