Stop loss — why it's not optional

A stop loss is an order that automatically closes your trade if price moves against you past a level you set in advance.

Without one, a single bad trade has no limit on how much it can cost you. With one, the absolute worst case is known before you even enter — which means you can actually plan around it.

A lot of beginners skip the stop loss, thinking they'll "watch it closely" instead. Real life doesn't work that way — you'll be asleep, at work, or your network will drop, exactly when it matters most.

Where you place a stop loss should come from the chart's structure, not from how much you're emotionally willing to lose. A stop placed too tight, just to keep the dollar risk small, often gets clipped by completely normal price noise before the real move even happens — meaning you were technically right about direction but still lost, purely from a badly placed stop.

Trailing stops are worth knowing about once the basics are solid: instead of a fixed stop, it moves up automatically as a winning trade moves in your favour, locking in more profit as the trade develops. It's a tool for protecting a winner, not a replacement for having a real initial stop loss on every trade.
