Result per $1 spent

50 largest wallets, last 5 minutes+3.0¢ per $1

Everyone else, last 5 minutes−0.9¢ per $1

Everyone else, first 5 minutes−0.3¢ per $1

The win rate counts positions; the result per $1 is weighted by the money spent, so the two don't convert into each other directly.

Methodology

How these numbers are made

These figures cover every wallet trading these markets on Polymarket. They are not CandleOdds' own results; CandleOdds' signal record is on the Track record page.
Source: Polymarket's public data.
Only the 15-minute Bitcoin and Ethereum Up/Down markets are counted. A wallet's trades in any other market are left out.
Results are after fees.
The period is Oct 19 – Oct 25, 2026 in US Eastern time; this report was generated on October 26, 2026.
Weekly and monthly figures aren't directly comparable: shorter periods look milder.
"Top 50 by dollars in" can include wallets that mint and merge pairs of tokens rather than trade.
The copy-trading and top-50 sections are in the monthly reports only: one week is too small a sample for them.
