This section metformin er 500mg side effects will be short, but it is vital as there are plenty of new terms that will be mentioned during this course and on the forum itself. When entering a new field of study, there is always going to be terms that you are not familiar with. By listing some of the most commons ones here, hopefully your journey will be much smoother.
A "pip" is the metformin hcl side effects smallest measure of movement that a currency pair can travel. (The name is short for "Percentage in Point".) For example, if you see that the quote for the British Pound moves from 1.4013 to 1.4014, it has risen 1 pip. While this example has 4 decimals at the end, note that many brokers are switching to 5 decimal points in order to represent 1/10 pips. If the previous example were traded at one of these brokers, the quote would rise from 1.40130 to 1.40140 – noting that the last decimal is not a pip, but merely a tenth of one.
All currencies are traded in pairs. In other words – you are comparing the value of one currency against another. (You already are familiar with this concept, even if you don’t know it. When buying IBM stock, you are simply hoping that the stock rises in value against the dollar, and that you get more of those dollars when you sell. It’s the same thing with the Swiss franc or any other currency.) As such, there are a lot of symbols that you might see on the open market, but there are only a limited amount of them that are traded actively. For example, major economies are certainly heavily traded, but smaller nations tend to have very thin marketplaces. There actually is a market for trading the Chilean Peso against the Norwegian Krone, but is is generally only used by companies doing business between the two countries. Keeping this in mind, this is a short list of the most common ones you are likely to see:

| USD | US Dollar |
| GBP | British Pound |
| EUR | Euro |
| CAD | Canadian Dollar |
| JPY | Japanese Yen |
| AUD | Australian Dollar |
| CHF | Swiss Franc |
| NZD | New Zealand Dollar |
Using the eight most widely traded currencies listed above, we can begin to understand how pairs are assembled. By taking the two symbols and separating them by a forward slash (/), we are creating the symbols that are used by traders around the world. It is theoretically possible to trade these symbols in any order, but a majority of FX brokers will only offer them in certain orders. This creates a consistency in pricing that makes trading much easier. As an example, the US dollar against the Japanese yen is almost always listed as USD/JPY, not the other way around. In fact, most of the time you are trading JPY/USD is to reconvert your profits from a Japanese stock you might own back into US dollars. After all, the stock in Japan are traded in yen! Confused yet? Don’t be. Here is a list of the common currencies as you will see them listed 99% of the time:

| USD/JPY | US Dollar against the Japanese Yen |
| USD/CAD | US Dollar against the Canadian Dollar |
| USD/CHF | US Dollar against the Swiss Franc |
| EUR/USD | Euro against the US Dollar |
| GBP/USD | British Pound against the US Dollar |
| AUD/USD | Australian Dollar against the US Dollar |
| NZD/USD | New Zealand Dollar against the US Dollar |
There are other combinations, such as the AUD/CHF, and the NZD/CHF, but these aren’t very heavily traded. These markets tend to be a little more difficult for the newer trader to get a grasp on, so we will live the list at this for now.
Two terms that you will hear over and over are the terms "bid" and "ask". If you are familiar with other markets, you will understand this right away. If you are not experienced in trading at all, these two terms represent the "cost" of trading on the open market. (Your broker, depending on the business model, might add to it as well.)
Essentially, the "ask" price is what the sellers of a currency are willing to sell it for. As an example, the AUD/USD might currently have an ask price of 1.0850, as it is the lowest price that a seller is offering at this moment. The "bid" price is what the current highest price the buyers are willing to pay. The distance between the two is known as the "spread". There is almost always a spread, except in very heavily traded markets that are on an ECN broker. The most common business model for an FX broker is to not charge a commission, but to collect the "spread" as their fee for placing the order. So let’s take a look at a quote:
AUD/USD 1.0846/1.0850
This quote says that the "bid" or highest price buyers are willing to pay at the moment for the Australian dollar is 1.0846 US dollars. In other words, if you wanted to sell the Aussie dollar, you would get 1.0846 US dollars for every one sold. If you did this, you would be anticipating that the value of the Aussie would continue to fall, and that you could buy back your position at a much lower rate – collecting the extra AUD for your trouble. 
The same quote says that the "ask" or lowest price sellers are willing to part with the Australian dollar at the moment is 1.0850 US dollars. So if you wanted to buy the Aussie dollar, you will pay 1.0850 US dollars for each one. Doing this, you are anticipating that the value of the Aussie will rise over time. You are hoping to square out your position at a much higher rate, collecting more USD than what you started with when you do so.
It should be noted that the "spread" was 4 pips. That went to the broker, no matter end result of your trade. If you are using an ECN, it is a little different as they typically will charge a commission on top of an extremely low spread. (The spread might have been 1 pip as an example.) Many of the market maker brokers out there will actually add a little bit to the spread in order to make their profit. (Or even take the other side of your order, trading against you in the process.) The ECN doesn’t do anything more than facilitate your order – matching you to another trader. They make their money on the commission, and have no interest in the order beyond that.
Now that we hopefully have cleared that up – lets move along.
