If and when you do check them out, the following may be helpful. I wrote it nearly twenty years ago in order to help beginners understand that daily bars do not just spring forth whole; they are formed by the trades that take place during the day, and knowing how traders arrived at a closing price can be and often is crucial (the intraday "bar", on the other hand, is an invention of software engineers and has no particular meaning as there are no closes until the end of the session, or, in the case of futures, the end of the week; this will be of no importance to you if you don't trade intraday).
Whether you get anything out of bar or candlestick analysis may depend in large part on whether you are better at inductive or deductive reasoning. If I'm exploring something new, for example, I'll look for specific examples of whatever it is I'm investigating, then formulate preliminary hypotheses which are consistent with what I'm seeing. Then I'll apply those hypotheses to further examples in an attempt to come up with general principles. If those general principles hold over time, I'll ignore specific examples almost entirely unless I find one or several that seem to suggest that the general principle may have changed (or may not have been valid in the first place). Which is why I get very little out of the price bar/candlestick analyses provided by "experts" in books.
But whether one conducts his analysis via deductive or inductive reasoning, analyzing a given price bar/volume bar pair -- while interesting and even instructive -- is largely a waste of time in the larger scheme of things if one is trying to determine what it is he ought to be doing about whatever conclusions he arrived at. The reason for this is that a given bar is not anywhere near as important as the bars which follow it.
There is confusion, for example, regarding the significance or importance of high volume on a down bar. Is it a good thing? Or is it a bad thing? And the answer is that it depends. It depends on where the bar is, how long it is, where the open is on the bar, where the close is, the spread between the open and close, the distance between the close and the low, the distance between the open and the high, where support and resistance lie, what the market's doing, how strong the volume is and at what point the volume became strong etc, etc, and so on.
But even if one decides that the bar is a good thing, that decision can be no more than a preliminary hypothesis. The rubber meets the road in the bars that follow. Does volume increase or dry up? Does the price continue to fall or does it rebound? If support is being tested, does it hold? As with the beginner who asks whether a large trade is a buy order or a sell order, it doesn't really make any difference since one side of the trade can't exist without the other (otherwise it's just pending). What matters is the immediate effect on the stock. If it rises, the trade represented buying pressure. If it falls, it represented selling pressure. But it takes a few minutes to find that out. Is there enough demand to absorb that supply and propel the stock higher? Then hang on for dear life. Is there not enough demand to absorb that supply and propel the stock higher? Then get the hell out without hesitation and stand aside until you see where the decline tails off.
Even if you know the "meaning" of strong volume and a long bar (or weak volume and a long bar, or strong volume and a weak bar, or strong volume with a long bar in which the relationship of the open and close to the high and the low are . . .), you have to arrive at a set of general principles or else you'll never be able to act. And the ability to act decisively and with conviction is essential to maximizing profits. Understanding this can be a challenge even if one is unusually bright. With experience, that understanding will come if one applies himself enough. And there really is no way to understand it without experience. But the experience required to understand all this needn't take years. At the very least it can be accelerated by sitting down in front of a screen which contains a bar and volume chart (no indicators of any kind) and “replay” software. Set the speed fast enough so that you won’t feel as though you’re watching paint dry. As the daily bar forms, along with its volume bar, you can more easily develop a sensitivity not only to the struggle between bulls and bears but also the relative strength of each from trade to trade. Even a half-hour of doing this will lead to a great many Ah-Ha moments which are difficult if not impossible to reach by looking at static charts in hindsight.
