When you trade forex, you're effectively borrowing the first currency in the pair to buy or sell the second currency. With a US$5-trillion-a-day market, the liquidity is so deep that liquidity providers—the big banks, basically—allow you to trade with leverage. To trade with leverage, you simply set aside the required margin for your trade size. If you're trading 200:1 leverage, for example, you can trade £2,000 in the market while only setting aside £10 in margin in your trading account. For 50:1 leverage, the same trade size would still only require about £40 in margin. This gives you much more exposure, while keeping your capital investment down.
Forex banks, ECNs, and prime brokers offer NDF contracts, which are derivatives that have no real deliver-ability. NDFs are popular for currencies with restrictions such as the Argentinian peso. In fact, a forex hedger can only hedge such risks with NDFs, as currencies such as the Argentinian peso cannot be traded on open markets like major currencies.[80]

One way to deal with the foreign exchange risk is to engage in a forward transaction. In this transaction, money does not actually change hands until some agreed upon future date. A buyer and seller agree on an exchange rate for any date in the future, and the transaction occurs on that date, regardless of what the market rates are then. The duration of the trade can be one day, a few days, months or years. Usually the date is decided by both parties. Then the forward contract is negotiated and agreed upon by both parties.
Hi everyone, AUDUSD was strong bearish in 2018 and we were selling AUDUSD right from the top when it was at the 0.81. The bearish fall was very nice and we enjoyed that fall very well. Now its time to look for it to go back up and hit the 0.81 area again. . So we have enough price action on lower time frame for reversal. Which means we should look for long on...
Another possible source of confusion is that GMT is always just that, summer, winter and fall. Eastern time, however, comes in two flavors: Eastern Standard Time (EST) and Eastern Daylight Time. Since the agreed-upon reference time worldwide is actually GMT, which has no Greenwich Mean Daylight Savings Time, this means that a New York trader who chooses to reference Eastern time rather than GMT, must keep in mind that during Daylight Savings Time in New York, the trading hours shift by an hour because the GMT reference time, needless to say, does not shift.
For trading purposes, the first currency listed in the pair is always the directional currency on a forex price chart. If you pull up a chart of the EUR/USD, and the price is moving higher, it means the EUR is moving higher relative to the USD. If the price on the chart is falling, then the EUR is declining in value relative to the USD. The attached chart shows this. 
An exchange rate can suffer rapid changes, sometimes several times a second, so there’s a lot of action going on 24 hours a day, 5 days a week. In general, the currency exchange rate reflects the health of an economy in comparison to others. If the economies of the Eurozone are doing better than the US economy, the euro will go up compared to the dollar (EUR/USD ↑) and vice-versa.
There are actually three ways that institutions, corporations and individuals trade forex: the spot market, the forwards market and the futures market. The forex trading in the spot market always has been the largest market because it is the "underlying" real asset that the forwards and futures markets are based on. In the past, the futures market was the most popular venue for traders because it was available to individual investors for a longer period of time. However, with the advent of electronic trading and numerous forex brokers, the spot market has witnessed a huge surge in activity and now surpasses the futures market as the preferred trading market for individual investors and speculators. When people refer to the forex market, they usually are referring to the spot market. The forwards and futures markets tend to be more popular with companies that need to hedge their foreign exchange risks out to a specific date in the future.
