What are premium and discount?
Last updated: 22 September 2026
Premium and discount split a range in half and give each half a name. Above the midpoint is premium, where selling is considered the better side. Below it is discount, where buying is. The midpoint itself is called equilibrium. It is an old idea wearing new clothes: draw a Fibonacci retracement across the same range and the fifty percent line lands in exactly the same place.
How to mark it
The hard part is not the maths, it is choosing the range.
- Pick a swing that matters: a clear low to a clear high, or the reverse, on the timeframe you are actually trading.
- Find its midpoint. Half the distance, nothing more complicated.
- Everything above is premium, everything below is discount.
Change the swing you measured and every label on the chart changes with it. That is the whole weakness of the idea, and pretending otherwise is how people convince themselves that price is at a discount when they simply wanted to buy.
What it is actually for
It is a filter, not a signal. The rule most traders apply is that in an uptrend they look for buys only in the discount half, and in a downtrend they look for sells only in the premium half.
What that removes is the worst version of a good setup: the valid looking entry taken at the most expensive price in the range. A zone that is perfectly drawn but sits in premium while you are trying to buy is telling you something, and it costs nothing to listen.
Why it is the same as the fifty percent retracement
Draw a Fibonacci retracement from the low to the high of the same swing. The 0.5 level is the equilibrium. The 0.618 and 0.705 levels, which get a lot of attention in this vocabulary, sit just inside the discount half.
This matters for one practical reason. If you already use retracements, you do not need to learn a second system; you need to name the halves. Knowing that two vocabularies describe one line is what stops you from counting the same evidence twice and calling it confluence.
Where it breaks down
- In a strong trend. Price can spend days in premium and keep rising. Refusing to buy above the midpoint means missing the whole move.
- With no clear range. If you cannot point at the swing low and swing high, the midpoint is invented.
- When the range is stale. A midpoint from two weeks ago describes a market that no longer exists.
- When it is chosen after the fact. Any price can be made to look like a discount by picking a wider swing.
The mistakes that cost the most
- Treating it as an entry. Discount is a condition, not a reason. Something still has to happen at the price.
- Redrawing the range until the answer is the one you wanted. This is the most common and the least noticed.
- Mixing timeframes silently. Discount on the four hour and premium on the fifteen minute are both true, and choosing between them is the actual decision.
- Counting it twice. Equilibrium and the fifty percent retracement are one piece of evidence, not two.
Questions people ask
What does premium and discount mean in trading?
The two halves of a price range, split at the midpoint. Above the midpoint is premium, considered expensive and therefore the better half to sell in. Below it is discount, considered cheap and the better half to buy in. The midpoint is called equilibrium.
Is equilibrium the same as the fifty percent level?
Yes. Equilibrium is the midpoint of the range you measured, and a Fibonacci retracement drawn across that same range puts its 0.5 level on the same price. Two names, one line, and no extra information in the second name.
What is optimal trade entry?
Optimal trade entry, shortened to OTE, is the narrower band inside the discount half that some traders prefer, usually between the 0.62 and 0.79 retracement of the swing. It is a preference about where inside the discount to act, not a separate concept.
Which range should I measure?
The most recent swing that the current move is working inside, on the timeframe you trade. If two people disagree about whether price is at a discount, they are almost always measuring different swings rather than disagreeing about the maths.
Reading the range without measuring it by hand
Trading AI reads a photo or a screenshot of any chart and returns the market structure it finds, the key levels, the order blocks and the fair value gaps, with a trade plan and the risk that goes with it. Seeing which half of the range a zone sits in is what turns a valid setup into a well priced one.

The swings you measure between are read from this: What is market structure?
And a zone at a discount is worth far more than the same zone at a premium: What is an order block?
