The flags (consolidation patterns) we like are generally 3-4 bars/candles (days) long.

Sometimes they can go for a bit longer, but that’s a good ballpark.

We’re looking for easily recognisable, neat, and compact flags or consolidations, where the difference between entry and Initial Protective Stop is small, thus your 'Practical Risk' is small.
