Good initial push so far as we test long-term trendline and short-term EMAs.
The goal for today's D1 close would be to hold (close) above the previous ~1660 support line or perhaps the new tentative line at 1670; this could also be noted as 200EMA.
In doing so we would likely prevent a bearish piercing scenario while providing a solid setup for continuation towards 1800-1900.
The purple zone is now considered a volatile zone if the above fails.
