I was looking at a 15 minute chart of ES and counting the volume and noticed that at a certain interval there was a change in direction. I did this for enough days and in different months to discard any suspicion of coincidence. The turning points were not always steep, but they were there. I guess it works on other symbols too. Just a hint for all the traders out there. Not divulging the exact volume interval here. Any secret you got to share?? Just leave a hint, like I did.
