Sizing rules
Every setting on a copy rule and the order the checks run in.
| Setting | What it does |
|---|---|
| Sizing mode | Ratio: margin = leader's margin × ratio. Fixed: the same margin every time. |
| Max margin per copy | Hard cap on margin, whatever the leader does. The brief's example: leader opens $1k, your cap is $100 → you open $100. |
| Max leverage | Copies use the leader's leverage, capped here. |
| Max open copies | How many of this leader's positions you will hold at once. |
| Max entry drift | Skip if the latest tape price is more than this many bps from the leader's entry. |
| Daily loss stop | Stop opening new copies once today's realised PnL from copies is below −limit. |
| Ignore leader opens below | Filter out the leader's small or test trades by notional. |
| Markets | Copy BTC, ETH or both. |
| Mirror closes | If off, copies are opened but you close them yourself. |
Minimum position value
Papertrade requires margin × leverage of at least $10,000 and margin of at least $10. If your sized copy falls below $10,000 notional, the engine raises leverage (never above your cap) rather than margin, so you never risk more than you asked. If even the cap cannot reach $10,000, the copy is skipped and the reason is logged.
Order of checks
- Rule enabled, market allowed, leader trade above your minimum
- Open-copy cap and daily loss stop
- Entry drift against the latest tape price
- Size, then minimum margin and minimum notional adjustments
- Available balance (paper balance in paper mode, Papertrade available balance live)
