What percentage should I set my stop-loss at?

There's no fixed number right for every trade. Set your SL based on *structure* (below swing low/support) or ATR, then adjust *position size* so that the loss if SL is hit = 1–2% of your account. A "fixed %" should only be an additional safety ceiling.

Why does my stop-loss keep getting hit before price reverses?

This usually happens when the SL is placed too close to a structural level or at a round number — where liquidity is 'hunted.' Solutions: add a buffer, use ATR for volatility-adaptive SL, and consider using a close-price SL instead of a touch-price one.

Is a trailing stop better than a fixed stop-loss?

They serve different purposes: a fixed SL protects capital at entry; a trailing stop locks in profits when you're already winning in a trend. Use them together: a structural SL at entry, then switch to trailing when the trade is sufficiently in profit. A too-tight trailing stop can easily shake you out of a position.

Do I need a stop-loss for spot trading?

Yes. Although spot trading doesn't lead to liquidation, a deep loss still breaks the math of recovery and your discipline. An SL keeps each mistake small and controlled, preserving capital for the next opportunity.
