Your chart isn't SCALED right. Those arcs are the most precise method of determining a point there is, especially in conjunction with right diagonals. Gann always considered SCALE of utmost importance. A circle on a properly scaled chart would be an ellipse on an improperly scaled chart. Check out my chart on GBPUSD to see what I mean. It's not enough to draw circle or even have the right ratios. The market's are all geometric and have specific scaling for each symbol OR time level... daily, 240, 60 etc. Just type the symbol in search in my published.
