We derive every displayed price from three independent inputs.
1. Spot price The international spot price of gold (XAU/USD) is collected from health-ranked providers. Failed providers are demoted automatically until they recover.
2. Foreign exchange FX rates are collected from independent providers. We use USD-based exchange rates and apply the current validated rate for the selected currency.
3. Local price Local values are computed inside the application:
- Convert USD-per-troy-ounce into per-gram
- Multiply by the standardized purity factor (24K = 0.9999, 22K = 0.9167, 21K = 0.8750, 18K = 0.7500, 14K = 0.5833, 10K = 0.4167)
- Multiply by the target weight (gram, tola, ounce, kilogram, baht…)
- Convert into the local currency at the current FX rate
Every figure is a pure spot-derived value. Local retail prices in shops include dealer premium, VAT/GST and — for jewellery — making charges on top of this base.
