Not quite sure which thread you are referring to. Can you please link? Thanks.
Searching for your posts containing “slippage” or “market protection”,
found this post and this other post.
Both appear to be the same for slippage.
If anything, a Limit Order appears to be more customizable compared to the “Market Protection” feature.
Is “Market order + Market Protection” better in any aspect(s) compared to a “Limit Order” ?
