Methodology & Data Notes

CoinNavigator shows spreads by comparing prices across exchanges, and highlights prediction markets by attention (24h volume) from Polymarket. This page explains where the data comes from, how spreads are computed, and what can go wrong (fees, slippage, delays).

Data sources

Spreads come from public exchange APIs (ticker/price endpoints). We select the best observed buy/sell venues per asset and compute the spread.

  • Exchange prices: third-party APIs (availability and rate-limits vary).
  • Polymarket: market metadata + YES/NO prices used as implied probabilities.
  • Region handling: internal links may include a region parameter to show context-first recommendations.

How spreads are calculated

For each asset, we compare observed prices across venues and compute:

spread% = (bestSell - bestBuy) / bestBuy

Important: this is a gross signal. Your net result depends on fees, slippage, withdrawals, and time-to-transfer.

Known limitations

  • Fees: maker/taker, withdrawal, deposit, and network fees can erase a spread.
  • Slippage: the price you get may differ from the ticker price.
  • Latency: prices move fast; spreads can disappear before execution.
  • Transfer time: moving assets between venues can take minutes to hours.
  • Partial outages: an exchange API can fail or block requests temporarily.

Always verify on the exchange UI and read the risk notes in Terms.

Polymarket notes

We sort markets by 24h volume to surface what’s attracting attention. YES/NO prices are shown as implied probability and are informational only.

  • Freshness: the “hot events” file is typically refreshed daily.
  • Interpretation: a probability reflects market consensus, not certainty.
  • Risk: prediction markets involve risk; do your own research.
