OK I get your point but point being Knifeys don't come across every day, so when they do pop up they are worth watching, to see how they can play out, opening minutes and that hour is the volatility that DTers can take to their advantage. But I only mentioned screen acreage to watch, its like DTing normally. Watching what happens is invaluable knowledge, when you feel ready trade small. Never jump straight in, these are the riskiest of plays and the quickest way one could blow up their a/c if they don't position size it.
Best practice is being able to read a reversal FFF.
