A good question, but if you want to understand forex, then 1 hour a day is not enough.If you still have 1 hour and you want to spend it on forex profitably, then I would choose currencies with good volatility and trade during a particular session. For example, the JPY session in my time zone starts at night, USD in the morning and noon. Thus, you can choose a more convenient option.Use the schedule for 5 minutes, 15 minutes. If you can afford to keep deals for more than one day, then you can open a deal today and spend an hour on careful analysis, and tomorrow close the deal and open a new one. So you can use H4 and D1
