lately, I've been getting heavy into the non-linear charting using fib spirals and arcs. It's great stuff. But yeah, just another diagnostic tool to find confluence with price action.
Hope that helps. The trader that really gave me the a-ha about using fib spirals is named BitComRat. Check his charts out. :)
so far I've tried many different price-bar ratios on the spiral, including pi, fib numbers and ratios, but none of these ratios can consistently produce well aligning spirals across time and assets. I'll try your 3++ rule and see how it goes.
Thanks a lot, please keep sharing your beautiful charts :P
