Which is the spread fee formula in eToro? [closed]

In their official website (in a pdf fees document), the equation they mentioned does not match reality (depending on my practice with their demo trading account), nor logic.

in their pdf file : spread fee = (ask-bid) * number of units * the share price

so If I want to buy one Amazon share (which was 4000 \$ ; ask: 4007, bid: 4000) I assume I would pay 7 * 1 = 7 \$ not 7 * 1 * 4000 = 28000 \$

Is there an unintended mistake in their attached commission file?

• is it possible that they express bid-ask spread in percent (or bp) rather than cents? Also, since you buy at the ask and sell at the bid, I'd expect to pay only half the bid-ask spread, when compared to mid. Apr 27, 2021 at 17:39
• you are correct, that's what I was wrong at. Thank you very much.

• An interesting point, is "eToro" such a scam that questions about it actually should not be allowed on the site? Apr 28, 2021 at 13:14
• @Fattie maybe you could stop calling everything and anything a "scam"... Apr 28, 2021 at 13:42

I don't see where they're defining the formula as `(ask-bid) * number of units * the share price`, I see it defined as `rate * units * price`. If you look at their example, they list a "typical spread rate" of 0.18% for AAPL, which is what they're using in their formula.
