Quote from reiehaxm:
While watching price action, pressing the reverse button is many times my most profitable trades. Filling my screen with more stuff costs money. Obviously if I wasn't scalping and had 30 seconds to think about a trade, switching between FAS & FAZ would work just fine.
I'm not a scalper, but I agree when going for a small move and watching price action to determine an exit, 5 seconds is often the difference between a profitable trade and a break even trade.
