How is the Profit/Loss in Performance Summary calculated?

[iPittyTheFool]

I'm currently analyzing my Activity Statement, especially the Realized Performance Summary and I came across some Profit/Loss positions I just cannot explain.

For example I bought BLX on serveal occasions and had one sell:

Date # Price Fees Eur/Usd Rate
2017-08-25 100 Buy 26.6692 1.0000 1.1874
2018-02-12 50 Buy 27.7650 1.0000 1.2263
2018-09-10 50 Buy 20.7550 1.0000 1.1603
2018-11-12 100 Buy 17.7050 1.0000 1.1240
2018-12-21 100 Buy 17.5000 0.0000 1.1399
2019-03-15 100 Buy 20.0000 0.0000 1.1334
2019-04-18 100 Sell 20.0000 0.0000 1.1251

The base currency of my account is in Euro, therefore the exchange rate of the respective dates.

Moreover I bought the last two positions via puts and the sell was executed by a covered call:

Expiration Strike Premium Fees
2018-12-21 Put 17.5000 40.00 0.29
2019-03-15 Put 20.0000 25.00 0.24
2019-04-18 Call 20.0000 65.00 0.34

In the Performance Summary however I see a loss of -537.11 EURO.

I tried calculating the profit/loss using different methods: first-in-first-out, last-in-last-out and the average price. I also tried including the premiums of the options. No matter how I do the math, I just don't come up with that amount.

Can anyone tell my how the calculations are done?

Find this out *before* you trade, not after.

If you're not sure (or to provide some proof-of-concept), hit the paper-trade.

NEVER use a live account to pose questions you can't afford to answer with bad news.

You completely misunderstood my question. I'm absolutely content with all trades I've done.
Moreover my position with BLX is doing pretty well (especially including all the dividends and premiums).

What I don't understand is how IB is calculating the profit/loss values. For example, if I use the first-in-first-out method, I'd take these two trades:

2017-08-25 100 Buy 26.6692 1.0000 1.1874
2019-04-18 100 Sell 20.0000 0.0000 1.1251

P/L = (sell-price) - (buy-price)
= (20*100)/1.1251 - (26.6692*100 + 1)/1.1874
= 1777.6197 - 2246.8586
= -469,2389

Not even near the -537,11. Same thing with the average price:

Average buy price per share in EURO = 18.3017

P/L = (sell-price) - (avg-price * 100)
= 1777.6197 - (18.3017 * 100)
= -52,5503

The difference is even worse.

To sum it up again: I have no problem with my trades. All I want to know is the formula, that IB is using to calculate the P/L statements. In detail:
What buy price is taken into account?
What currency conversion rate should I take?
Do I have to consider the premiums of the options that were executed?
etc.
