Slippage is unavoidable when trading Forex and often occurs during news, high volatility and in market open. Whether you are trading Stocks, Futures, Commodities or Forex, you will be subject to slippage. When you place a market order, you are requesting your order is filled at the current market prices; however, if the market has moved between the time you place your order and the time it has been filled, your order may be filled at a different price. You should keep this in mind when trading outside of normal market conditions.
Stop loss orders, when triggered, enter the market as market orders; therefore, there is no guarantee that your order will be filled at the price you placed your stop loss.
