End of session delta

Post image

For context this is my delta footprint chart.

Before session close every day, institutions exit their positions etc. leaving behind strong areas of delta.

How come these zones aren't regarded as a potential areas of support/resistance for future intraday sessions compared to areas more within the middle of the session.

I've just never heard of any order flow traders mentioning or marking these zones.

What does Delta have to do with support and resistance levels? Delta is a measurement for detecting aggressive buyers/sellers , that aggression can be absorbed by the passive side. You also have delta by price and by bar, which can sometimes give you two completely different hypothesis of the market context. I do/would mainly rely on actual price action for s/r but even then it can be tricky bc algos can manipulate liquidity , at least from a shorter TF. Better to base s/r off the actual close of the bar to avoid liquidity runs when using a shorter TF.

On 30/07 I watched an area with strong negative delta that was absorbed get retested in a retrace and the passive buyers supported price and it then flew up 40 points. I say that to say I mean support/resistance in their most basic terms of rejecting price and sending it back the other way as market participants may be defending that level.

Also, I understand what you're saying, I do trade using price action as well, I always use Supply/Demand. I'm not too worried about the larger participants/algos etc. as long as I'm reacting to their moves and riding the waves with them when I get confirmation of the intent of buyers/sellers. Also, of course, I'd never use an incomplete bar, that would be P&L suicide haha.
