Stop Losses: Where to Place Them and Why They Matter

A stop loss is a standing instruction to exit a losing position if the price hits a certain level. If you buy a stock at 500 rupees and place a stop loss at 450, you are saying: if this drops to 450, sell immediately, even if I am not watching. Stop losses turn a potentially unlimited loss into a defined, manageable one.

Stop losses should be placed based on price action, not on a fixed percentage or on how much loss you can 'tolerate.' For a swing trade in an uptrend, you might place a stop just below the recent support level—if price breaks that support, the structure has changed and the trade is no longer valid. For a breakout trade, you might place a stop below the base that was broken. The stop loss placement defines your thesis: if price reaches that level, you were wrong about what you thought would happen.

Traders often ignore or move their stop losses when they feel emotionally attached to a position. This is how small losses become large ones. A 5% loss that should have been taken turns into a 25% loss because the trader kept hoping it would bounce back. Discipline here is not negotiable if you want to survive long enough to get good at this.

Trailing stop losses are useful in trending markets—they are a stop that moves up (in an uptrend) as the price makes new highs, locking in profit while giving the trend room to run. If you buy a stock at 500 and it rises to 550, a trailing stop might be set 30 rupees below the current price (at 520). As it rises to 600, the trailing stop moves up to 570. This way you profit from the move but are protected if momentum reverses.

• A stop loss defines your thesis and caps your risk.
• Place stops based on price structure, not on how much loss feels acceptable.
• Honoring your stop loss is as important as entering the trade.
• The traders who survive are those who took small losses. The ones who blow up are those who turned small losses into big ones.
