Premium, Discount, and Equilibrium: Mapping Institutional Price Arrays

The premium/discount model is the backbone of SMC bias. Instead of buying because a setup "looks good," you buy only when price is in discount and sell only when it is in premium. The equilibrium line is the divider that turns the model into a mechanical filter.

Building the range. Identify the most recent confirmed swing high and swing low on your higher timeframe (typically H4 for intraday, D1 for swing). Draw the range between them. The 50% level of that range is equilibrium. Above 50% is premium; below 50% is discount.

The 50% rule. Equilibrium is rarely a precise entry. It is a bias switch. In a bullish structure, you seek longs in discount (below 50%) and avoid longs in premium. In a bearish structure, you seek shorts in premium (above 50%) and avoid shorts in discount. Crossing equilibrium flips the statistical edge.

Why the 50% matters. Smart money accumulates below the midpoint and distributes above it. The 50% level is also where the Fibonacci 0.5 sits, often the equilibrium of the deal range. Price spends roughly 60% of its time oscillating around this level before the next leg, making it a high-gravity zone.

Premium array. From 50% to the swing high, look for sell setups: bearish order blocks, bearish FVGs, and liquidity pools above. Valid shorts typically form in the 70-100% premium zone. Entries above 90% are chasing and reduce risk-reward.

Discount array. From 50% to the swing low, look for buy setups: bullish order blocks, bullish FVGs, and liquidity below. Valid longs form in the 0-30% discount zone. Below 10% is often a trap awaiting a final sweep.

Equilibrium retest entry. When price retraces exactly to the 50% level after a BOS and forms a lower-timeframe CHoCH, this is a high-probability continuation entry. Stop goes beyond the swing extreme; target is the opposite liquidity. Risk-reward typically 1:3 or better.

Invalidation. A candle close beyond the swing high or low invalidates the current range and requires drawing a fresh range from the new extremes. Never trade a stale range; equilibrium derived from an outdated swing pair produces false signals.

Multi-range logic. When HTF (D1) and MTF (H4) ranges disagree, defer to the higher one. If D1 says price is in premium but H4 says discount, you are in a D1 premium retracement, not a buying opportunity. Align at least two timeframes before committing risk.
