# Buy Modes
> Choose how your trade size is calculated on each copied trade.
| Method | How it works |
| :------------------------ | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| 💵 **Fixed Amount** | Same dollar amount every trade regardless of leader's size. Example: always \$5 per trade |
| 📋 **Exact Copy** | Mirrors the leader's exact trade amount. If they buy \$50, you buy \$50. Minimum \$1 |
| 📊 **Percentage** | A % of the leader's trade size. Example: 20% of a \$50 trade = \$10 |
| ⚖️ **Portfolio Weighted** | Calculates what % of the leader's total portfolio value (balance + open positions) they spent, then applies that same % to your portfolio with a ratio multiplier (0.01–10.00x) |
| 💵 **Balance Weighted** | Calculates what % of the leader's available wallet balance they spent, then applies that same % to your available balance with a ratio multiplier (0.01–10.00x) |
**Choosing Between Portfolio Weighted and Balance Weighted**
| Method | Based on |
| :---------------------------- | :--------------------------------------------------------------------- |
| ⚖️ **Portfolio Weighted** | Leader's total portfolio value — balance + all open positions combined |
| 💵 **Balance Weighted** — NEW | Leader's available wallet balance only — excludes open positions |
Use **Balance Weighted** if you want to mirror how the leader sizes trades relative to their free cash, rather than their total portfolio.
**Size Limits (apply to all methods)**
| Setting | What it does |
| :------------- | :---------------------------------------------------------------------------------------------------------- |
| 📈 **Max Buy** | Hard cap per trade. Any calculated amount above this gets capped |
| 📉 **Min Buy** | Minimum per trade. If calculated amount is below this, it gets rounded up. Minimum \$1 (Polymarket minimum) |
***
When **Fixed Amount** is selected, the Min Buy and Max Buy options are automatically hidden. Since the trade amount is already set, these limits don't apply.
