The mini magnets are found by using the new order prints tools. We are testing them as I write this. Currently we are calling them in the Elite room for people as we go. Soon people will have the same tools and can spot their own.
The auto trail that I use with ninja is their ATM from chart trader (Automatic Trade Management). Currently with Nadex spreads the only way to trail a stop is manually with the Apex stop trigger. Soon their will be automatically trailing stop available and is in the works for Nadex, through the Apex scanner.
