I am trying to set up a limit order to buy Litecoin, but the system is telling me "Insufficient funds" as if it's not linking to my bank account. I never have this issue on regular Coinbase.
I know the funds are there. How can I resolve this??
The funds are where? The bank? Or you have already purchased Litecoin and want to trade?
Know that limit order does not work that way, you will need to have already purchased a coin already before you can make use of limit order to convert from one coin to another. In the case you want to purchase litecoin, not limit order that will be used, use deposit button, but if you want to convert litecoin to another coin on Coinbase Pro, then you can use the limit order for the trade.
