I’ve been trading for over three decades now, and if there’s one thing I’ve learned, it’s this…

Most traders don’t have a losing-trade problem — they have a staying-in-bad-trades problem.

The market will hand you setups all day long. Some work, some don’t. That’s trading. But what separates the pros from the perpetual strugglers is knowing when to pull the plug and understanding why the trade was right or wrong in the first place.

One of the fastest ways to sharpen that awareness is by documenting your trades. When you take every trade, save the screenshot and note the timestamp, you create a feedback loop. Reviewing those decisions later lets you see patterns you would never notice in real time.

That kind of reflection builds the discipline needed to follow the rule I use on every scalp trade…

The 20-minute rule.

For those who don’t know, a scalp is simply a quick trade you don’t plan to be in long.

If It’s Not Working in 20 Minutes, It’s Not Working

Once I enter a trade, I want the stock to start proving itself within 20 minutes. If it doesn’t, I’m out. No negotiating with myself. No hoping it will suddenly turn. Just get out.

This isn’t about watching each candle tick by tick. It’s about the general behavior. Is the market still aligned with the trade? Is the stock moving your way even if slowly? Or is it printing high-volume candles against you?

Sometimes a stock consolidates in a strong trend — that’s fine. Other times it consolidates while momentum fades. That’s your warning.

The decision process is simple. After 20 minutes, ask yourself…

If this setup appeared right now, would I still take it? If the answer is yes, stay in. If the answer is no, exit without hesitation. You can always reenter when conditions improve.

This single rule keeps you from giving oxygen to trades that never had real potential. It forces you into a cleaner, more disciplined rhythm — a cornerstone of consistent scalp trading.

Looking for Reasons NOT to Trade

This ties into a bigger philosophy: I don’t look for reasons to stay in trades. I look for reasons not to. If I can’t find any reason not to take a trade, that’s when I take it. And if I can’t find a strong reason to stay in a trade, I don’t stay in it.

This mindset shift alone can transform your performance. One of my students just proved it. He started by breaking even on his first 100 trades.

Then his profit factor jumped to 2.2. What changed? He standardized his position sizes, followed the 20-minute rule and documented every trade so he could see what he was doing right and wrong.

Those habits compounded into mastery.

Your own performance will improve the same way. With time, you’ll become at least twice as good when you follow disciplined rules like these. The rest comes down to repetition, review and refusing to stay in trades that no longer deserve your money.

Set a timer. Keep a journal. Give each trade 20 minutes to prove itself. If it doesn’t, cut it and move on. The market always offers another opportunity.

I hope that helps!
