Why are my daily BTC purchases executed for 4% higher price?

I have day by day buy orders for BTC and ETH by way of Binance, and I observed the buy worth for yesterday was $117096 when the worth was nearer to $113,500. Why is that this occurring?

Edit: after some analysis and ChatGPT, it’s almost definitely as a result of I used to be utilizing Binance Auto Purchase, the place Binance makes use of conversions relatively than market buys. On most market buys, slippage, unfold and worth impression exposure can amount to fractions of a penny up to some cents, on small buys that is. On conversions, Binance can use any charge rates they want. Subsequently, utilizing the auto buy function for every day small buys was amounting giant %’s of loss. I switched to every day guide market buys, and obtained my loss right down to a penny and half per purchase, versus 10 or even 11% loss. Loopy the way you’re penalized for utilizing the auto buy!
