The lower ceiling 0.6150 is subject to final prices of NZDUSD and USDCHF at their lower ceilings. It should be noted that CHF may carry NZD at lower ceilings of NZDUSD by Fed or at lower ceiling of USDCHF by SNB.
Comment:
I also trade NZDCHF by multiple tranches from interdays high (upper price trend channel) to interdays low (lower price trend channel)
