Missing symbols for XTB broker

Hello everyone,
I just started using this application recently and I have some questions:

  1. On XTB platform, there is ETF named VUAA.UK but I cannot find this symbol on Yahoo Finance or other data provider, the best similar one I can find on Yahoo Finance is VUAA.L, should I use this instead?
  2. PP seems to calculate profit based on “Close” prices of stocks/ETF, is there any option to make it calculate based on Bid/Ask price instead?
  3. How to add a trade with use of margin?
    Thank you for your support!

Everything after the dot act as a stock exchange identifier.

So in the first step, you need to define currency and stock exchange.
Afterwards to can make use of all sides which do provide quotes and a “readable” for PP. Within PP you distinguish between historical quotes and recent quotes.

How this is being done can be found here:
