What is noise? Noise is when the market is moving up and down in short moves. This can be seen in smaller time frames very easily. For example, on the 5-minute time frame you will see the market move in 10-15 pip cycles, then it moves for 20-25 in one direction or another and starts the 10-15 cycles again.
When you look at a larger time frame you will see the market moving in a good trending pattern. There is a good direction with few retracement moves on each individual candle. When you take the same time frame and look on a 5 minute chart you can see all of the up and down movement.
One cause of noise is NEWS. The TV, magazines, and other articles or sources of information cause some of the noise on the smaller time frames, with most of this information being old when it is released. Another cause of noise is major economic changes or announcements. They do not last long or they will change the overall trend completely. Either way it will cause choppy movement on the smaller time frames which is just noise. Another source of noise is listening to hot tips from whatever source it may come from. This may not move the market but it clouds your thinking. When you get a choppy market and a clouded mind you need to sit back and remember where you are going and get back to basics. Sometimes it is good to just get away from the market for a few days, even during trading hours, and clear your thinking. You will be amazed what a little break can do for you.
A good way to avoid noise is to watch and see what your indicators are telling you. Use the trend on the larger time frames and select your entries on the smaller time frames. The smaller time frames go against the trend then return and align themselves with the larger trend. This is the time to look for an entry into the market going in the direction of the larger time frame.
In conclusion, make your own decisions and trade with the long-term trend. You do not have to listen to all the news to know which way the market is going. Let the market tell you what it is going to do.
