What is PD Arrays (Premium/Discount Arrays)?
The ICT menu of institutional price zones — FVG, Volume Imbalance, IFVG, SIBI, BISI, Balanced Price Range, Order Blocks and Consequent Encroachment — always read against the premium/discount of the dealing range.
PD Arrays are the zones the algorithm delivers price through. The imbalance family: FVG (3-candle wick gap), Volume Imbalance (body-to-body gap), IFVG (a violated FVG that flips polarity), SIBI/BISI (one-sided sell/buy imbalances), BPR (overlapping opposing FVGs acting as equilibrium), and CE — the Consequent Encroachment, the 50% midpoint of an FVG that the algorithm respects with remarkable consistency.
The "PD" half is the discipline: the same array means opposite things depending on where it sits in the dealing range. A bullish FVG in discount is an A+ long zone; the identical FVG in premium is a trap. Array first, location second — both must agree.
Practical hierarchy for entries: CE of an FVG (tightest stop) → FVG edge → OB mean threshold → BPR boundary. When multiple arrays stack at one price, that confluence is the institutional footprint.
