Return displays, examined
Every copy-trading leaderboard is an editorial product. Three editorial decisions — the window, the survivors, the fees — do most of the work.

A number on a leaderboard feels like a measurement. It is closer to a sentence: someone chose the subject, the tense, and what to leave out. Before copying anyone on any platform, it is worth knowing the three choices that shape nearly every return display in this industry.
The window
A displayed return covers a period, and the period is a decision. Twelve trailing months flatters a trader whose bad year was thirteen months ago. A year-to-date figure resets every January, absolving whatever happened in December. Platforms generally let you switch windows; defaults, though, do the real work, because defaults are what most eyes see. The actuarial habit is to ask of any figure: who chose this window, and what would the adjacent windows show? A trader who looks brilliant over six months and unremarkable over three years is telling you which window their marketing prefers.
The survivors
Leaderboards rank the traders who are still there. The ones who blew up, went quiet, or deleted the account are not ranked; they are simply gone, taking their returns with them. This is survivorship bias, and it operates on every ranking of live accounts, on every platform, without any bad faith required. The visible population is the successful remnant of a much larger cohort you cannot see. A leaderboard therefore answers a narrower question than the one you are asking. You want to know what happens to people who start copying trades; it shows you what happened to the subset for whom it went well enough to still be on the board.
The fees
A return can be quoted before or after costs, and the difference compounds. Spreads on every copied position, overnight financing on leveraged ones, subscription or profit-share fees where the model includes them — whether a display nets these out varies by platform and is not always prominent. A leader’s gross performance is also not your net performance for structural reasons: your copies execute moments later, at whatever price is then available. The gap is usually small and always in doubt.
None of this requires a villain. Windows must be chosen, departed accounts cannot be ranked, and fee treatment is genuinely complicated. But the sum of three reasonable choices is a display that flatters systematically — and a displayed past, however honest, is still only a past. The capital you would place behind it lives entirely in the future, where no window, survivor, or fee note applies. That gap is the risk, and the copier carries all of it.
