Range trading and mean reversion
Range trading takes the opposite view from trend following: when a market is clearly bouncing between a defined support and resistance level with no real directional trend, the strategy is to sell near the top of the range and buy near the bottom, betting price reverts back toward the middle rather than breaking out.
This is often called mean reversion, based on the idea that price tends to drift back toward its recent average after stretching too far in either direction — the same logic behind an RSI reading "overbought" above 70 or "oversold" below 30, both signalling price may be due to snap back.
A well-defined range needs at least two clean touches of both the top and bottom to be considered real, the same "tested twice" standard from Module 3's support and resistance lesson. A range someone drew after only one touch on each side is really just a guess dressed up as a level.
The single biggest risk with range trading is a genuine breakout — the exact moment the range finally does what ranges eventually do and breaks, usually taking every range trader positioned against that breakout with it. This is why a stop loss just outside the range boundary isn't optional here; it's the entire difference between a contained loss and an account-ending one.
Range trading tends to suit calmer, lower-volatility periods and instruments — it's a poor fit right before or during high-impact news, when the whole reason for the range (a temporary standoff between buyers and sellers) is exactly what news releases tend to violently resolve.
Key takeaway
Range trading sells the top and buys the bottom of a well-tested range, betting on reversion to the middle — with a hard stop just outside the range as non-negotiable protection against the breakout that eventually comes.
Example
USOIL chops between $68 support and $72 resistance for two weeks, rejecting both levels twice each — a legitimate range, worth selling near $72 and buying near $68, stop just beyond each boundary.
Try this
Find a pair or instrument that's clearly been ranging for at least a week. Mark the top and bottom. Would you have a stop loss placed if you traded this range — and where, exactly?
