choosing the right time period depends on the strategy we use, and the type of trader. if you want scalping, most traders choose smaller time periods like M1 and M5 cus they take short trades and small pip targets. for the use of a long-term H1 period and a larger time period and take a very high pips target. and absolutely for me, I personally really think that it depends on the trading strategy that we use today. For aggressive trading strategies, we must use a short-term time frame and vice versa. But it also depends on current market price fluctuations and economic conditions to produce better profits.
