Each follower account in a copy group has two settings that control how it replicates the leader: the quantity multiplier, which determines how many contracts the follower trades, and the copy type, which determines which contract the follower trades.
You might need this article if:
You want to understand how the multiplier affects follower position sizes
A follower is trading more or fewer contracts than you expected
You want to set up a follower to always trade micro or mini contracts regardless of what the leader trades
You are scaling up or down for a funded account and need to understand the rounding behaviour
You want to understand how multiplier and copy type interact when both are configured
How the quantity multiplier works
The quantity multiplier scales the follower's position size relative to the leader. The formula is:
Leader contracts × multiplier = follower contracts (always rounded up to the nearest whole contract)
Results are always rounded up — never down, never truncated. If the result is a whole number, no rounding occurs. If the result is fractional, it becomes the next whole number.
Leader | Multiplier | Raw result | Follower trades |
1 contract | 0.5× | 0.5 | 1 contract |
1 contract | 1.3× | 1.3 | 2 contracts |
3 contracts | 0.5× | 1.5 | 2 contracts |
3 contracts | 1.5× | 4.5 | 5 contracts |
9 contracts | 1.3× | 11.7 | 12 contracts |
Both whole numbers and decimal multipliers are supported. Common values: 0.5×, 1×, 1.3×, 1.5×, 2×, 2.5×, 3×.
Practical note for funded accounts: Prop firms set a maximum number of contracts per account. If your multiplier causes the follower's calculated size to exceed that limit, the broker will reject the order. Set your multiplier with the follower account's contract limit in mind. See Is my prop firm compatible with Tradecopia? for compatibility guidance.
How copy type works
Copy type (also called contract mode) determines which contract the follower trades — regardless of what the leader is trading. This setting applies even if the leader switches contract types mid-session.
Copy type | What the follower trades |
Standard | The same contract as the leader — exact match |
Micro | Always micro contracts (e.g. MES, MNQ) |
Mini | Always mini contracts (e.g. ES, NQ) |
Use Standard when the leader and follower should trade the same contract. Use Micro or Mini when the follower should always trade a specific contract size regardless of the leader's contract.
How multiplier and copy type combine
When both a multiplier and a copy type are set, Tradecopia applies the multiplier first, then converts to the specified contract type.
Copy type | Leader | Multiplier | Follower trades |
Standard | 2 NQ | 2× | 4 NQ |
Micro | 4 NQ | 4× | 16 MNQ |
Mini | 8 MNQ | 2× | 16 NQ |
Micro | 1 MNQ | 5× | 5 MNQ |
The third row illustrates an important point: Micro and Mini modes convert in both directions. A follower set to Mini will trade NQ even when the leader is trading MNQ — the copy type forces the contract, not just the direction.
Where to configure these settings
Multiplier and copy type are configured per follower account when you create or edit a copy group. Both controls appear side by side for each follower you add. To access them, go to Copy Trade → open or create a group → Follower Accounts section.
