The Trades Your Algorithm Rejects May Be the Most Important Data You Never Measure

Grade Bbullish AI signal$ETH

A new research framework highlights a major blind spot in algorithmic crypto trading: rejected trade signals may contain critical information that conventional performance tracking misses. Post-Rejection Follow-up Sampling (PRFS) analyzed approximately 67,000 forward observations across 2,997 rejection events involving 457 unique token mints, while the RED-2400 benchmark aims to make rejected trading decisions measurable. Systematic tracking of rejected signals could improve strategy evaluation, expose selection bias and help developers avoid deploying strategies whose apparent profitability fails under more realistic conditions.

Bullish strength: 55/100

PRFS provides a framework for measuring outcomes after rejected trade signals.
Independent developers are implementing rejection tracking to evaluate screening rules.
Post-rejection analysis could expose selection bias and improve trading-system evaluation.

Bearish strength: 45/100

Historical strategy performance may be distorted by selection and survivorship bias.
Apparently profitable strategies may fail after realistic transaction costs and broader evaluation.
The article does not establish that PRFS or RED-2400 improves live trading profitability.

Ethereum delays Glamsterdam test after security devs flag risk to existing contracts

Ethereum developers have postponed the Glamsterdam upgrade on the Hoodi testnet after security researchers identified potential changes to how existing smart contracts handle failed transactions. The concerns center on EIP-8037 and EIP-8038, which could alter gas accounting and cause some contract operations to succeed or fail differently under the proposed rules; no replacement date has been announced. The delay could pressure short-term sentiment around ETH and Ethereum's upgrade timeline, although developers say the findings do not indicate that existing contracts are currently being exploited.

Ethereum Spot ETFs Post $111M Net Outflow as ETHA Loses $75.45M

Ethereum spot ETFs recorded a total net outflow of $111 million on October 22, based on SoSoValue data. BlackRock's ETHA posted the largest single-day withdrawal, with net outflows of $75.45 million. Fidelity's FETH was the largest daily inflow recipient, adding $2.37 million. FETH's historical cumulative net inflows stand at $2.36 billion, while ETHA's historical cumulative net inflows total $12.26 billion. As of the report, total net asset value across Ethereum spot ETFs was $14.57 billion. The ETFs' net asset ratio, measured against Ethereum's total market capitalization, was 5.01%, and cumulative historical net inflows across the products reached $12.72 billion.

Highlight Clip: Arthur Hayes: HYPE Could Significantly Underperform ETH and ZEC

Arthur Hayes warns that Hyperliquid's HYPE token could significantly underperform ETH and ZEC as competition intensifies and the perpetual DEX sector becomes a crowded consensus trade. Hayes acknowledged Hyperliquid's genuine market demand but said its investment risk-reward appeal has declined, and he previously disclosed selling all his HYPE and NEAR holdings. HYPE could face relative performance pressure if competition increases and investors favor alternative crypto assets, though Hayes's track record warrants caution when interpreting his forecasts.

Bitcoin, gold trim early losses as yen gives up gains. Oil stays near $100

Bitcoin and gold pared early losses as the Japanese yen surrendered its gains, while Asian stocks and Nasdaq futures also recovered. Bitcoin rebounded toward $82,000 after dipping below $81,000, while gold recovered to $4,020 per ounce and WTI crude remained near $100; U.S. spot Bitcoin ETFs recorded $381 million in outflows on Thursday. Persistent oil prices and weak spot Bitcoin ETF demand could limit a sustained crypto recovery, while renewed inflation concerns may continue to pressure risk assets.
