When it metformin 500 mg dosage comes to charting, there are many different options for you to choose from. However, there are three types that are head and shoulders above the rest of them in terms of popularity. While you will occasionally hear about the other types of charts, about 99% of the time you will be looking at the following kinds of charting:
Line charts
Bar charts
Japanese Candlestick charts ( also known metformin hcl 500 mg dosage simply as "Candlesticks")
While they all can be useful, and which one you choose is a personal decision, you should know the difference between them all.
Line charts are by far the simplest form of charting that you will see. Of course, with simplicity comes less information. With the line chart, the various closing prices and plotted and connected. When you combine all of the closing prices together in a line like this, you get a very quick and basic glance at price movement. Below is an example of a line chart:

By looking at this chart, you can see that the AUD/NZD pair is rising in value. You can also see that it was being bought at a few places like the 1.2000 and 1.23000 areas. Congratulations! By noticing these kinds of things, you have just done your first piece of technical analysis!
Bar charts aren’t as simple as a line chart, but offer much more information as a result. A bar will show the open price, the close price, the high for the time period being plotted, and the low for the time period being plotted. For example, if you are looking at a bar on the daily chart, it shows what price the financial instrument was when the trading day opened, what price it was when the trading closed, as well as showing the range of trading. (Or, the highest to lowest prices made during that day.)
Bars have three lines that give all of this information. The bar has a center line that runs vertically showing the range. The top of the line shows the high for the period of time, and the bottom of the line shows the lowest price for that time period. There are also two small hash marks connected to the center line. On the left hand side of the bar is a small hash mark that runs horizontally showing the opening price. Alternately, the small line running horizontally off of the right side of the bar shows the closing price. Below is an example of a bar:

Looking at this bar, you can see that we opened the trading period near the very low. We then saw price drift slightly lower, and then race much higher. We then ended the time period towards the top of the trading range. There are some things that you can take form this bar. The range was fairly wide, and this shows there is volatility, meaning that trading is active. Because of this, conditions favor a move in the financial instrument. This gives you a chance to profit from your speculation in the market. If it isn’t moving, you aren’t going to be profiting.
The bar also tells us that price moved much higher during this time period. This gives us an idea of which direction we might be interested in going. In this case, buying. Of course, you will want to look at the overall trend of buy or sell bars over the chart to make a decision on which direction you want to trade, but as far as this time period is concerned, it is a resounding "buy".
The last thing you should take away from this bar is the fact that price closed near the top of the range. This not only shows that we were rising in price, but that the time period ended with traders still buying. This can often give a clue as to the direction of the next bar as well, as momentum can keep pushing prices higher.
Take a look at this example of a bar chart:

By putting this all together, you can see that price is rising, and that we have had several large positive bars (Also called bullish when buying is going on.) that made up this move. A lack of negative bars (Also called bearish when selling is going on.) shows that you want to be buying this pair if you are involved. There really aren’t too many reasons to sell this pair based upon this little bit of information. By glancing at this chart, you have established that it is in an uptrend, and most of the positive bullish bars are fairly strong as well. This chart shows that the Australian dollar is certainly rising in value against the New Zealand dollar.
Although candlestick and bar charts show the exact same information, a lot of traders prefer the candlestick method over the traditional bar chart. This is mainly because they are color coded on top of showing the open, close, high and low of a time period, which allows the trader to glance at a chart and see the trend much clearer.
The candlestick shows the range in the same fashion as the bar. There is a vertical line that shows the high and low of the time period. But the first thing you will notice that a candlestick also has a "body", represented by a block in the center of the candlestick. This replaces the open and close tick on the bar. If the body is filled in, or black – it shows that the candle closed lower than the open price. Conversely, if the middle or body is hollow or white, it shows that the candle closed higher than the open. You will also see where some traders color their candles. While the sky is the limit for color choices, normally green will represent gains and red represent losses.




Let’s take a look at a candle chart, colored with the green and red candles:

As you can see, there are a lot more green candles than red. Right away, you know that buying has been strong. This is further confirmed since many of the green candles are longer as well, showing a wide range. Notice how the red candles are sporadic, this shows that there is little selling pressure. There was a definite turn in the trend around the 23rd of January. Can you see it? It is represented by the change from mainly red, to mainly green candles.
