Multiple Time Frame Analysis
Multiple Time Frame Analysis is the technique of analyzing several time frames of the same asset before entering a trade. This type of analysis is best done using a top-down approach, i.e. starting at a higher time frame and working your way down, via several lower time frames, until the execution time frame is reached where a trade could be entered. Traders who use this technique usually look at 3 or 4 different time frames to identify the general trend and find the best entries. They minimize their risk and improve the odds of success simply by taking the bigger picture into account. It can easily be combined with any trading strategy.
Time frames are usually several times apart. For example a day trader who trades hourly charts, could analyse the weekly (high time frame), the daily (7 times smaller), the 4 hour (6 times smaller) and finally the hourly time frame (execution time frame, 4 times smaller). TradingView has a chart layout feature with multiple charts per layout, so you can analyse an asset on multiple time frames under one tab in your browser.[1]
Multiple Time Frame Analysis，这个词似乎没有一个权威的译名，但我更倾向称它为“多时间尺度分析”。
Timeframe 并无定式，可以是 M15、H1、H2、D1+，总之就是要从多个（三个以上）时间尺度来观察价格变动，只有在多个时间尺度下同时确认后方才发起交易。通俗来讲就是通过获取更多的信息来作出更稳健的决策，以期提升成功率。客观上也减少了总的交易次数[2]。而且 MTFA 便于跟其他的交易策略结合。
常见的 timeframe：
M5/M15、H1、H4
M5、M15、H1
