Before updating the platform to the new version, we recommend that you perform the Commit operation to send all local changes to the MQL5 Storage.Note: the USDEUR and USDGBP pairs are used in the source dollar index formula.Therefore, you will need to perform a checkout of all data from the storage after the platform update.Data stored at the MQL5 Storage will not be lost or affected during the update.Also, all symbols required for the synthetic price calculation are automatically added to the Market Watch.An entry about the calculation start will be added to the platform journal: Synthetic Symbol USDX: processing started. ten times per second) the prices of symbols used in calculation are checked.For example, if the calculation formula is EURUSD*GBPUSD, the price of the synthetic symbol will be calculated as follows: The availability of changes is checked separately for each price.
Unsupported terminal builds will not be able to connect to new server versions.
High, Low and Close prices are calculated in a similar way.
If the required bar is not available for any of the instruments, the platform will use the Close price of the previous bar.
Since only reverse pairs are available in the platform, a negative power and Ask instead of Bid are used in the synthetic symbol formula.
The platform will calculate in real time the price of the new instrument based on the quotes of the other six symbols provided by your broker.
