FTSE 100 (1H) – Sharp Sell-Off Tests Key SupportUK 100CAPITALCOM:UK100Sir_Stylez_The FTSE 100 has experienced a significant intraday decline after failing to sustain trading above the 10,600 resistance zone. The strong bearish impulse has erased recent gains and pushed price back toward a major support area around 10,430–10,450, where buyers are attempting to stabilize the market. Technical Analysis The chart shows that price previously respected an ascending channel before breaking higher and establishing a series of Higher Highs (HH) and Higher Lows (HL). However, repeated rejection near 10,680–10,700 exhausted bullish momentum. The recent bearish candle has broken through multiple intraday support levels, shifting the short-term bias in favor of sellers. Price is now testing a historical demand zone around 10,430, making this an important decision point. While the broader medium-term trend remains constructive, the immediate momentum is bearish until buyers reclaim lost resistance.
