The short answer

TAIL copies eligible activity from supported traders using your own settings. Your mode, trade size, active profile, entry constraints, and exit rules determine whether and how a signal becomes a trade.

A signal still has to qualify.

Tailing someone does not mean every move becomes your trade. TAIL evaluates supported signals against your settings and the available route. A stale signal, insufficient balance, unsupported token, or failed safety check can stop the copy.

Check Activity for the result. A skip means the trade did not qualify under the condition shown. A failed or uncertain execution needs its own result checked; do not assume that a missing success screen means nothing was sent.

Size the copy, not the trader.

Your size is separate from the trader’s size. You can choose an account-level amount and use market-cap profiles for different ranges. Profiles can also control adds, split buys, and exits. The app shows the active configuration; review it before enabling Live.

A split buy spreads an entry into tranches. An add follows an additional entry into an existing position where your profile allows it. Both are different from copying the entire value of someone else’s purchase.

What the limits are for.

ControlWhat to check
Signal ageHow old a signal can be before TAIL skips it.
Size and daily limitThe amount per copy and whether the daily ceiling is enabled.
Slippage and entry settingsThe execution conditions you are willing to accept.
Market-cap rangeWhich profile applies to the token and what that profile allows.

Follow the exit, or set your own.

A proportional exit follows the share of the trader’s position that they sell, applied to your copied position. If they sell a quarter, the intended copy exit is a quarter of your corresponding lot, not a quarter of everything in your wallet.

Your own stop, take-profit steps, and trailing stop can also govern exits. Review the settings for the position you are opening. Prices can move through a trigger, liquidity can disappear, and a route can fail; a configured stop is not a guaranteed sale price.

Why your result can differ.

The trader moves first. Your signal is observed, checked, quoted, signed, and sent afterwards. Price, liquidity, fees, and timing can change between their fill and yours.

Use your receipt to judge your trade. It should tell you what your wallet spent or received and link to the transaction. Another trader’s profit is context, not your result.
