# Trade Size

In order to ensure <mark style="color:blue;">**maximum capital efficiency**</mark>, in other words, protect pools from being drained while allowing for large enough position sizes and potential earnings, **limits** are applied on the open interest and max PnL.

These limits depend on the **current TVL of the pools** and can be adjusted accordingly by the team to ensure the capital efficiency.

{% hint style="info" %}
**Example**

\
Consider the following conditions:

* $10M TVL on the platform
* 10% open interest limit, resulting in $1M limit for both LONG and SHORT
* Currently $100k LONG open interest and $200k SHORT open interest<br>

This means a user could open a LONG position of up to $900k and a SHORT position of up to $800k.
