ES - I have a couple very interesting charts that I felt deserved it's own entry.
Here is the 15-min ES chart up to mid-day Wednesday. You can see how the Gann levels contained this movements perfectly (almost to the tick!). After a return to the 50% line (270°, half of the 540° move up). After that, I found it interesting that the movements kept halving on the way up... 90 to 45 to 22.5. The end of that series (912.75) just happens to be yesterday's close! How can that be a coincidence? What if we did this math (right after yesterday's close) and saw all this movement prior? What if we wrote some software to help identify these possible scenarios for us? Still learning...

After the above series of moves, we popped to up to 917.75 daily level and fell hard. See chart below. I am admittedly still learning how to use these Gann levels. I am learning what pivots to take the measurement from, whether to use the high/low or close of the bar, and the factor to use. However, I can't deny how amazingly accurate they are, if used correctly. Thus, I am focusing hard on using them and learning from them (and updating and improving my tool that generates them). You can see today's low was dead on at the 450° level (360+90) and our high was at 540° (360+180).
