Unit 3 · Level 4 · Perpetuals & Funding
Funding rates: the market's mood meter
Funding usually settles every 8 hours. Positive funding: perp trades above spot, longs pay shorts. The crowd is leaning bullish and PAYING for the privilege. Negative: shorts pay longs. Funding is simultaneously a COST on your position and a live SENTIMENT gauge nobody can fake.
Free to play. No ads, no token, no account needed to start.
What you get asked
Funding is +0.05% per 8h and you're long. What happens three times a day?
That's ≈0.15%/day, over 4% monthly on the POSITION (multiply by your leverage for the hit to margin). Holding crowded longs is expensive rent. Count it in your R:R like any fee.
Funding spikes to extreme positive levels during a euphoric pump. History says this often precedes…
Extreme funding = everyone on one side of the boat, paying to stay there. You learned crowd dynamics with narratives and squeezes; funding puts a NUMBER on the crowding.
Match the funding reading to the trained interpretation
Contrarians read extremes; position-holders read costs. Both readings come free with every perp dashboard.
Some traders farm the 'cash and carry': long spot, short the perp, and collect ___ with no price exposure.
The delta-neutral basis trade: a real yield source you can now EXPLAIN (remember the sacred question). Institutional crypto's bread and butter in bull markets.
You hold a leveraged perp long through a month of +0.03%/8h funding, and price goes nowhere. Your P&L?
Flat price, bleeding position. Perps have theta-like rent when you're on the crowded side. 'Right about direction, dead by costs': the fees lesson from League 1, graduated. 🐜
