Se fai trading di futures perpetui su Binance, probabilmente hai visto qualcosa chiamato commissioni di finanziamento. Molti trader lo ignorano, ma i trader intelligenti lo usano a loro favore.
🔹 Cos'è la commissione di finanziamento?
La commissione di finanziamento è un pagamento periodico scambiato tra trader long e short nei contratti future perpetui. Non è una commissione pagata all'exchange, ma è pagata direttamente tra i trader.
I contratti perpetui non hanno una data di scadenza, quindi le commissioni di finanziamento aiutano a mantenere il prezzo dei futures vicino al prezzo di mercato spot.

Let’s understand how funding works — visually first — and then how to build a low-risk arbitrage model around it.
Why Funding Rate Exists (Visual Understanding)
In perpetual futures, there is no expiry date So exchanges use a funding mechanism to keep the perpetual price close to the spot (underlying) price.

From this visual:

When Perpetual Price > Spot Price → Market is aggressively long → Funding becomes positive
When Perpetual Price < Spot Price → Market is aggressively short → Funding becomes negativeFunding is simply a balancing tool. It incentivizes traders to take the opposite side of crowded positions. 2- The Core Funding Rule (Who Pays Whom?)
Now let’s simplify it completely.

The rule is simple:
If Funding is POSITIVE: Longs pay Shorts If Funding is NEGATIVE: Shorts pay Longs

Formula: Funding Payment = Position Size × Funding Rate

For Example:

$10,000 × 0.2% = $20 per funding interval

On Binance, funding usually occurs every 8 hours (3 times daily).
3- The Funding Arbitrage Strategy (Spot + Futures Hedge)
Now the powerful part. We remove directional exposure and monetize funding imbalance.
Case 1: Funding Is Positive (Most Common) : If funding = +0.15%, +0.20%, +0.30%
This means longs are paying.

Strategy:

Buy asset in Spot
Short same amount in Perpetual Futures
Now your position is market-neutral.

if price rises:

Spot gainsFutures loses

→ Net neutral
If price drops:

Spot losesFutures gains

→ Net neutral
But you collect funding as the short.

You are earning from market imbalance, not direction.

Case 2: Funding Is Negative

If funding = -0.10%, -0.20%

Shorts are paying.

Strategy:

Sell spot (or borrow & sell)Long perpetualNow you collect funding as the long.

This reinforces that funding itself is the income source.
