If anyone can swing 2 to 3 OR 3 to 4 back and forth consistently, I'm all for it. Range trading is great but one has to have significant free cash while trades are being settled.
Just don't pretend to confuse NGBL with a real company. It's just a trading vehicle for some. As long as there is a market and the price moves in this range it's great.
But when the range shifts down and you get caught with a bunch of out of money orders that is where one can really feel the pain. IF it ever happens.
