Trading the Forex market is like nothing else. Thanks to leverage up to 2000:1 with some brokers you have access to millions of dollars with thousands of dollars only.
With this leverage if you have a winning portfolio, earnings of 100% a month and even more are possible and quite real.
To have a winning portfolio you need:
1. Invest in different currencies. Money invested in just one currency is good when things go well, but if they go bad your losses are far greater than if you diversified your portfolio.
2. Hedge currencies, which means that if you want to long the EUR/USD also invest in the GBP/USD so if the euro fails, the pound might do well and you reduce the risk.
3. Always use a stop loss because the markets can go crazy anytime without any warning and you need to cut the losses. The stop loss should have at most 10 pips and the take profit should have at least 15 pips so you have a reward ratio of 1.5.
This is how I have a winning portfolio on the Forex market. Some traders invest everything they have in just one currency pair and do well. Other traders also invest but in multiple pair and also so well. You should really try with the demos first and see which strategy suits you the best.
