Restriking My Nikkei Call Spreads After Rally

Nikkei has rallied to my upper strike of the original trade of 17000. Even though the Yen has not really moved, I believe most of this move is on expectation of BOJ as well as Government stimulus. Either can provide additional upside to the trade from current levels. . So, i up restriking the trade to be long the 17000/19000 spread.
