There are immediately problems that occur with some of the thinking within this post.
1...what about corrupted data?
2...the use of the words, ....."most likely", "usually", "most" these are words that are directly equivelent to chart set-ups, 123 reversals "usually,mostly, most likely" do XYZ.
3...VALUE, and the closeness of the numbers within financial markets are not CORRELATED in any shape or form for the vast %age of time. You will have gross overvaluation, gross undervaluation, and parity ......parity represents a small fraction of time, and is difficult to calculate with any accuracy.
I will answer your points brought up one by one.
1) I use EOD data and very seldom have I gotton corrupted data. Very seldom has it every caused me any problem in my trading. Maybe 2 times in several years.
2) The words "usually" "most likely" "most" ARE NOT equivelant to saying that that a chart pattern "most likely" will do so and so. Why is it not equivelant? Simply because basing a forecast on a grafical picture that prices have formed IS NOT the same thing as using numbers that exactly represent price action. Why? Because you will be subjective in determining a chart pattern and that subjectivity will "spill" over into any forecast. However, numbers are 100% objective empirical data. I don't have to think a stock made a low price of 13.50. I can "know" for a fact it did so. However, I may "think" a triangle is forming because I seem to "see" it but someone else sitting right beside me see's something else. And remember the forecast WILL be based on what is "seen" in a pattern. Just look at post 1,2,4, 5, 7,8,10,11, 12, 13, 20 to see how different people looking at the SAME chart see different patterns and remember if they trade with patterns they see then their forecast will be based upon what ever pattern they "see". That is why I say chart reading is too subjective and we have proof of it right here in this thread. You yourself said in post 30 "Technical Analysis as a whole, incorporating all the individual methodologies espoused still shows approximately a 50% expectancy. That is to say, it will either succeed, or fail."
A good 50/50 method would be to flip a coin. Heads I go long. Tails I short. I heard of a guy in the US that had fame for being quite an astute trader. You know his method? Swing a pendulum. If it swings one way go long. The other way sell or short-sell. However, you know what "really" was the success in his system? At the end of the day if a position wasn't profitable he kicked it out before the close. If it was profitable he kept it. So, his success really was he cut his losses and let his winners run. Now I can tell you this from experience you can trade successfully off numbers and and have a much higher rate of success than 50%. Of course numbers will be off when manipulation comes into the market and I will deal with that in a minute. When I say my "usually" is "NO WAY equal to the "usually" in chart reading" it is because one is based on something very subjective and the other is based upon something exact - a number. Think about this. Linda Bradford Rascke once said "The best indicator of price is price itself". Price is thus a leading indicator of near term future price (say for the next session). And one of the best I might say!
3) When I say value I am not talking about "true" what I am talking about is what people are willing to pay for something. I bought a new Avalanche. Sticker price was over 43,000.00, if I remember correctly. Of course, I bargined and used a 4000.00 rebate and ended getting the truck for 33,930.00 or somewhere near that price. Now I DO NOT think the truck is truely worth even 30,000.00 but I wanted it. I was willing to pay the price. I see value simply as what someone is willing to pay for something. When I said "value" that is what I meant. I am not talking about true value of a stock from say the perspective of fundamental analysis. If my truck example implied that then I was wrong for leaving that impression and you were right in your criticism. I should be clearer in the terms I use. NOw, if I were investing long term you can be sure I would be very interested in "true value" however, I am just along for a short ride so I define value in any stock as any price people are willing to pay for it. I don't care if it is "truely overvalued" at the price they pay for it I am only concerned with the "immediate" value. The reason price works as a good indicator for tommorrows price action is simply because price reflects "immediate value" but not necessarily true value from a fundamental analysis standpoint. Therefore please understand when I say "value" I am saying "immediate value-what someone is willing to pay at this moment". That being said and understood then it should be VERY clear that price and immediate value ARE in fact 100% correlated. Price IS IMMEDIATE VALUE, at least for someone, because that someone just bought it at that price. And all of this is empirical and can be measured EXACTLY and postulated onto a senario for tommorow. Nevertheless, manipulation must be taken into account. I will deal with that in a minute but first the lets look at your comments about the trend.
Until the trend ends, or encounters a correction, etc. The problem with a system as described by yourself is that you will still require an opinion on direction and duration, as reversion to the mean may very well take place, but only to a point far outside your original entry.
Price manipulation happens consistently by market makers as this is an easy way for them to make money, and this in itself will play havoc with a numbers system.
When a trend starts the numbers will show it. When it tops the numbers will show it. When it goes down the numbers will show it. The numbers show everything that actually happens to a trend along with any corrections. Now the numbers DO NOT neccesarily tell you "why" it happened but numbers can and do show exactly what happened. Numbers can be used to not only see a trend but to also measure the velocity of the trend. As velocity slows down chances are the trend will soon begin to slow. Just like an airplane that is taking off - the thrust and momentum carry it is a certain direction at a certain speed (velocity is speed in certain direction). In the case of the airplane UP is the direction. However cut back on the throttle and velocity will slow but the plane is still headed UP. The trend is still up. Nevertheless, cut back enough on the throttle (gas) and the plane will make a trend change and start down. Now speed, velocity, momentum of price in a trend can all be measured mathematically. Volume also is a number and acts as the gas (the throttle if you will) and it also can be measured for it is a number. I say a correct application of price numbers correlated with volume numbers and individual transaction volume numbers along with Bid/ASK price AND size can all help one to determine where prices are "most likely" ( and I mean more than 50%)to go. Along with the many averages such as averages of daily range, average high/low price etc can all help. And keep in mind these are ALL numbers not subjective patterns. And when I say "most likely" I mean more than 50%. More like 80% or above. At least that has been my experience in real trading not papertrading. Now a word about manipulation.
The point here is if you use market data, you will be manipulated, whether it be via a chart, price, whatever........your ability to be paid rests in the skill that you have in correctly calling direction and duration based on sentiment, manipulation, and momentum.
I would dare to say manipulation takes place in every stock, every day that it is open. Where you have specialists or market makers they will most certainly manipulate. Actually, I am glad you mentioned manipulation for I failed to mention it in my first post. Manipulation is there. But again, the numbers show manipulation. There exist moment by moment manipulation by the market makers and the specialist. Much of that sort of manipulation can be detected by learning to read level 2 screens on Nasdaq stocks, and by reading the Bid/Ask price correlated with size of BID/ASK and the volume of the individual transactions as they take place. Nevertheless, even the maniuplators work within support/resistance zone. Most of the time they don't just shoot a stock way up and then allow it to free fall all the way down (however sometimes they do). You will find that the "insiders" actually create the resistance and support levels. They come in with buying to support a falling stock and will dump supply on the market to stop a rise in price thus creating a resistance level while at the same time making a profit. Why in the world would they "stop" a stock from rising? Simply because the MM and specialist are charged with creating an orderly market. If they were to allow a stock to always shoot straight up and then straight down they would have the investing public afraid to put their money in a stock that is so volatile. Therefore, "smart money" must find a way to keep a market orderly while at the same time making a profit. They do this buy creating resistance/support levels. In other words, they become sellers when the public wants to buy and when the publics thirst dries up resistance is hit because supply (of insiders) overwhelms demand (of public). The price starts down. Guess who is selling on the way down? A scared public. Guess who is buying as it goes down? Smart money! Finally they come in and heavily support the stock buying up eveyrthing in sight. Their demand begins to overwhelm the available supply (of the public) as most of the public has sold (many at a lost I might add) and so the slide down stops right where the smart money wants it to stop at. Now, having said all this consider what I am about to say next: If smart money does indeed creates resistance and support as a mechanism to maintain order in the markets and yet allow them to make a profit then knowing support and resistance levels can be useful. And numbers measure EXACTLY support and resistance levels. As a matter of fact, you can even see how different stocks tend to trade different ways by simply looking at a chart (that is one area I have found charts to be useful in). Stocks seem to have a personality of their own. I suspect it is the way the specialist manipulates the stock. It is a reflection of his maniuplation. So, manipulation does exist and it displays itself in support and resistance levels and this can be measured. As a matter of fact an average of support and resistance numbers can be made and can be VERY profitable in determining at what price a stock is "likely" (and I mean more than 50%) to hit resistance. Also, there are simply days manipulation will run the numbers way out of the norm. All that has to be done on days like that is to plug the "new" empirical data into the software and allow it to recalculate factoring in the extremes in price that took place and give a "new" forecast that takes into consideration the new numbers.
One area we haven't touched on is the emotions. Emotions can and sometime do run a stock way up or way done and there is nothing the MM's or specialist can do to stop it. It has to run it's course until it runs out. In such a case one can plug in the new data and get a new forecast but one must understand that one is assuming more risk even with a new forecast until the emotions have run there course. However, many times more risk translate into greater gains IF you happen to be on the right side. That is why stop losses are neccesary and the discipline use them an overriding behavioural pattern for successful traders. Most traders are unsuccessfull because of a lack of discipline that results in not protecting their capitol. Remember the story of the trader above". His system was simple. The key to his system was discipline!
Have a great day!
