# Position Sizing

### Ratio-Based Sizing

Configure follower position size as a ratio of leader position:

* **Fixed ratio**: 0.5x leader size (2 contracts → 1 contract)
* **Scale up/down**: Match account size differences
* **Precision control**: Supports decimal ratios

{% hint style="info" %}
**Edge case for 0.25x/0.5x ratio copying**

If leaders is 3 contracts, follower is 1\
If leader is 1 contract, follower is 1 contract\
\
There is a minimum of 1 contract required. Partial or fractional contracts are not possible. 
{% endhint %}

### Maximum Position Limits

Set absolute position size limits per follower:

* **Risk management**: Prevents oversized positions
* **Account protection**: Limits exposure regardless of leader size
* **Override protection**: Max limit overrides ratio calculation

### Contract Size Mapping

Automatic contract size adjustment:

* **ES to MES**: Full-size to micro contracts
* **Maintain ratios**: Proper size relationships preserved
* **Cross-market**: Different instruments with size equivalence
