Medium term Trend under Threat

I am already short here, when i took the trade I pointed out that a medium trendline was below and that it was the main concern regarding the trade. Price action has brought the pair to the trendline, a break here would give us potential for a significant downward move.
I am currently short the NZD v GBP, AUD and JPY. They are all well in the money, the GBP trade is approaching its target of 2400 pips and the AUD stands at 900 pips. images attached
