Once you have down loaded Meta Trader 4 ( highly recommended ) or some other forex trading chart, I would suggest learning about different candles that you will see on the charts, these can warn you of many different things that are most probably about to change on the time frame you are looking at and knowing this will help you decide on entering a trade or not, rather than just jumping into a trade and hoping for the best ( Gambling ). Leaning to trade certain candles and candle patterns can prove to be quite financially rewarding, but this can take a bit of time so once again ensure you are using your Demo account.
Also check out the other tools that are available on Meta Trader 4 such as Bollinger Bands, RSI, Stochastic Oscillator, MACD, Moving Averages, to name but a few, these tools can be used separately or together as part of a strategy that you may wish to use.
Put some time into learning about items mentioned above and you wont regret it as this will help you grow as a trader, and the same with the strategy you choose, understand it and its rules.
Like most things in life, if it doesn’t come naturally you will have to educate yourself to be good at it.
