Hello guys,
To answer some questions:
-You can already chose your swap type, daily or term, on your active positions. But the change will be active only after the 21st of July. We offer you this option now in order for long term position holders to make sure to set their preferences before the change is active
-Regarding the "term" option: yes we are compounding interests payment. WHich is why the default option is "daily", and which is why if you plan on holding a long term position be carefully with this. I hope you understand the reasoning here: paying lenders at the end of their swaps but charging traders at the term of their position meant we were lending money at 0%. Which poses legal problems, and increased our risk by using our capital for what it was not supposed to be used.
"How will this work, in case the position is full leveraged but still above the margin call level,
i.e. the Tradable Balance is equal or less than 0 and the Margin Balance is above the Required Margin ?"
We will still borrow additional swap to match your unrealized swap, no matter your tradable balance.
One last change that is upcoming on the 21st of July as well:
Leverage calculation: The currency that is used as collateral for your open position(s) does impact your risk of default in case of a forced liquidation. If you have 3 BTC and take a 6 BTC position, your true leverage, regarding exposure to BTCUSD price, is 3:1, not 2:1. We thus will include the collateral that is not in the last currency of a traded pair as part of the position cost (ie all non-USD collateral for BTCUSD and LTCUSD positions, and all non-BTC collateral for LTCBTC positions).
Your tradable balance is equal to:
( Your leverage * your margin balance (in USD) + your unrealized profit + your unrealized swap) - your position(s) cost (in USD)
Today, your position cost is equal to:
( your position base price * your position size )
After this change, your position cost will be equal to:
(your position base price * your position size + ((your position base price * your position size in USD) - your USD trading balance)
Ok, what does it means in simple term:
1st example
Current BTC price is 600 USD/BTC, and you have a leverage of 2.5:1
If you have 1 BTC, you can open a 1.5 max long or short BTCUSD position
If you have 600 USD, you can open a 2.5 max long or short BTCUSD position
Each dollar you add in your trading wallet will allow you to increase your tradable balance
2nd example
Current LTC price is 0.02 BTC/LTC, and you have a leverage of 2.5:1
If you have 1 LTC, you can open a 1.5 max long or short LTCBTC position
If you have 0.02 BTC, you can open a 2.5 max long or short LTCBTC position
Each bitcoin you add in your trading wallet will allow you to increase your tradable balance
Edit:
Existing positions will not be touched/forced liquidatedIt only impacts your tradable balance, not your liquidation price.
Let me know if you have any questions
