Funding Rate (Perpetual Futures)

How it works

Unlike traditional futures, perpetuals never expire. To prevent the perp price from drifting away from spot, exchanges charge a funding rate every 8 hours (Binance, Bybit) or hourly (FTX legacy).

• Funding > 0 — perp trades above spot; longs pay shorts to incentivise selling.
• Funding < 0 — perp trades below spot; shorts pay longs.

Why traders watch it

• Crowded longs: very high positive funding (e.g., > +0.05% per 8h) signals over-leveraged longs; squeezes are common.


• Crowded shorts: very negative funding hints at potential short squeeze.


• Funding swings are a leading sentiment gauge — they move before price tops and bottoms in many cases.

How Finvestopia uses funding

On crypto setups in the Radar, extreme funding bias is a soft contrarian filter — we de-emphasise long signals when funding is hot positive and shorts when it's deep negative.

Cost reality

For most traders the dollar amount is small (a $10k position at 0.01% per 8h pays $1 per cycle). What matters is what funding signals about positioning, not the cash flow.
