Sometimes trading is as simple as knowing in which time frame you want to work (depends how much time are you able to expend)
Eventhoughtimeframes differ between what kind of asset are you trading with, you can basically divide it in 3 groups: long term, middle term, and short term.
Usually market has a zig zag behavour, so when its going uo (bullish trend) it doens't go in a straight line. Those corrections can be classified as middle or short term.
As you can see in the pair EUR/USD, there is a bearish long term trend, so basically if you have no time to expend trading you can short it and forget bout it. If you wanted to trade in a monthly timeframe, you could open a long possition and wait. In further post i'm talking about resistences and supports and how you can use them as stop-loss or take profit areas.
If you have enough time to trade between weeks, you could open a short possition and wait for other indicators to show a trend change.
Hopefully this can help begginers in the trading world. I'm going to be posting tutorials like this each day (basics in trading)
