The popular notion, in markets, that if the buyer is right then the seller must be wrong, is nonsense.

Nonsense because it implies only one prospective future path, and that it can be ascertained (predicted) via deeper insights.

Both can be right and both can be wrong

Both can be right, because it may be part of a rational strategy for both.

You are right if you're process and rationale is sound, not if you predict the future.

People confuse making sound judgements about what is playsible, with predicting the future.

People also forget that rational trades are often driven by portfolio construction considerations, rather than binary 'right' or 'wrong' judgements.

Uncertainty demands position size considerations.
