It’s known that the higher the timeframe you are using, the more reliable the price action is.
The price action that you see on the weekly time frame holds more weight than the price action that you see on the daily chart. The price that you see on the daily chart holds more weight than the price action that you see on the 4-hour chart and so on…
But, if the price is showing you that it wants to go in the same direction on multiple time frames, the chance of the price then actually going in that direction is a lot higher compared to just one timeframe.
Trading is a game of probability. And we want to take trades that have the highest chance of going in the direction that we are trading. Using multiple timeframe confluence raises the probability of our trade going in the desired direction.
