Why does the quote value in a buy change?


I bought a piece of bitcoin and my order got split.

  • Total 20€ worth of bitcoin at 23 235€



Once I save both trade, the price displayed by Portfolio Performance is not 23 235€.

Why ?


Because 6.51 divided by 0.00028 is not 23235, nor is 13.49 divided by 0.00058077.

What does that mean ?
Why is there is a difference ?

PP stores the number of shares and the total price. The rest is calculated from that. And as I said,

Rounding differences.
