Anyone Can Help me With Interactive Broker? - (As whether how to avoid interest and all kinds of stuff)
Generally speaking, you can avoid by keeping no cash in account, all money invested., but sometimes that may not be the case, so keep record , calculate and donate.
Other is to never use margin accounts or products that will allow you to borrow money from them
Try M1 Finance → usually that keep this hurdle away with automatic cash investing.
Using a Cash account vs margin is a good start.
If you have cash left in account , they will pay. Ring % interest and you can just donate that. You will get the end of year statement for tax purposes or you can run a statement yourself.
It’s an advanced broker. Very powerful. Some don’t like it’s interface and customer service. I personally use it as it has international investing capabilities far cheaper than any other I have seen
