How to define a valid trading range before placing orders

Published by Sarah Whitfield · Updated August 2025

Many traders draw a box around recent price and call it a range. By the next session the box is wrong, levels are moved, and entries feel random. A valid range — one you can actually trade from — needs evidence that both buyers and sellers are accepting prices between two boundaries.

Check one: repeated touches, not single spikes

A boundary earns a horizontal line when price has tested it at least twice and reversed without immediately breaking through. A lone spike above the prior high is a liquidity grab, not an upper boundary. Wait for a second visit or a failed close beyond the extreme.

In our workshops we print the prior five sessions and mark only levels with two touches. The constraint feels slow, but it filters most false boxes.

Check two: time spent inside, not just distance

Vertical height alone does not make a range. Price can oscillate in a wide band while still trending. Look at how many hours price spends between proposed boundaries without closing outside. On a four-hour FX chart, a consolidation often shows four to eight bars contained before a credible range exists.

Check three: reaction levels align with boundaries

Inside the box you should see mid-range pivots — prices where candles repeatedly wick and reverse. If the only "levels" are the outer edges, the market may be drifting rather than ranging. Reaction levels give structure between boundaries and help you avoid chasing every move to the centre.

When to discard the range

Remove the box when a session closes beyond a boundary with follow-through, or when volatility collapses so much that spreads dominate the chart. Sitting flat is part of range trading. Redrawing every hour usually means the range was never valid.

Practical next step

Pick one instrument you watch during London hours. Mark boundaries using only the three checks above for a full week without placing trades. Journal whether each box survived the next session. That audit alone clarifies whether you are trading ranges or trends dressed as consolidation.
