All quotes in the system are sourced from liquidity providers, who have limited transaction volume at specific price points. When you place an order and the transaction volume at the initial price is insufficient, the system will automatically shift to the next available price. This may result in your transaction being executed at a less optimal price. Additionally, the greater the market volatility, the quicker the price changes, increasing the likelihood of such occurrences. We continuously strive to engage robust liquidity providers to enhance the trading experience.
