If your going to trade purely off the charts, my advice would be to trade the higher time frames, 4h and daily. and have more of a swing trading approach (assuming your not trading stocks). Don't try to day trade with charts alone.I think it's very hard to learn fundamental analysis because I just got started with Forex. Also, I need to use 1h chart because most of the day, I can't check the chart very often. Is it good idea to use 1h chart based on 90% technical analysis?
