btw you can actually follow this HFT algo on 1sec & 1min charts for scalp trading with just https://chart.kiyotaka.ai/ - using heatmaps - CVDs Essentially what happened here on 1sec & 1min was clear absorption into 110K bid liquidity - passive buyer stepped in - HFT algo got filled & the passive buyer was the signal for the algo to chase price higher Often these algos are the market in between areas of market liquidity (demand & supply)
