Dear traders, A new field, xstockMultiplier, has been added to the GET /v5/market/instruments-info AND /v5/account/instruments-info response when category=spot. Note - This field is only meaningful when symbolType=xstocks. For all other symbol types, it returns a default value of "1". - The value reflects cumulative adjustments from corporate actions (dividends, stock splits, reverse splits) on the underlying US equity. - Values may appear as high-precision decimals (e.g., "1.0000658218334353"). This is expected — minor deviations from 1 are caused by accumulated dividend adjustments, not data errors. How to Use You can apply this multiplier to calculate the actual price and quantity of an xStocks token relative to its underlying US stock: - Adjusted Price = xStocks Token Price / xstockMultiplier - Adjusted Quantity = xStocks Token Quantity × xstockMultiplier This is an additive change and will not impact existing integrations.
