Classic floor-trader pivots from the last completed daily bar. Highlighted pills are the levels bracketing the current price.
The range is measured volatility (ATR over the horizon), not a target — a wider band means a more volatile asset, not a stronger view. The direction is the indicator tally above. Every forecast is recorded when made and scored against the real price when it comes due, including the wrong ones. Not a recommendation, and not a fatwa.

Research only, not the primary verdict above — SEC EDGAR (the source for the main in-house research card, if shown) has no data for this symbol, so this is computed from a real, country-specific filing instead. Business-activity screening isn't part of this check.
