Risk is easy to measure and easy to compare: the distance from entry to stop. Room is neither, and it decides as much. A long taken near the bottom of a range has the entire range above it before it meets the price that has already rejected it twice. The same long taken near the top has almost none, and its target sits beyond a level the market has to break first. This is the argument behind premium and discount, and it holds whether or not you use an indicator to draw it.

The same risk, a different reward

Suppose a range from 100 to 120 and a stop that is always two points away. Long at 103, the range gives you seventeen points of room before the ceiling; the trade risks two to make seventeen if it simply travels the range. Long at 117, the same two points of risk buy you three points of room. Nothing about the setup changed except the entry, and the ratio went from eight to one down to less than two to one.

Where the stops are is not symmetrical either

The edges of a range are where orders accumulate, and they accumulate differently at each edge. Buying near the top means the nearest pool of resting sell stops is behind you and the nearest liquidity target is far above. Buying near the bottom puts that pool underneath, where a sweep of it is the very thing that often starts the move you are trying to catch. The entry decides which side of the liquidity you are standing on.

The trap of waiting for confirmation

Confirmation costs room. Every bar you wait for a signal to become convincing is a bar in which price travels away from discount and towards premium, and by the time a move looks safe it is often expensive. This is not an argument for entering blind. It is an argument for knowing what the wait costs, and for measuring it in the same units as everything else: how far up the range you are now paying.

What this does not mean

Discount is not a buy signal. Price can sit in the lower quarter of a range for weeks, or leave through the bottom and turn that range into the upper half of a new and lower one. The reading says where you are relative to a range that exists right now, not whether that range will hold. Treated as a filter on trades you were already going to take, it is useful. Treated as a reason to take a trade on its own, it is not.

Reading it alongside structure

The reading gets far more useful next to a structural one. A long in discount, taken after a sweep of the low and a shift in structure, is three arguments pointing the same way. A long in premium with structure still bearish is one argument fighting two. The zone does not overrule anything; it tells you whether the trade you like is being taken from a good place or an expensive one.
