Depends on your strategy. If you are doing scalping, then you can't rely on your dial up. If you do trending, then you can. I use trending strategy, so I'm okay even if using GPRS.

This order would look something like this:
Buy: EUR put/USD call
Strike price: 1.2900
Expiration: 2 March 2004
Premium: 10 USD pips
Cash (spot) reference: 1.3000

Say the new reports come out and the EUR/USD pair falls to 1.2850--you decide to exercise your option, and the result gives you 40 USD pips profit (1.2900 – 1.2850 – 0.0010).

You place a trade in GBP/USD. Let's say you decide to short the pair at 1.7500 with a 1.7600 stop and a target of 1.7300. At first, the trade is doing well. The price moves in your direction, as GBP/USD first drops to 1.7400, then to 1.7360 and begins to approach 1.7300. At 1.7320, the GBP/USD decline slows and starts to turn back up. Price is now 1.7340, then 1.7360, then 1.7370. But you remain calm. You are seeking a 2:1 reward to risk. Unfortunately, the turn in the GBP/USD has picked up steam; before you know it, the pair not only climbs back to your entry level but then swiftly rises higher and stops you at 1.7600.

You just let a 180-point profit turn into a 100-point loss

Profit both way in forex means:

In Stock market, most people only make money if the stock price goes up. Example: Stock #1234 (Lyn.net) Rm1.50 shot up to Rm2.50.
That's a unrealize profit of Rm1.00 not including the commission fee to broker. This is known as BUY/ LONG in forex.

If that stock #1234 suddenly drop from Rm1.50 to Rm0.50 , you will lose money in Stock market if you sell your position. Unless you do SHORTING in stock market, which is to borrow the stock now from your broker and sell it back when the price roses back. This SHORTING is different from Shorting in Forex.

To summarize: In stock market, you profit when the stock goes up only. But in forex trading, you are make money whether the stock(Currency Pair) goes up or down. To make money if the currency pair goes up, just Long(BUY) , to make money if the currency pair goes down, just Short(SELL).

FX is more fun than stock market
