The goal was to see a move up into the 14400 area to then see what would happen. When marking up weekly highs and weekly lows, you get a better sense on what the market wants to target. In this case, it targeted the high one last time before aggressively going for the weekly low. It didn't quite reach the weekly low during the week's trading session but as soon as the market opened up on Sunday, it gapped straight down to it.
