All time frames are made for traders to get on the forex market. Some traders use a higher time frame while some use a lower time frame. Many use a time frame for different reasons but traders only have to understand that the higher the time frame the higher the profit.
I found that I found that it depends on two time frames for trading that are 15m and 1H but in this case I just follow the trend D1 means I open as a trade only in the direction of the trend that is on D1. This gives me a better win ratio. There are many things that are measured in this matter and I personally believe that at first we chose the strategy then the time frame!
