It's very handy to be able, through reading and listening to the goings on in the markets, to have a higher probability of what the banks are buying or selling that day.
There is a great deal to be gained from fundamental analysis, I'm not talking hours of research, just get the bones of what's happening, and add this to your method of trading.
There has been a number of times, my method has indicated Trend is Up, but by reading about the actual happening regarding the currency I Judge the trend for that day will be down, not saying I am right all the time, but my point is without that knowledge I would be trading with less in my bag of tools.
You can also find out which currency is strong, for an example, US-EUR, base currency is weak and falling, is that because the dollar is weak or is it due to the EUR being very strong, or in deed both weak and strong, you just don't know these things without the fundamentals.
We all hear so many times how 94% of all traders fail, we also hear that all the fundamentals are absorbed into the markets, and are told there isn't a need for learning the other side (fundamentals), however watch your calendar and don't trade around important fundamental declarations, wait for awhile after the markets have settled down absorbed the news, then away you go, but I ask you, what has just happened ?
Perhaps you see the dollar spike up 100 pips against the Euro, but why, and will it come back again, has the news something to do with weakening the EUR, or strengthening the Dollar, there is allot to be got, allow 20 mins a day reading about the fundamentals regarding the currency your trading that day, do this for one week, you will take that extra knowledge and without even thinking about it add this to your technical analysis. It's not hard and it's habit forming so self effort won't even be required.
I must add I am not nor will I ever be fanatical regarding fundamental analysis, I regard myself as a Technical Trader, but I would be daft to ignore the fundamentals.
Have a Great day
