Tight Trading Range on USD/CHF - But Could we see a breakdown?

The USD/CHF began trading lower for years, rallied, and now we're in a very tight trading range. But as with many of the USD/X pairs, we can see large areas of low-liquidity below price. That means that if we trade into those areas, we could see a serious markdown in price.

To see what I mean by low-liquidity on the chart, look at the yellow box where price hasn't traded very much - just a few candles.
