Price gap in the market opening

How did I get the price from yesterday afternoon buying during the opening today?

If the answer is low liquidity in the market opening, there should be an easy way to avoid it while using Pies and orders done with the market closed. Very unreasonable price doesn’t make sense

Just to be clear. I got prices of yesterday 3pm. So the delta between 3pm and market closing was completely ignored

Have you checked the exchange - you have received the market price when there was liquidity?

The chart in 212 is indicative - it’s the last traded price which can vary wildly between the bid / ask, in particular on less liquid stocks so is not the best to indicate market movement as an inconsistent marker imo.
