Most traders believe their profit or loss comes purely from price movement.

That’s wrong.

There’s a hidden cost — and sometimes a hidden profit — applied to your account every single night, whether you realise it or not. It’s called carry (or rollover), and misunderstanding it is one of the biggest reasons traders fail even with profitable-looking strategies.

In this video, I break down:

• What positive and negative carry actually are
• Why many traders slowly bleed money without noticing
• How professionals use carry as a tailwind instead of a tax
• Why leverage massively amplifies carry (for better or worse)
• How to structure swing trades so time works for you, not against you

If your backtesting looks profitable but your live account doesn’t — this is likely why.

Carry isn’t about replacing trading skill.
It’s about stacking advantages: price, time, structure, and costs.

This is the stuff real traders pay attention to — not flashy apps or fake screenshots.

👇 If this opens your eyes, comment “positive carry” and I’ll break down a real trade example step by step.
