Mountain Chart
A line chart with the area under the line filled, so the path of price looks like a ridge.
Teaching sketch. It shows the shape, not a live quote and not a trade signal.
Definition
A mountain chart is a close-price line with shading down to the baseline. It is a presentation of a line chart, used often on long-term performance pictures. It does not add open, high, or low.
How it works
The fill makes the direction obvious at a glance and makes a small wiggle look more dramatic than it is. The information is still one price per period.
How to identify it
A filled silhouette under a single line, usually of closing prices or of an index level. No candles.
How traders use it
Useful for a long history where candle bodies would be a smear. Not useful for an entry that depends on a wick or a range.
Common mistakes
Reading the shaded area as volume. The shade is decoration under the price line.
Limitations
Everything a line chart cannot show, a mountain chart cannot show either.
This note explains the term. A sketch shows the shape of the idea. Neither is a recommendation, a signal, or a comment on any security. Indicator settings and exchange conventions differ. Check the live chart and the contract specification before you use a number.
