Barts (AKA bull or bear traps) are a common pattern in cryptos. The OBV indicator can be useful for detecting Wyckoff style accumulation or distribution.
It's especially useful for Barts which have a very flat section of price action which makes the OBV divergence very apparent in some cases. If you see a flat zone that looks like a potential bart, track it on a couple different time frames and see if a divergence pops out, it might show which wyckoff mode it's in.
