[George Bayer (1940): Stock and Commodity Traders´ Hand-Book of Trend Determination. Carmel, California; p. 13]MARS-MERCURY SPEED DIFFERENTIAL OF 59 MINUTESWe use the geocentric longitudinal speed of Mars and Mercury ... Each time Mars reaches a point that is 59 minutes apart from the Mercury speed we are due for a down trend of about three days duration. It does not matter whether we have been going upward in the trend before. We might have been going downward and upon reaching this differential, we are heading for further down.
