Confirmation of momentum
If you expect the direction of price movements to tend to an uptrend after breaking the resistance level then you can open a Buy Stop order a few pips above that level. And vice versa if you estimate the direction of the price will tend to downtrend then you can open Sell Stop orders a few pips below the support level. These resistance levels and support determine the momentum of the next price movement.
Opening a Stop Order means that you have confirmed your position in accordance with the momentum of the price movement that will occur. You can also determine the stop loss level and target according to the risk / reward ratio that you have planned. As long as the order has not been executed, you can change the level entry or cancel it.
Don't have to continuously monitor price movements
By using this Stop Order or Pending Order, you do not have to monitor price movements continuously to wait for trading signals. However, this method is only used if you are aiming for a breakout condition at the resistance level or support. If you happen to trade by relying on setup price action formation, you must monitor price movements even though not often, because usually price action traders use a high time frame (daily or 4-hour), and valid price action setup formation does not always occur at the level resistance or support.
Prevent over trading
By not always monitoring the market, you will avoid over-trading due to excessive market analysis. From the experience of over-trading traders tend to cause losses due to less valid trading signals (false signals).
Improve discipline
By opening a Stop Order you give a market opportunity to work. The Stop Order will make your entry in accordance with the price level you predicted. Once you have succeeded with a Stop Order, you will tend to use it for the next trade, thereby increasing your discipline in trading.
