# VOOI Perps Arena

## Why Use Perps Arena

**VOOI Perps Arena** allows users to compare execution costs across supported perpetual DEX venues and choose where to open a position.

It helps users review available venues for a selected trading pair, direction, size, and leverage from one interface, without manually checking each venue separately.

Users can access Perps Arena without authorization. If a user decides to continue and open a position on a selected venue, authorization is required at that step.

VOOI Perps Arena is part of the VOOI Ultra toolset. Related Ultra tools include:

* [Transfer Margin](/vooi-ultra-v3/vooi_ultra-tools/vooi-transfer-margin.md) for moving free margin between supported venues,
* [Funding Radar](/vooi-ultra-v3/vooi_ultra-tools/vooi-funding-radar.md) for identifying potential funding arbitrage opportunities, and
* [Funding Arbitrage](/vooi-ultra-v3/vooi_ultra-tools/vooi-funding-arbitrage.md) for finding and preparing potential paired long and short setups across supported venues

**Important:**

* Perps Arena is used for comparing supported venues before opening a position
* Authorization is required only when proceeding to open a position

* Final execution conditions may differ depending on market movement and venue-specific execution
