What do you prefer for a scalping strategy?

I'd vote "Whatever works best for the specific strategy and instrument." Could be neither. Could be both - BE upon reaching one level, TS upon reaching another. This needs testing per strategy. With only two options, I chose not to vote.

Another approach is splitting into multiple positions with staggered TP levels (or partial close, but this is unfriendly to copy-trading). For my NAS100 scalping experiments, this appeared to work better than TS, which would have to be too far (barely reducing the loss rather than locking profit). Another advantage of a lower TP over TS is that over-shoots result in price improvement with TP, but on the contrary with SL. A drawback is that the original trade size needs to be large enough to split. So maybe not for your gold scalper...

Neither.

A reasonable fixed SL, coupled with a "chasing" dynamic exit, e.g., indicator-based. Both must be statistically determined by way of testing.
