When you look at a market, equity, or trading instrument, you typically first look to see if the market is trending up or down. You can make money on either direction, but you want to be sure of the direction before going forward and that is where balance of power comes in.
Understanding which is greater, bears or the bulls can give you an edge on your investing.

Adding balance of power can help you to see the flow of power to the upside or downside, giving you a more confirmed opinion.
Just like an tool, these are not one hundred percent and should be used with a little bit of reserve. For technical trading, this tool will work better because it will help to show you insight that fundamental analysis may not. Another aspect to keep in mind is the flow of funds from institutional investors, because they drive much of the volume you see on the popular stocks.

Be sure to test this on a demo account first because you have to ensure it will fit with your current setup and why risk a live account when you can test it for free.

If you ever get stuck, reach out to your investing professional and they can certainly help point you in the right direction with understanding the charting tool. Understanding the flow of funds and balance of power will open a whole new world into your trading and investing mindset.
