The most overlooked but powerful indicator makes you see the markets for what they are.
You will see how much the markets move on average per day. This is fantastic info if you are an intraday trader and want to set your take profit within the average range, so you have as high a probability as possible of reaching your take profit today.
You can also trade reversals from ADR high and low. Very often the price changes direction back into the middle of the ADR high and low, at around 50%.
