Picking the correct time frame for your trading goal is extremely important. I see too many beginner traders making huge mistakes when picking charting time frames. If you are day trading, you should be using much shorter time frames than if you are buying to hold for a long time. It all comes down to your perspective on the chart. A longer time frame chart is going to have more information but it is going to be less granular.
The video above breaks down exactly how you should set up your chart so that you can achieve the trading goals you have set for yourself.
