Nikkei 225 is stuck in a box. We need to see a move out of it before we can start looking into any further directional move. A break through the upper side, may lead to some higher areas, like the 21875 zone, or even the 22225 barrier.
On the downside, a break through the lower side of the range could push the index further down. But the downside might get limited near the upside line. If that upside line gets broken, then we may start targeting even lower areas.
