# Symbol mapping

> Have a follower trade a different contract from the lead, such as MNQ when the lead trades NQ, with its own multiplier.

**Symbol mapping** lets a follower trade a different contract from the lead. The most common use is copying minis to micros: the lead trades NQ and the follower trades MNQ.

CopyFlock never converts contracts on its own. Without a mapping, the follower trades the same contract as the lead.

## Add a mapping

In the follower's copy settings, under **Symbol mapping**:

1. Click a preset, such as **NQ → MNQ ×10**, or click **Add mapping** to create your own.
2. Enter the **lead symbol** (for example `NQ`) and the **follower symbol** (for example `MNQ`).
3. Optionally enter a **multiplier**.

Use the contract's root, such as `NQ`, not a dated contract such as `NQZ6`. A mapping for `NQ` matches every NQ contract month, and the follower trades the current front month.

A follower can have a mapping for each market you trade, such as NQ → MNQ and ES → MES. Each lead symbol can be mapped once.

### Presets

| Preset | Market |
| - | - |
| NQ → MNQ ×10 | Nasdaq-100 |
| ES → MES ×10 | S\&P 500 |
| YM → MYM ×10 | Dow |
| RTY → M2K ×10 | Russell 2000 |
| CL → MCL ×10 | Crude oil |
| GC → MGC ×10 | Gold |

## How the multiplier works

<Info>
  A mapping's multiplier **replaces** the follower's sizing method for that symbol. The follower trades the lead's contracts × the mapping multiplier.
</Info>

* **With a multiplier:** follower contracts = lead contracts × multiplier, rounded to whole contracts.
* **Without a multiplier:** the follower's normal [sizing method](/settings/position-size) decides the size, and only the contract changes.

**Min contracts** and **Max contracts** still apply in both cases.

### Choosing a multiplier for minis to micros

Each of these micros is one tenth the size of its mini. For example, MNQ is \$2 per point and NQ is \$20 per point.

| Lead buys 2 NQ, mapping NQ → MNQ | Follower trades | Exposure compared with the lead |
| - | - | - |
| ×10 | 20 MNQ | The same |
| ×5 | 10 MNQ | Half |
| ×2 | 4 MNQ | One fifth |
| ×1 | 2 MNQ | One tenth |

Whole-number multipliers keep partial exits clean. If the lead scales out of 1 NQ, a ×5 follower closes exactly 5 MNQ.

### Micros to minis

You can also map the other way, for example MNQ → NQ ×0.1, so 10 MNQ on the lead becomes 1 NQ on the follower.

<Warning>
  Be careful with rounding. 5 MNQ × 0.1 is half an NQ, and scaling out of 3 MNQ becomes 0.3 NQ, which can't be copied exactly. Only map micros to minis if the lead always trades in multiples of ten.
</Warning>

## Good to know

* Stop loss and take profit orders are placed on the mapped contract.
* Your prop firm may count micros differently towards position limits. Check before choosing a multiplier.
