Even limit orders may serve the exact purposes that you are looking for, I would like to be cautious against ever changing market conditions so that you may not get trapped by all of sudden volatility. When you are placing orders market may seem like in your favour but when you move away from the market then anything could happen which might lead you to lose your capital.

If you are preferring to trade with the help of limit orders and then you must choose non-news hours as market may not show much volatility in such hours. Still, wild fluctuations may happen at any time hence placing stop-loss order at the time of placing entry order is also most mandatory one to secure your capital.
