Sometimes, during very illiquid periods, the markets can gap significantly. Any orders placed at prices with no quotes will be filled at the next available price. This may result in opening the trade at a less favourable price. Slippage can occur at any time but is mostly relevant during periods of high volatility when market orders are executed. This can also happen when a large market order is executed, but there isn’t enough volume at the chosen price to execute the trade at the current market price. Slippage can occur when there is a delay between the trade being ordered and when it’s completed. Therefore, First Frontier does not guarantee to pay the profit for trades where significant slippages occur on First Frontier’s corporate trading account.
