Do you have subaccounts there?
No
And please update us on what's going to happen and why that happened.
It turns out spot margin trading was enabled for my account. I think it's enabled by default. I have disabled it and closed the position as advised by the support
I think at one point while trying to buy the asset I wanted. I borrowed an extra amount without knowing
This was their response
Hello,
Negative balances mean that you are borrowing this amount.
To pay back a borrow in our spot margin system you will need to add more of the specific asset that you are currently borrowing. So if you see a negative ETH balance on your wallet page then you will need to sell another asset that you have for ETH, until your ETH balance reaches 0 again.
You may also market close the position at
https://ftx.com/spot-margin/borrows or buy back the exact amount using the spot market. Please make sure you have the MARGIN flag selected and enter the exact amount you wish to clear.
After you have paid back any borrows if you would like to disable spot margin you can do so in your settings:
https://ftx.com/profilePlease note that due to the minimum tick size of an asset sometimes you may need to end up with a slightly positive balance, it won't be possible to get back to exactly 0.
Feel free to reach out if you have any further queries.
Thanks,
FTX
