Simple setup, initiate a short when the support is breached.
We have a very strong decline after completing what looks like an expanding ending diagonal triangle in the 4h/daily charts.
If price moves below the support level outlined in the chart, it will accelerate down, probably moving 430+ pips to the downside.
As a bonus, crude oil seems to be moving up, while Nikkei falls, effectively boosting this trade, correlation wise.
Will update with my entry and scale ins.
Good luck,
Ivan.
