My Friend
I am using Trend and Reversals for my trades.
The Fundamentals do play a large part of my trading, but if we are in a staunch uptrend then i will not play against it.
If I feel that the news is negative against e.g. USD then i will definately not buy into that currency.
I only Buy/Sell when it is almost certain that i will score.
I have sat with Open Trades in the negative for 6+ days, but there is normally a respite where you can close them at Breakeven or for a minimul loss.
