It is possible to fund your account with multiple bank cards, meaning no limit to how many different bank cards you can use.

However, do keep the following in mind basic Exness rules:

• Bank card deposits must be withdrawn using the same amount and payment method as the initial deposit.
• A trading account that is funded with multiple bank cards must withdraw the profit separately after the deposit amount has been withdrawn
• The profit withdrawals must be proportional to the deposit amount per bank card.

As an example:
Let’s say you have 2 bank cards, and you use card A to deposit USD 20 and card B to deposit USD 25; this totals USD 45. At the end of your session, you’ve made a profit of USD 45.

Now you want to withdraw the total of USD 90 (including your profit).
You would have to withdraw USD 20 using card A, and USD 25 using card B before you can withdraw the USD 45 profit. As profit withdrawn must be proportional, you would have to withdraw USD 20 from card A, and USD 25 from card B as this is proportional to the deposit amount for both bank cards.

It is advisable to track the amount of how much you have deposited with each bank card in order to facilitate the withdrawal of that same amount and any profits made proportionally, using the same card.
