There is no price impact for trades on VIX, so you can execute large trades exactly at the mark price. During times of high volatility there may be a spread from the Pyth price to the median price of reference exchanges.

The mark prices are displayed next to the market name, long positions will be opened at the higher price and closed at the lower price while short positions will be opened at the lower price and closed at the higher price.

The chart will indicate the average of the two mark prices.
