Hi Lix, this is a tricky question and I’d be interested to know the answer to it myself.
Have you put this to a broker like Interactive Brokers to see what they say?
I would think most decent platforms these days will show your net P&L if you click into the trade history/details.
I’m not sure on Q2. I would think youre not using leverage unless your position size exceeds your available cash?? I don’t think a broker would charge interest if you’re not borrowing beyond your cash equity, but again I’d put this to them to check.
And I would think similiarly on your last question in that you’re not using margin if your next trade doesn’t exceed $4,800 and you’re not holding trades overnight using your firm’s credit.
But I’ve not beein in your boat so I’d definitely ring a broker up and find an account manager or rep you can talk it through with.
