When a position is transferred to the night, (profit/loss) Pnl is not displayed correctly, and entryinto the trade is not displayed. Why is that?

The position price is calculated on the basis of the transactions available in the Quik. When transferring through the night, Quik does not broadcast previous day's trades (if the Quik was closed after the opening of the deal). Therefore, the position price and the PnL are not calculated.
