* - Backtesting and a strong Technical Analysis support must be needed. Here is a good example of that:

* - You must create a EA (a software) to avoid requotes and to enter at the right time.
* - Don't trade news has little or none influence on the market. That is news that affects the market in 10 to 50 pips are very difficult to make money with due to spreads.
* - Trade big news those that can move the market more than 100 pips. In order to avoid wide spreads you must trade long term movements.
* - Be sure you have the right source of information. You might want to check Reuters, DailyFX, and some blog about news:

* - Find a good broker with a great bank support which would allow the broker to fix tight spreads. These brokers are difficult to find but if you check Oanda, Tradeview Forex, ACM, and a few more, you could find something good.
If any of these issues are missing you might stay out of the market during a news release.
