A copy ratio scales every leader order on a follower: at ×2, a 1-contract leader trade becomes 2 contracts. That works until the leader trades more than one market. NQ and ES move very different dollar amounts per point, and a follower sized right for one is often wrong for the other. Per-instrument ratios let one follower copy NQ at ×3, ES at ×5 and everything else at its normal ratio.
A follower has a copy ratio of ×1 and two rules: NQ ×3 and ES ×5.
| Leader order | Rule used | Follower order |
|---|---|---|
| Buy 1 NQ | NQ ×3 | Buy 3 NQ |
| Buy 2 ES | ES ×5 | Buy 10 ES |
| Sell 1 ES (partial exit) | ES ×5 | Sell 5 ES |
| Buy 1 MYM | No rule → copy ratio ×1 | Buy 1 MYM |
Every copy is still the leader’s order size × a ratio. Rules never size a follower from positions, so adds and partial exits stay in proportion and the follower goes flat with the leader.
A rule can also switch the follower to the micro: NQ → MNQ ×5 copies each leader NQ order as five MNQ. See copying NQ as MNQ.
In the Cockpit, click + Set size per instrument in the follower’s Size × leader column, add one row per instrument, and save. The row then shows the rules in short form, for example “NQ ×3, ES ×5”. Step by step: per-instrument rules guide.
Yes. Add per-instrument rules on the follower, for example NQ ×3 and ES ×5. Instruments without a rule copy at the follower’s normal ratio.
Whole numbers from 1 to 100.
Yes. Every leader order in that instrument, entries, adds and exits, is copied at the rule’s ratio, so the follower stays in proportion and goes flat with the leader.
Each copy is sized with the rule in force when it is sent. Changing the ratio mid-trade would size the exit differently from the entry and could leave the follower holding a position the leader has closed.
