The claim feature allows the use of funds you have in your Margin Wallet to settle a leveraged position as an exchange buy or sale. Claiming some or all of a position requires that you have enough partially realized P/L (you've reduced the position at a profit) and/or funds (BTC or USD) in your Margin Wallet (net of any outstanding financing charges) to satisfy some or all of the outstanding financing associated with your position.
