Multiple time frame analysis is simply the process of looking at the same pair and the same price but on different time frames.
Remember, a pair exists on several time frames – the monthly, weekly, daily, the hourly, the 15-minute, heck, even the 1-minute!
This means that different forex traders can have their different opinions on how a pair is trading and both can be completely correct.
Practical Use: Technical analysts use different timeframes to better understand the sentiment of a chart on long and short basis.
