CNA Tight Bars Hint at AccumulationCentrica plcLSE_DLY:CNAStockso_SimpleYellow lines are usually where I mark major support and resistance levels, and this one was drawn nearly two years ago from an old gap. Interestingly, price has been flirting along this line for over a month now, with the range tightening, and a sudden volume spike last Friday could mean this level matters to someone. Telling accumulation from distribution off price alone is tough, but here is my rough rule of thumb. Tighter bars tend to mean accumulation, supply has dried up so it doesn’t take much to shift price. Distribution often shows up wider, with market makers hunting liquidity as they try to offload size into anyone still buying. It’s not gospel though. Springs and shakeouts inside accumulation can throw up a nasty wide bar too, that’s the whole point, scare the weak hands out before accumulating more. Just a rough point of view, not an exact science.
