Your question is why slippage occurs when the stop loss is not in the morning hours? Slippage is due to gaps in market quotations or insufficient liquidity, resulting in a price difference between the final transaction price of a pending order or transaction and the requested price. What you need to pay special attention to is that the changes in market quotations are caused by the mutual power of buyers and sellers, and it is often not continuous. You can notice that a few minutes after the start of 21:30 pm Beijing time on the 19th, the GBPUSD market fluctuates more sharply than usual because of the impact of related news events-Bank of England Deputy Governor Broadbant and Chief Teller Sarah John are following The House Public Appropriations Committee answered questions. We recalled the quotation history at that time in the background, and we can see that the bid price jumped from 1.30043 to 1.30144 at 59 seconds, which just exceeded your stop loss of 1.30073. Because your account is a VIP super spread account, the final execution is 1.30140, which is more conducive to your quotation. 2020.10.19 13:31:59 1.30043 1.30023 2020.10.19 13:31:59 1.30144 1.30124 AvaTrade's orders are fully automated, and all quotations are from banks, and we are committed to providing customers with the highest quality spreads. In normal times, there are very few gaps caused by discontinuous quotations. However, in the extreme market of handover orders and news data releases, the probability of quotation gaps suddenly increases. When there is a gap in the price, if the stop loss price you set happens to be skipped, then slippage will occur because the order cannot be executed at a price that does not exist in the market. In summary, there is no problem with the execution of your order. Hope that the above explanation can help you better understand the potential impact of news events on market fluctuations.
