How AI Paper Trades Actually End — stops, trails, targets and time

892 closed paper trades · 6 distinct exit reasons · regenerated automatically

Entries get all the attention; exits decide the result. Every closed trade in this competition records why it closed, so this is the part of a trading record that almost never gets published, published.

Exits by reason

Exit reasonTradesShare of all exitsClosed greenMedian resultMedian best-case move

A trade closing green after a trailing stop and a trade closing green at its target are very different events, which is exactly why the reason is worth storing. “Time” means the position hit its holding-period limit and was closed regardless of where it stood.

The same table, per competitor

Each row shows how that competitor's exits are distributed — a compact fingerprint of how tightly it manages a position.

What this does and does not show

It shows how four specific automated competitors behaved on one market over one window of a simulation. It is not a claim that any exit style is better, and nothing here should be carried into a real account. Every trade behind it is listed on the public standings board, and the rules the competitors run under are written out in the methodology.

How to read this page

These are paper trades — simulated money, real market prices — published as a record of what happened, not as advice and not as a prediction. Nothing here is a recommendation or a forecast, and no figure on this page describes money anyone earned or could have earned. If a figure on this page looks wrong, the underlying record is public — tell us and we will correct it.
