Question 1

What is funding and who pays it?

Accepted Answer

On a perpetual future, funding is a small payment exchanged between longs and shorts every few hours (usually every 8) to keep the contract price near spot. When funding is positive, longs pay shorts; when negative, shorts pay longs. It is charged on your full notional, not your margin, so it adds up faster than it looks.

Question 2

Does funding matter for a short trade?

Accepted Answer

For a fast scalp, barely — one funding window is small. But for positions held across many windows it compounds: the same rate charged three times a day, day after day, can eclipse your unrealised profit. This tool shows exactly when that crossover happens so you can decide whether the hold is still worth it.
