Thanks to the forum for allowing me some *room to move* to discuss Trading Philosophy and Psychology. I'll try not to abuse the privilige.
We can't be one person outside the trading room and someone else inside. First-class traders are almost certainly first-class people in life, albeit in their own way. ******************************************************************** For Dimitris, the *Maestro of Generosity*; you shamed me into a generous act. For every other generous contributor to the AmiBroker community; past and present. For all who posted in this topic; you gave of yourselves. For Tomasz who started it all and sustains it by his breath; *a creative bubble in the Universal Flux*. For the forum. ******************************************************************** Bill, An insightful question. You asked for it! I'll reverse the order this post and provide the *waffle* first. Hard-nosed rationalists just scroll down; your bits either at the bottom or coming in another post. (I'm starting to get bored with myself so the Psychology of Trading series will end in this session). My wife is a piano teacher and sometimes we discuss the philosophy of teaching. I provided her with a visual mnemonic to help her focus on the essential pedagogical path. I call it the *Triangle of Success*. At each point of the triangle either of the words, THEORY, PRACTISE OR PERFORMANCE is inscribed (outside the triangle so that the peaks point at the words). Performance is at the apex. In the centre a circle that touches each side of the triangle once is drawn and it has a single arrow head pointing anti-clockwise to indicate circular motion (progress). The arrow head is in the bottom left section. Symbologists would recognise the circle as Erebus; eternity or perpetuality. The white space within and without the shape isnot(Null). It is the *co-joined twins* (a triplicity in truth) or the *dual zeros*; the special case of zero signed in maths as infinity. In its primal form whitespace (the quantum state?) is energy and chaos. In modern culture, especially business culture, we would recognise the concept that the mnemonic encapsulates as continuous improvement. Continuous improvement is achieved by the repetitive cycle of theory, followed by practise followed by performance, which is the *testing ground*, also known in my school as the *burning ground*. The testing ground is the place where the inflated ego is sloughed off under the onslaught of reality (trading) and back to the drawing boards we go. For specific applications a small cross is inscribed in the centre of the circle to stand for any specific objective (trading goal?). This represents the fact that we progress by binding theory, practise and performance to a specific and particular goal. The cross symbolizes that unbounded chaos is drawn from the four quarters and focused at the central (objective) point. Unlike academic study, progress on *The Path of Success* is not linear or consistent. Development is a circular procession around the goal (circuambulation). Often quantum leaps in progress are experienced, usually at the least expected point in time. Of course the specific goal is not written within the circle, it is emblazoned within our SELF. How do we use this? Anyone who can't see the uses for it doesn't need it. Admonition! Money is not wealth. Money is a tool. Use it to help yourself, your family and loved ones, friends, neighbours, community, the nation and the world. Then right will be on your side and *right is might*. Be generous with what, as traders, we earn so easily; don't cast your pearls before swine though. That is the price we pay for having so much fun while most other people have to work for a living. Anyone who is interested in following up on the topic should maintain a reading list from amongst the plethora of personal development material available. Anything from Tony Robbins to the spiritual texts or religious scriptures is of inestimable benefit in attaining self-knowledge and hence self-discipline. Two of my favourites are the late great novelist Carlos Casteneda and also the late Psychologist Carl Jung; one of the greatest human beings of the last 100 years in my book. They are definitely not everyones cup of tea and people should choose their own favourites. Beware of fakirs though. The foothills surrounding *Mt Olympus* abound with them. **************************************************************** The *calender effect* and general comments. The calender effect is old hat. I assumed every trader in the forum who was interested in exploiting it had already done so or abandoned it as not profitable. It hasn't been near the top of my lists so I haven't had a go at it before, but, any specific market behaviour that is significant with 99.9% confidence levels is worth investigating in my book. Of course it is only viable as a trade if large enough movement is also there. I realise the older hands are only interested in a winning system, if at all, although my work nearly always contains a sprinkling of original material or old material presented in new ways. I have provided some commentary for the benefit of newcomers that is mainly straight out of the textbooks. Perhaps we can manage to squeeze a new tune from an old fiddle. Keep in mind that a lot of tested hypotheses don't get a pass mark, so the odds are against finding a winning system on any single *project*. I should also acknowledge the work of Arthur A Merrill once again; his efforts were an outstanding achievement at the time that he wrote. I'm drawing from his work, which is readily available in print, although I had already formed an opinion on calender cycles long before receiving confirmation from other analysts. General theories on market behaviour act as a creative stimulus to our trading and are a good starting point. Technically speaking, as Fred says, the why is not as important as the when and the what. However, as Sebastian has pointed out, starting with a why is a more fruitful approach than blindly crunching numbers, although the Freddites might find ways to climb all over me on that one. We can hold many general theories of market behaviour. They are not absolutes; only relatives. They need not be true and any or all arguments they contain need not be true. We can in fact hold contrary market theories all at the same time. The proof of the pudding is in the eating. Different theories evolve different trading systems that collectively comprise different trading styles. Trading different systems and/or different markets is the freelance traders equivalent of diversification (once applied with sophistication). A master trader can move between styles with aplomb. ********************************************************************* Discussion of a possible *Calender Effect* (CE) trading system. 1. Approximate *textbook* process flow: General theory of the market > specific theory (model) of the market > hypothesis > test the hypothesis > list all possible trading systems derivable from the hypothesis (still allow creative thinking at this stage) > test all possible systems (objective process commences) > optimise all or only the most promising systems > statistically evaluate top model(s) (100% objective filter) > out of sample testing of top model(s)> trade system > evaluate intitial trading performance > add system to a balanced portfolio (freelance style portfolio). It's a near certainty that I will only walk CE through the initial steps. 2. General theory of the markets No1 (includes additional points to my previous post). The behaviour of markets in the major western cultures is similar (USA, Australia, UK & others?) ( I don't comment on other markets because I haven't lived in those countries and don't understand the psyche the way I understand the psyche of the above group. That doesn't place any relative value judgement on other cultures). The markets are moved by institutional investors who control the major portion of the money. Institutional behaviour has characteristics that can be utilised by freelance traders. Institutional investors are people and will exhibit some behaviours typical of people in general. Based on personal observation of institutions, people and people in institutions I expect markets to exhibit some of the following behaviours to some extent: Institutions have budget and report cycles (weekly, monthly, quarterly, yearly?) Institutions are bound by rules of governance and obligations. It is not in the interests of institutional players to stick their heads up out of the trench. Institutions set employees targets which are benchmarked against industry norms. People have short memories. People *work* from Mon Fri, 9-5. People get Mondayitis and Fridayitis. American markets have high levels of insitutional participation. American equities have high liquidity (frequency) so they readily approach statistical validity for the institutional rule. The headline market indices are logically invalid but emotionally meaningful to investors (they are on prime TV every night of the week). There are many more similar observations. I have only provided a few as examples. 3. A specific market theory. (a) For American equities, with high liquidity, a calender effect will be readily observable and consistent . (b) The daily bar is the primary and natural time cycle of the American equity market(s). Intraday and weekly bars are the natural micro and macro cycles. 3. Hypotheses NORTH AMERICAN EQUITY MARKETS WILL HAVE A SIGNIFICANT BEARISH BIAS FROM THE CLOSE ON FRIDAYS TO THE CLOSE ON MONDAYS. NORTH AMERICAN EQUITY MARKETS WILL HAVE A SIGNIFICANT BULLISH BIAS FROM THE CLOSE OF TRADING ON MONDAY TO THE CLOSE OF TRADING ON FRIDAY. (At this stage there is no need to over state the hypothesis as there is plenty of scope during design and optimisation to test as many alternatives as we can think of and have the patience for. No attempt is made to formalise the process according to mathematical norms. It also provides me with an easy escape route from a probably well deserved pummelling from the mathematicians). 4. Test the hypothesis. >From the work of Merrill and Colby and others: Mondays are bearish with statistical significance. Fridays are bullish with statistical significance. Intraday trends measured on a half-hourly basis have a bias with the open more likely to be bullish than the close. The Monday close is the most bearish close of the week. The caveat is that IT may have changed the nature of the markets and the calender effect may not survive. The data set available ex the IT revolution, say 1995, approaches the limits of statistical validity for Mondayitis i.e. 12 years x 50 Mondays = = approx 600. Divided in two for design/optimisation plus out of sample testing this is not sufficient data for my liking so some older data will have to be accepted into the set. 5. List all possible trading systems that can be derived from the hypothesis. In this case study I will only provide two, at least for the moment anyway. SELL A MARKET (INDEX) AT THE CLOSE ON FRIDAY AND COVER AT THE CLOSE ON MONDAY. BUY A MARKET (INDEX) AT THE CLOSE ON MONDAY AND SELL AT THE CLOSE ON FRIDAY This suggests that the combined trade, bearish on an index over the weekend and bullish on an index Tues-Fri could make an effective trade. In the combined trade the traders capital would be invested 100% of the time rather than being idle on weekends i.e. 2/7 of the time. Colby, in fact, proposes and *tests* the Mon Fri bullish trade, using MetaStock software. The stock selected by Colby as the vehicle for this trade is the DJIA. Colby's results indicate his system *beats the market*. ********************************************************************* Commentary on the proposed trades. The weekend bearish trade would have less movement than the Mon-Fri bullish trade. Depending on the commission paid by individual traders it is likely to be susceptible to *profits* being eaten up by transaction costs. Both trades are liesurely trades, as they buy and sell the close. For that reason slippage is likely to have minimum or little effect on outcomes. Trading the indexes provides good liquidity, consistency and ease of processing e.g. data is readily available and there are no null data values to deal with. Membership survival of index data that travels back into the distant past is an issue however. If initial testing justifies further effort other potential trades can be considered: Do individual stocks piggy back the CE trends? If so can a determining factor be isolated for the group of stocks that out perform the CE of the index to which they belong? What effect will leverage have on profitability? Will indexes with high institutional participation perform differently to others? Is the CE effect, as defined in the hypotheses, biased further by the preceeding weekly/daily/intraday trends? Opportunities for optimisation can also be considered at a later stage: Will finessing the entry and exit times improve performance? Will indexes with higher volatility perform better? ************************************************************* Initial testing (provisional draft subject to change). Step1. Test the hypotheses. Attempt to duplicate the results of Merrill and Corby in various indexes, including obtaining some preliminary metrics e.g. Typical % gain/loss and number of rises/falls for weekly periods. Typical % gain/loss and number of rises/falls for weekend and Mon Fri periods. The aim is to obtain sufficient data to estimate Chi-squared significance for both hypothetical patterns in a range of markets and also the likely range of profit or loss for a trade based on the fundamental hypothetical trade(s). ******************************************************************** Anyone who wants to join in publically or privately feel free. Use at your own risk, it may contain errors. Likely to be continued.
