People said TransferWise cannot transfer USD Into IBKR. Only EUR
If you have borderless account you can bank in USD as it's considered local transfer under your own name.
But since TransferWise shut down borderless account for Malaysian unlikely you will have it.
Which means any USD transfer coming from Ibkr is considered third person transfer which means automatically blocked by IBKR.

Also is there a US Total Market Index Fund ETF? Not just the s&p500?

Tradestation Support

Can I deposit funds using Transferwise/Revolut or other currency transfer services?
While it is possible to deposit funds by this method, the transfer would need to meet the following conditions:
The funds would need to originate from an account titled the same as the IBKR account;
The deposit payment details would need to include your account ID and title.
Based upon prior experience, Transferwise and similar services generally do not include the required information in the payment details and, if this is the case, the funds will be returned as unidentified.
Did you register a new account with tradestation and use wise to fund the account for the first time? Or have you been using it for a while and funding with other methods before? Maybe this doesnt work on first time funding only.

Could you show step by step how to transfer with wise? Super newbie here I have only been using stashaway before this.

Keep in mind they will ask proof of transfer, proof of funds 6-7 months down the road. Kindly take note. This is p ice to pay by using TransferWise. No such issue if money come from sg banks.
