5 Old School Trading Sayings That Still Hold Up Today

Markets change, but trader psychology doesn’t — and these timeless adages prove it.

Good morning,
​
Markets change.
Tech evolves.
​(Imagine telling Jesse Livermore about ChatGPT… “yeah, so there’s this device in your pocket that knows everything right, and…”)
​
​
But some old-school trading sayings?
Well, they stick around for a reason.
​
Here are 5 classic adages that still hold weight today…

TRADING ADAGES

📈 “Strong stocks close strong.”
​
​
Don’t overthink it. If a market holds highs all day and closes near the high, there’s usually follow-through coming. The strength is telling you something… Hold.
​
🧨 “Don’t short a dull market.”
​
​
Sideways, quiet sessions are a trap for short sellers. Without urgency, price often just grinds higher and wrecks your patience. Shorts thrive in momo.
​
🕰 “Amateurs open the market, pros close it.”
​
​
Sure, it’s mostly algos now, but the close still matters.
It’s where the auction ends, the final agreed price… and the one that makes the headlines.
​
🔄 “Cut your losers fast, let your winners run.”
​
​
Cliché? Yes.
Ignored by 90% of traders? Also yes.
But it’s still one of the most important rules in the game.
​
🫣 “The market can stay irrational longer than you can stay solvent.”
​
​
Thinking you’re smarter than price is the fastest path to pain. Ride the wave, don’t fight the tide.
​
Old traders knew the score…
​“The markets may change, but human nature never does.”
​
​
Very true, gentlemen. Very true.
