How can market volatility affect my orders?
Market volatility can affect your orders in a variety of ways, namely the creation of wide bid-ask spreads and increased slippage. Also, enhanced volatility may cause limit and stop limit orders to go unfilled.
Periods of intense volatility have a greater impact on the fill prices of market and stop market orders. These order types are executed at the best available price, which may vary significantly as volatility intensifies.
