+ | Data Sources are a new feature in Forex Strategy Builder Professional. They allow you to set a different location for the different data you are using as well as to set different Symbols and parameters for each broker. | ||
+ | |||
+ | {{ : | ||
+ | It's a good idea to make a different Data Source for each broker you use. That way you'll not override your previous data and you will be able to change them by changing the Data Source. | ||
+ | |||
+ | {{: | ||
+ | FSB Pro comes with one Data Source preset: "FSB Demo data" and a set of demo historical rates. | ||
+ | You can find the Data Sources page in **Control Panel** -> **Data sources**. | ||
+ | |||
+ | There is a list box with all available Data Sources from the left side of the page. You can change their position by dragging and dropping them in the box. | ||
+ | ===== Data Source Settings ===== | ||
+ | |||
+ | All settings in that page refer to the currently selected Data Source. | ||

+ | **Check data at loading** - when this option is checked, FSB Pro will check data files for several discrepancies. It prints the eventual errors on the " | ||
+ | |||
+ | **Cut off bad data** - when this option is switched on, the program checks for missing data (more than 5 days) and incomplete bars (more than 10 bars with Open = Close). The program will load data starting after the latest gap. | ||
+ | |||
+ | **Cut off Sat and Sun data** - it controls whether FSB Pro loads historical data from Saturday and Sunday. | ||
+ | |||
+ | **Fill in Data Gaps** - forces Forex Strategy Builder Professional to fill in the gaps between bars. It sets a bar Open price to be equal to the previous bar Close price. | ||
+ | |||
+ | **Cache data files** - when it's on, FSB Pro will store data files in a binary format in //Data\Data Cache// folder. FSB Pro loads cached data faster than CSV files. | ||
+ | |||
+ | **Reload Corresponding Files** - this command tells FSB Pro to reload all current data files except those, used in Generator and Optimizer. | ||
+ | |||
+ | **Open Data Directory** - opens the directory in Windows Explorer. | ||
+ | |||
+ | ===== Adding a Data Source ===== | ||
+ | |||
+ | {{: | ||

+ | |||
+ | ===== Deleting a Data Source ===== | ||
+ | |||
+ | The **Delete Data Source...** button, located below the list box, deletes the currently selected item. | ||
+ | Be aware of the following cases: | ||
+ | * You cannot delete "FSB Demo data" data source; | ||
+ | * You cannot delete a Data Source that is currently being used in an open strategy. | ||
+ | |||
+ | When you press the **Delete Data Source...**, | ||

+ | ===== Importing Symbols ===== | ||
+ | |||
+ | {{: | ||
+ | |||
+ | You can import symbols from three different sources by clicking the corresponding " | ||
+ | |||
+ | <wrap hi>The new symbols override the existing symbols with the same name.</ | ||

+ | **Import symbols from** - this tool imports symbols from another Data source. | ||

+ | **Import symbols from " | ||
+ | |||
+ | **Import from MT4 connection** - it imports a symbol from a trader connection. It needs FSB Pro to be connected to MT4 in order to import a symbol. | ||
+ | |||
