Range
A market bounded between a clear high and low, with no directional trend.
Also called: trading range · sideways market
Written by Javier Sánchez Ros
In plain language
A range forms when buyers reliably defend a floor and sellers reliably defend a ceiling. Price oscillates between them.
Ranges reward the opposite behavior from trends. Buying weakness at the low and selling strength at the high works here and fails badly once the range breaks.
Every range eventually ends. The break is often violent because stops accumulate on both sides of the boundaries.
Worked through
Trend rules applied inside a $4 range
- Range low
- $52.00
- Range high
- $56.00
- Breakout buys near
- $56.00
- Price then returns to
- $52.00
A trend-following rule buys strength, so inside a range it buys at the top and sells at the bottom — the exact inverse of what the market is doing. Run it through three or four oscillations and the account bleeds steadily on a stock that finished where it started.
The range playbook is the opposite: buy near the low with a stop just below it, sell near the high, and expect the middle to go nowhere. Same chart, opposite instructions, and the only thing that decides which is correct is whether the boundaries are holding.
What makes ranges genuinely useful is that the boundaries are close. A long at $52.30 with a stop at $51.70 risks 60 cents for a $3.70 move to the other side — a ratio that is difficult to find in a trending market, precisely because the invalidation level is right there.
The cost is the breakout. Ranges end, and when they do the range trader is short at the top of a move that keeps going. That is why the stop sits outside the boundary rather than at it, and why a broken range is a reason to stop applying range rules rather than to fade harder.
Why it matters
Identifying a range tells you which playbook applies, and the boundaries provide clean, close invalidation levels for either side.
Common mistakes
- Applying trend-following rules inside a range and taking repeated small losses.
- Assuming the boundary will hold on every touch. Each test weakens it.

These concepts are connected. Understanding one usually makes the next one easier.
A period where price moves sideways in a narrow range without clear direction.
A price area where buying has repeatedly been strong enough to stop a decline.
A price area where selling has repeatedly been strong enough to stop an advance.
When price moves decisively beyond an established support or resistance level.
A move beyond a key level that quickly reverses back inside the prior range.
