Why it is hard
- Gaps blow through stop losses before you can react.
- Correlations break — everything drops together, so diversification stops helping.
- Spike volatility widens spreads and slippage, eroding every edge.
- Panic selling creates false bottoms that trap early buyers.
A practical approach
- Wait for the volatility spike to fade before sizing up — the first move is rarely tradable.
- Trade smaller. Position sizing matters more than direction in a crash.
- Short weakness into rallies rather than chasing the absolute bottom.
- Use wider stops and accept a lower win-rate for a higher reward-to-risk.
Mistakes that blow accounts
- Catching falling knives on the very first gap.
- Going all-in on "the bottom" with no confirmation.
- Ignoring widened spreads that quietly eat your edge.
- Letting one oversized loss turn into a blown account.

Frequently asked questions
Should I buy the dip during a crash?+
Only with a plan. Most crashes have multiple lower lows. Buying in pieces — not all at once — with a pre-defined risk per attempt is far safer than catching the first knife.
Is shorting safer than buying in a crash?+
Neither is safe; both are directional bets. Shorting has uncapped risk and squeeze exposure, so most crash traders prefer smaller sizes, defined risk, and waiting for the volatility spike to subside.
How do I stop revenge-trading a crash?+
Hard rules: a maximum number of trades per day, a maximum loss per day, and a cooldown after consecutive losses. The simulator lets you rehearse all three before they cost you real money.
