Lock eight conditions first
Hold constant location, settlement asset, BTCUSDT perpetual market, direction, notional, maker/taker role, account fee tier and holding horizon. If one differs, do not rank the result.
DZPTO's public comparison uses base reference fees and public funding snapshots. Signed-in VIP levels, promotions and personal discounts cannot be inferred from public data.
A 10,000 USDT teaching comparison
If both base taker fees use 0.05% as the teaching input, round-trip trading fee is 10 USDT on each venue. The difference then comes from funding snapshots captured in the same window, not the brand.
If Binance is +0.01% and OKX +0.015%, a long pays 1 versus 1.5 USDT per interval. After three intervals, teaching totals are 13 and 14.5 USDT. Stale or incomparable snapshots should produce no ranking.
The eight conditions that must be fixed
The hard part of a fair comparison is alignment, not arithmetic. The table lists what must be confirmed identical before any ranking is produced. If one item differs, the two figures do not belong in the same ranking.
The right column says where a mismatch shows up. It is also the debugging order: working down, the first inconsistency usually explains most of the gap.
| Condition to fix | Where a mismatch shows up |
|---|---|
| Location and product access | One venue may not offer the contract at all |
| Settlement asset and contract type | Different formula; not comparable |
| Market (BTCUSDT perpetual) | Fees and funding differ entirely by instrument |
| Direction (long / short) | The sign of funding reverses |
| Notional amount | Every fee scales proportionally |
| Maker / taker role | Round-trip gap reaches 0.06% of notional |
| Account fee tier | Not inferable from public data; check signed in |
| Holding period and settlement count | Funding scales linearly with intervals |
How a funding gap compounds with holding time
Suppose round-trip fees are 10 USDT on both sides, Binance funds at +0.01% and OKX at +0.015%, on a 10,000 USDT position. The per-interval gap is 0.5 USDT, small enough to look like noise.
It repeats every interval. After three intervals the gap is 1.5 USDT; after 21 — roughly a week — it is 10.5 USDT, already a full round trip in fees. After 90 intervals it is 45 USDT, four and a half round trips.
Short and long horizons therefore call for different comparisons. Intraday trading is mostly about fees and execution quality; multi-week positions are mostly about the funding path. One 'which is cheaper' table cannot answer both without misleading one of them.
| Intervals held | Binance @ +0.01% | OKX @ +0.015% | Total cost gap |
|---|---|---|---|
| 3 (~1 day) | 13.00 USDT | 14.50 USDT | 1.50 USDT |
| 21 (~7 days) | 31.00 USDT | 41.50 USDT | 10.50 USDT |
| 90 (~30 days) | 100.00 USDT | 145.00 USDT | 45.00 USDT |
Public numbers versus personal results
A personal comparison must use the fee tier, contract specification and funding path in each signed-in account. If the product is unavailable in one location, a low cost is not executable.
Depth, slippage, availability and risk rules also matter, but subjective scores without a common measurement method should not be inserted into the fee formula.
Separating affiliate relationships
DZPTO calculates under equal conditions first and discloses referral links in a separate block. Commission does not enter fees, source selection or ranking.
Click metrics are for aggregate conversion analysis and must not move a higher-converting venue upward. Users still verify eligibility and official terms.
Official sources and calculation boundary
The three sources cover fee structure and the funding mechanism, but none answers the question that matters most: your actual fee tier once signed in. A public comparison can align the conditions; the rest has to be checked in both accounts.

Frequently asked questions
Why does DZPTO sometimes show no cheaper venue?
When funding data is not equally valid, timestamps are too far apart or only fallback values remain, ranking would create false precision.
Does a referral link change my trading fee?
DZPTO adds no fee to the formula. The venue controls actual rates and promotions; review official terms before registering.
Why does the comparison sometimes show no ranking at all?
Because the data is not comparable. If either funding snapshot is stale or missing, or the two were fetched more than two hours apart, no ranking is produced and each estimate is shown with its state. Ranking snapshots from different moments misleads more than showing no ranking.
Can a public comparison replace checking while signed in?
No. Account fee tier, promotional discounts, product access and regional eligibility cannot be inferred from public data. A public comparison narrows the field and explains the cost structure; the final step still belongs in the order preview of both signed-in accounts.
