Fast answer
Crypto signal maker/taker checks connect order type to cost and fill realism.
Before accepting a maker/taker fee assumption, record venue, fee tier, order type, market or limit behavior, post-only setting, timestamp, spread, missed-fill labels, partial fills, and final result.
If a provider counts a trade as filled without showing whether it used maker or taker execution, fee assumptions and fill realism are incomplete.
Order-type checks
What to inspect in crypto signal maker/taker fee records.
Taker execution
Marketable orders usually fill faster, but can pay taker fees and accept worse price during fast markets.
Maker execution
Limit orders can reduce costs or earn better pricing, but may sit unfilled while price moves away.
Post-only labels
Post-only settings can help avoid taker fees, but cancelled orders should not be counted as successful fills.
Partial fills
A result sheet should label partial fills instead of treating the full target size as executed.
Source context
Maker/taker models separate liquidity-adding and liquidity-taking orders.
Binance Academy explains that exchanges using maker/taker pricing often charge lower fees to makers because makers provide liquidity. Kraken says a taker fee applies when an order matches immediately against the order book, and post-only can keep an order on the maker side or cancel it. Signal reviews should connect these mechanics to fill evidence.
Review standard
A reviewable maker/taker assumption shows whether the trade actually filled.
For CSR evidence review, maker/taker fee records should include original alerts, venue, order type, post-only setting, fee tier, expected cost, fill timestamp, partial-fill status, missed-fill labels, and final close record.
