How EZRate calculates its rates
EZRate rates are extracted from real buy and sell messages in trading groups and channels — never copied from other websites. This page explains exactly how each number is built.
Every 60 seconds EZRate collects the rates quoted across dozens of trading sources, drops quotes more than ±1% away from the median, and publishes the weighted median of the rest. If fewer than 5 valid sources exist, the previous rate is kept and labelled “low-source”.
1. Data pipeline
2. Outlier removal & median
First we take the raw median of all quotes. Any quote further than the allowed tolerance from it is dropped. From the remaining quotes we record the weighted median (weight = source reliability). Try moving the tolerance:
3. Sources by asset
4. Gold formula & coin bubble
gold_18k = gram_24k × 0.750 · 21k × 0.875 · 22k × 0.9167
mesghal = gold_18k × 4.3318
bubble = coin_market − coin_intrinsic
The global ounce is the live spot price of gold. The formula price is compared with gold-trader groups and flagged when the gap is large.
5. Adjustment factor
To stay aligned with the market an admin can apply a small factor: final = base × (1 + k%). Every change is recorded with time and admin name in the audit log and announced on this page.
6. Limitations
- Rates are quoted prices, not settled trades, and may differ from your local exchange.
- During quiet hours (nights, holidays) fewer sources are active and rates update more slowly.
- Global currencies are derived from the global source’s daily data.
