What is the average execution price of an order?

The average price in this context refers to the weighted average price at which your order was executed.

Since this is a sell limit order (Limit Order / Sell), and it was executed at 100%, this means that your sell order for BTC at the price you specified or better was fully satisfied.

In the line "Avg./ Price" there are two prices listed: 94461.52 / 94399.1.

94461.52 is likely the price you requested or the best price at which part or all of the transaction was made.

94399.1 is most likely the actual average price at which your entire order was executed. It may differ from the requested price if the order was executed in parts at different prices within your limit.

Thus, the average price (94399.1 USDT) shows the average price at which your cryptocurrency BTC was ultimately sold.
