Range trading: making sense of a sideways market

Crypto spends a lot of time going nowhere. How to trade a sideways range and what to check so you notice when it ends.

Key takeaways

  • Only trade a range after at least two touches of both support and resistance.
  • Buy near the edges, never the middle, with the stop just outside the range.
  • After a decisive close beyond either edge, stop range trading. It is now a breakout.

For all its reputation for wild moves, crypto spends long stretches going sideways. Range trading buys near the bottom of a sideways channel and sells near the top. It is the mirror image of breakout trading, and it fails exactly when a breakout succeeds.

How a range trade works

Once price has bounced between the same floor (support) and ceiling (resistance) a few times, many traders expect it to keep doing so. They buy near support, take profit near the middle or near resistance, and keep a tight stop just outside the range. Momentum indicators such as the RSI help time the edges: an RSI near or below 30 turning back up near support is a typical buy signal.

“Oversold” can stay oversold for a long time. An RSI below 30 in a strong downtrend is a warning, not a buy signal. RSI signals mean something only inside a range you have already confirmed.

What to check

  1. Is it really a range? You want at least two clear touches of support and two of resistance. Before that, you are guessing where the edges are.
  2. Have the trends gone flat? Flat moving averages with price crossing back and forth over them are the hallmark of a range. If the averages are sloping steeply, the market is trending and fading its moves is fighting it.
  3. Is the range wide enough? The trip from support to resistance has to cover fees, spread and slippage several times over. A narrow range on a low-liquidity coin can leave nothing after costs.
  4. Are you buying near the edge? Range trades only make sense near the edges, ideally in the bottom quarter. Buying in the middle of the range gives you the same stop distance with half the upside.
  5. Is momentum turning? Look for the RSI to turn up from oversold, or for bullish divergence: price makes a slightly lower low while the RSI makes a higher low. Both suggest sellers are tiring.
  6. Is a catalyst coming? Ranges often end on news. A big macro release or a coin-specific event during your trade raises the odds that this is the touch where support breaks.
  7. Where is your exit if the range breaks? The stop goes just outside the range. And after a decisive daily close beyond either edge, stop trading the range entirely. It has become a breakout, and breakout trading applies instead.
