Start with the questions that matter.

What does a trade really cost?

Fees, funding, and the cost of holding.

Round-trip fees$8.00
Estimated funding paid$3.00
Estimated net cost$11.00
How this estimate works

Trading fees = notional × fee rate ÷ 100 × 2. Funding = notional × funding rate ÷ 100 × holding hours ÷ interval hours, with the sign reversed for shorts. Positive funding means longs pay shorts. Negative funding reverses the direction.

This is a linear holding-time estimate with constant rates and constant entry/exit notional. Actual funding depends on settlement timing and changing rates. Excludes slippage, price P&L, liquidation, gas, transfer costs, rebates, and builder fees. A negative total represents estimated net fee/funding receipts, not trading profit.
