Note the grey . This is just something I wanted to bring up because it came about when I was looking at this USDOLLAR chart. Previously we had a candle into a down move (on the left of the chart). Note that price on the candle where the arrow points is exactly where the accumulation candle opened previously. This means that there were still a few buyers at that level where that previous candle was (or at least some people wanting to buy at that level). Now note the pink candle. This is a 4H mitigation orderblock, where price has previously been into this level, broken through and has come back to this level to be again.
