It's an experiment. I find NF too volatile, so I set my SL and target based on these. One of my screens is full with NF charts, only half of the other screen used to track international markets.
But it is turning out to be successful now, I traded short and long both today based on this - 6 trades : 1 breakeven/scratch, 5 successful (as per my standards, some seniors here have different standards to call a trade successful).
