Scalping crypto

Recently, I’ve been analyzing Bitcoin charts across different exchanges on shorter time frames, and I’ve noticed that the volume at the same points in time can vary a lot between exchanges.

When it comes to scalping, I always lean on L2 data like footprint charts, CVD, and similar tools. With the data being so inconsistent, how do you guys approach scalping crypto? Which exchange do you trust for reliable L2 data?

In the screenshots, you can see the BTCUSD charts from two different exchanges, and there’s a noticeable difference in volume levels at the same time. If something as aggregated as volume is so different, I can only imagine how more granular L2 data like bid/ask imbalances or volume profiles could also vary significantly. Thoughts?
