Vendors selling something should back up their pitch with real time trades to have credibility. Others need not.
posting before the trade or at the time of the trade ensures truth. it shows what can be done with the markets. that is, it may point someone to a possible idea to study. example: I have posted for awhile now that the last week of next month is a time to look for turns in direction in financials. If such comes to pass, a newbie might take up the study of time and find methods unique to himself.
The stocks look like they want to take a stab down to get the bears excited, i agree. like to see if aapl can hit 120 or so.
