I don't have access to the NZ stock market but looks like a massive bubble. Trying to guess the top here is a fun project.
Currently the market is smiling at us. - Double top with a lower high.
If the US stock market runs out of steam in the short term I believe that it could pop the NZ stock bubble.
idea would be to short with a stop sell order once the price drops below the recent weekly reversal candle, because price action is suggesting we are getting rejected from moving any higher. If price moves higher than the previous week then idea invalidated.
