Along a range of historical price values, this script draws a line from each previous price to the current price and moves the line so it begins at the current price instead of ending at it. The resulting polar array of lines which projects potential price trajectories into the future in a pattern which resembles a sneeze can be used as a visual aid to help anticipate future price direction. Sinus pressure can be adjusted to consider a lesser or greater historical range than the default which is 100 bars and the sneeze trajectory length will reflect the adjustments. I could not get the sneeze lines to be the exact lengths they should be due to type casting difficulties when scaling future delta x to be the same length as past delta x, but they're close enough.
