EMA30 price on chart does not match EMA30 price returned by converter API

[TtomaS7]

There appears to be a discrepancy between the EMA30 DOT price displayed on the Subscan chart and the EMA30 price returned by the DOT converter / API.

For the same timestamp (2025-11-10), the values differ noticeably.

What should be the same?

• EMA30 on the chart
• EMA30 returned by the DOT converter endpoint

But right now, they are not aligned, which results in incorrect financial calculations for ecosystem grants and payment flows that rely on EMA pricing.
