For Market Orders, the execution price may differ from the price you expect.
This is because a Market Order is executed immediately at the best available prices in the order book at the time the order is placed. If your order quantity exceeds the available liquidity at the best price, the remaining portion of the order will be filled at the next available price levels, resulting in slippage.
The degree of slippage depends on market liquidity and your order size at the time the order is placed. Lower market liquidity or larger order sizes are more likely to result in greater slippage.
