Yes dear readers we are going to dip our toe into the waters of the fantastical other realms, in this case astrology! Whether or not you believe it or not, why not throw some salt over your shoulder and mark the dates below on your calendar for this year? These are the dates that Mercury goes into retrograde. These periods mark a time when stuff ruled by Mercury can go awry.
'SRx' is' retrograde'. 'SD' is 'station direct' where the planet moves from retrograde to forward motion. Here's a nice summary of the effects of a Mercury retrograde:
Mercury retrograde gives rise to personal misunderstandings; flawed, disrupted, or delayed communications, negotiations and trade; glitches and breakdowns with phones, computers, cars, buses, and trains. And all of these problems usually arise because some crucial piece of information, or component, has gone astray or awry.

Tillet also notes:
In general, Mercury rules thinking and perception, processing and disseminating information and all means of communication, commerce, education and transportation. By extension, Mercury rules people who work in these areas, especially people who work with their minds or their wits: writers and orators, commentators and critics, gossips and spin doctors, teachers, travelers, tricksters and thieves.Because of the 'tricksters' and 'thieves' inclusion above, this retrograde fully embraces the market! Supposedly this is also a time when technical analysis, specifically supports, signals etc fail.
