Pyth Pro: EMA Price and Confidence Fields Now Available

Announcements
1

We have introduced two new fields to the Pyth Pro price payload for Spot feeds: emaPrice and emaConfidence. These fields deliver Exponential Moving Average (EMA) values, offering a refined, smoothed perspective on price and confidence metrics.

New Fields

Field Type Description
emaPrice i64 (optional, non-zero) Exponential moving average of the price, expressed as a mantissa.
emaConfidence i64 (optional, positive) Exponential moving average of the confidence, expressed as a mantissa.

Both fields share the same exponent as the standard price field:

decimal_ema_price = emaPrice × 10^exponent

Availability

These fields are optional—they appear only if explicitly requested in your subscription configuration. Existing integrations remain entirely unaffected.
