Trading212 retains huge spread after slippage?

Im using the demo account to learn more about leveraged forex trade and been playing around with GBP/USD, I keep noticing after slippage there is a huge spread being maintained by Trading212.

For over 10 minutes the spread was between 25-15pips, which seems quite insane. It would only decrease when bid increased.

The ask price doesn’t seem to budge despite bid going down, since I am a bit new to all of this am I missing some vital forex knowledge, or its some sort of manipulation by T212?

That is normal for CFDs at every broker. The higher the volatility the wider the spreads. Watch the upcoming interest rate decision by the FED, spread will be huge for some minutes.
