Foreign currency exchange ratio for this position on this date
Notes
If Currency was specified and the current symbol does not trade in that base currency and the needed FX conversion symbol was also imported then FxRatio will report the current currency conversion ratio for this position on this date.
If any of the above conditions is not true then FxRatio will simply return 1.
Since RealTest manages currency conversions at position entry and exit and adjusts daily mark-to-market position values by FX ratio, it's usually not necessary to use this ratio variable in your strategy formulas.
One case where FxRatio may be useful is in a Quantity formula when QtyType is Shares. That quantity type is interpreted verbatim. Quantity: 10 means buy (or sell) 10 shares (or contracts), regardless of the instrument's currency. If you want to calculate a share quantity and then FX-adjust it then divide it by FxRatio.
