Order Blocks appear in trending and ranging markets, but how to use them is a little bit different in each market. Order Blocks tend to fail more often in a ranging market or consolidations. This is because Order Blocks form inside the range, but the price tends to run old highs and lows in consolidations and not respect the order blocks.
In a trending market, prices respect Order Blocks more often, which makes them high probability. This is because big players are involved in trading when the market is trending. And when the market is in consolidation, they stay on the sidelines.
As you can see below, Order Blocks in consolidations are Low probability, and they tend to fail more often than not.
