Surprisingly the price action acceleration don't happens at the maximum acceleration of Mars speed but after it reached the maxima around 0.75 to 0.76 degrees per day and stabilise around 0.7 for subsequent slow decrease through the course of few months to 0.62 - 0.58 daily speed range, during all this period the price action is strong. Once the Mars speed cross the 0.50 and goes into negative (in retrograde motion) the price suffers a congestion.
Note: The Mars speed indicator is based on an ephemeris array that covers years 2010 to 2030, prior or after this years the speed is not available, this daily ephemeris are based on UTC time so in order to align properly with the price bars times you should set UTC as your chart timezone.
