Margin
All trading and liquidity providing on Vertex is done on margin.
Your margin is in essence your account's value: collateral + PnL from positions
When opening positions on Vertex, there are some terms you should get familiar with.

Margin usage:

A measure of how much total available leverage (before liquidation) you are consuming.
Example:
  • User's account value is $100
  • They have an open trade and LP position which together equates to 10x leverage
  • Since Vertex lets users take up to 44x leverage, the margin usage is 22.7%

Margin fraction:

Calculated using account value/sum of position values. This won't be displayed on the Dashboard but it's important to know for when it comes to maintenance margin.
Example:
  • Taking the scenario above, consider PnL = 0 for simplicity
  • Account value is $100, position values = $1000 because combined are 10x leverage
  • Margin fraction: $100/$1000 = 0.1

Maintenance Margin

This is the minimum margin fraction a user's account must maintain. If a users margin fraction gets close or dips below the maintenance, they risk liquidation (see Liquidation).
For FX pairs on Vertex, the maintenance margin is 0.01
Example:
  • If your account value = $1
  • You can have positions that = up to $100 before getting fully liquidated
