Last reviewed: August 14, 2026. Bybit TradFi trading cost is the combination of spread, commission, overnight swap, currency conversion, and execution effects. The exact amount depends on the instrument, session, account, region, and holding period.
Affiliate and risk disclosure: ByDITT is independent from Bybit. BYBITDC is an affiliate code and may compensate ByDITT. It does not guarantee “immediate cashback,” a payback, or a TradFi fee reduction. Check the registration display, account fee page, and live instrument specification.
The four costs to calculate
| Cost | When it appears | Where to verify |
|---|---|---|
| Spread | On entry and exit through the bid/ask difference | Live executable quote |
| Commission | On a trade according to the product’s charging rule | Instrument specification and account history |
| Swap / overnight financing | When a position crosses the product’s rollover time | Info panel, direction-specific swap and schedule |
| Conversion and execution | When currencies differ or the market moves during execution | Quote preview, fill price and account conversion record |
Bybit’s TradFi Fees Explained says commission and swap vary by product. A swap can be charged daily, and a three-day swap can apply on a specified day. Never apply one instrument’s cost to another symbol.
Spread
The spread is the difference between the executable buy and sell price. It can widen around session opens, closes, news, thin liquidity, holidays, and overnight periods. A “zero commission” label does not make the trade free when the spread is wider.
- Record the bid and ask immediately before entry.
- Use the contract’s tick value, not a generic forex formula.
- Repeat the calculation for the expected exit session.
- Add slippage for stop orders, news, gaps, and fast markets.
Commission
Commission can be based on lot, notional, side, or another product rule. The current rate should be taken from the symbol’s Info or Specification panel and confirmed in the executed trade history. A referral-code article cannot override the account record.
Overnight swap
Swap can differ for long and short positions. It is applied at the instrument’s rollover time, not simply at your local midnight. Daylight-saving changes and server time matter. Bybit’s official fee page explains that a three-day swap can be charged to account for non-trading days.
- Check the long and short swap separately.
- Confirm the rollover timestamp and server time zone.
- Identify the three-day swap day for the exact symbol.
- Count every rollover the planned holding period crosses.
- Recheck before holidays and special market schedules.
Trading hours affect cost
TradFi instruments do not all trade 24/7. Bybit documents 24/5 trading for selected US Stock CFDs, while other products have their own sessions and daily breaks. A displayed price outside the underlying market’s primary session may have different liquidity and spread.
Use Bybit’s contract specifications and the live Info panel to verify trading hours, contract size, tick value, margin, and swap.
A total-cost worksheet
- Select the exact account and symbol.
- Record contract size, tick value, and quote currency.
- Capture the live bid/ask during the intended entry session.
- Record commission and both swap directions.
- Count expected rollover events, including any three-day charge.
- Set a conservative exit spread and slippage allowance.
- Convert the total into both quote currency and a percentage of planned margin.
- After trading, compare the estimate with the account history.
Short trade versus overnight position
| Holding plan | Costs that usually dominate | Main check |
|---|---|---|
| Intraday | Spread, commission, slippage | Liquidity and news during entry/exit |
| One or more overnights | Spread, commission, daily swap | Rollover time and long/short swap |
| Across weekend or holiday | Swap schedule and gap risk | Three-day charge, close/open session and stop slippage |
| High leverage | Same cost becomes large relative to margin | Notional, MMR and liquidation distance |
Referral code claims
BYBITDC may be recorded on an eligible account, but it does not by itself prove a commission reduction or cashback for TradFi. Verify any displayed benefit during registration and the actual fee record. Do not describe an affiliate commission paid to the referrer as a rebate paid to the trader.
Risk controls
- Size positions from maximum acceptable loss, not available leverage.
- Allow for gaps through session breaks and weekends.
- Do not hold only to “earn back” commission or swap.
- Keep margin above the minimum required for the planned volatility.
- Recheck product terms after platform updates.
- Save screenshots of the specification and cost history for tax and audit records.
