When Mercury goes retrograde, mistakes, misunderstandings, problems in communication and transportation are likely. Do not sign contracts, nor buy new items, nor begin new projects. It is an excellent time to plan, research, and prepare for something that will happen later.
Don’t make any important moves when Mercury is retrograde. Nothing will be settled successfully for the future during these periods anyway – you will find it nearly impossible to nail down a plan. During a retrograde period, it is hard to get decisions from others. Even if a decision is made, it will be subject to change, either just after Mercury turns to direct motion or much later.
Mercury retrograde periods would not be good times to do anything involving communications, such as launch a magazine, website, or an advertising or publicity campaign. It is a poor time to launch any new projects, even if they are not related to the communications industries.
Similarly, a retrograde period is not a good time to sign any contracts or even to shake hands on any new agreements. Avoid closing on a house during this time nor sign a lease. Verbal agreements are considered the same as written ones. The environment will be quite fluid and changeable, no matter what you are told or what you think.
