NIOX double bottom pattern firms up as stopping volume around 56NIOX Group PlcLSE_DLY:NIOXStockso_SimpleA double bottom style setup that grabbed my attention this week. The bullish move I annotated came with higher relative volume behind it, and now the price is back near the supported low around 56p. The most recent session gapped up on the open, rejected to the downside and closed with over double the average volume. Classic stopping volume behaviour at a known support level. The volume profile on the right tells an interesting story too. There is a distinct concentration of volume traded between 54p and 61p. I think this is the footprint of a larger institutional buyer building a position over time. These players simply cannot fill an order at a single price point as there is rarely enough stock available at one level, so you see the accumulation spread across a range instead. Price target: 70p Potential reward: 19%
