My question is fairly simple. I have been using the PP from 5pm since I started. I had the impression these were the most commonly used and thus the most respected by the market. It seemed logical to me that these would be the best points because they would include all the data from the last days sessions. Meaning the same day for all three markets. I recently had someone tell me they use PP from the London session and another who uses the Asian session. What are the most commonly used lines? What time should the points be calculated at?
