I reckon every day N - the market makers are trying to find - via their super computers ways to confuse and trick the rest of the markets - via new correlations and using HFT to change things in seconds - never mind minutes
What they cannot get away with changing is the PA of HH and HL etc for rises and the levels that provide supply and demand or S & R etc
They can breach them by 2 -4 pips to set bots off on wrong moves - but certain things they cannot trick etc
The more money involved - the more important to come up with new ways around the traditional ways of the past
Nothing surprises me today - and its up to us as retail traders to really understand all the tricks and method they use - so that we can join in on the back of their moves whilst maybe 80% of the market gets screwed
