i'm using CalculateOrderQuantity to calculate the quantity available according to my margin availability. It seems to be providing the correct results according to Oanda calculator https://www.oanda.com/forex-trading/analysis/currency-units-calculator yet Oanda provide some hard limits for symbols. For example, for Platinum symbol orders cannot have more than 500 units, and my margin permit orders with higher quantities.

Do you know where to retrieve the order limits for each symbol?
