Planets / asteroids speed change visualizations

[citlacom]

Similar to the longitude distance planets plots would be interesting to visualise the speed change cycles from all planets / asteroids considering that many financial astrologers suggest that retrograde motion and stationary phase is very relevant to trend changes in market prices. One of the most relevant traders that advised to consider the speed changes in planets was the mythical trader W. D. Gann. as could be noted in him Wikipedia bio https://en.wikipedia.org/wiki/William_Delbert_Gann
