# Sizing Modes

> Three ways to size copied trades.

How much you spend on each copied trade depends on the sizing mode you pick when creating the strategy.

</Frame>

<AccordionGroup>
  <Accordion title="Fixed — same dollar amount every trade">
    You set a fixed USD size (e.g. \$25). Every copied trade uses that amount, regardless of how much the leader spent.

    Best for: predictable bankroll usage, beginners.
  </Accordion>

  <Accordion title="Percentage — a % of the leader's trade">
    You pick a percentage (1%–100%). If the leader buys $1,000, and you set 5%, you buy $50.

    Best for: scaling with confident leaders without going all-in.
  </Accordion>

  <Accordion title="Portfolio-Weighted — true portfolio mirror">
    PolyWin tracks your leader's full portfolio in the background and sizes every trade so your allocation matches theirs proportionally to your bankroll.

    **Multiplier:** apply a multiplier to your share — presets `0.3x · 0.5x · 1x · 2x · 5x · 10x` or set any custom value from `0.01` to `10`. `2x` mirrors the leader at twice their portfolio weight, `0.5x` at half. Default is `1x`.

    </Frame>

    Best for: serious copy traders who want a faithful mirror of a top wallet, optionally amplified or dampened.
  </Accordion>
</AccordionGroup>

<Note>
  Every mode respects your **min** and **max** per trade caps. A copied trade outside those bounds is skipped or clamped.
</Note>

<Warning>
  Switching sizing mode mid-strategy applies only to future trades. Existing positions are not resized.
