Stop Loss (ตัดขาดทุน)

A Stop Loss (often written SL) is an order you attach to a trade. If the market moves against you and touches the price you set, your platform closes the trade automatically. Its purpose is to limit how much you can lose on one trade.

Simple example

You buy EURUSD at 1.1000. You decide you are wrong if the price falls to 1.0950, so you place a Stop Loss there.

• Distance to the Stop Loss: 1.1000 − 1.0950 = 0.0050, which is 50 pips.
• Trade size: 0.1 lot (10,000 units). On EURUSD, one pip is worth about $1 at this size.
• Planned loss: about 50 pips × $1 = $50.

If you were selling instead, the Stop Loss would go above your entry price.

Why it matters

A Stop Loss lets you decide your maximum risk before you enter, when you are calm, instead of making emotional choices during a losing trade.

Things to remember

• A Stop Loss is not a perfect guarantee. In fast markets or price gaps, your trade may close at a worse price than you set. This is called slippage.
• A common beginner mistake is trading with no Stop Loss and hoping the price returns.
• Another mistake is moving the Stop Loss further away after the price gets close to it. This increases your loss beyond your original plan.
• Setting it too close to your entry can close the trade on normal small price movements.
