Documentation for eth_defi.one_delta.position.close_short_position function.

close_short_position(one_delta_deployment, *, collateral_token, borrow_token, atoken, pool_fee, wallet_address, exchange=Exchange.UNISWAP_V3, interest_mode=AaveV3InterestRateMode.VARIABLE, withdraw_collateral_amount=115792089237316195423570985008687907853269984665640564039457584007913129639935)[source]

Close a short position using flash swap then withdraw collateral from Aave.

NOTE: - only single-hop swap is supported at the moment - withdraw_collateral_amount should be used wisely in case there are multiple positions opened with same collateral, it will affect the collateral amount to be left on Aave to back other positions hence affecting the liquidation threshold as well.
