What it means
Take a defined range from a swing low to a swing high. The 50% level is equilibrium. Above it is premium (relatively expensive); below it is discount (relatively cheap).
It is a way of locating price within a range, not a valuation.
Why traders use it
Buying in discount and selling in premium improves reward-to-risk toward the opposite end of the range. In a bullish structure, many traders only look for longs below equilibrium.
Chart examples
Premium, discount and equilibrium
How to identify it objectively
- 1Choose the range: the most recent confirmed swing low and swing high of the leg you trade.
- 2Equilibrium = (high + low) / 2.
- 3Above = premium; below = discount.
- 4Re-draw when a new swing high or low forms.
Bullish use
- 1Bullish structure.
- 2Price pulls back below equilibrium into discount.
- 3Look for a bullish setup there; target the high.
Bearish use
- 1Bearish structure.
- 2Price rallies above equilibrium into premium.
- 3Look for a bearish setup there; target the low.
What confirms it
- A setup (sweep, order block, FVG) inside the right half.
- Structure agrees.
What invalidates it
- Price breaks the range extreme against your bias.
- The range was chosen after the fact.
How a hypothetical setup is built
Entry
In discount, on a bullish confirmation close.
Stop
Below the swing low that defines the range.
Target
The swing high (premium end).

Historical testing
Not tested on The Tradeskill yet. As a filter, test it by comparing results of the same entry rule taken in premium versus discount.
Limitations: when it fails
- Ranges are subjective unless swing rules are fixed.
- Strong trends can stay in premium for a long time.
- Equilibrium is not a support or resistance level by itself.
