To select the required instrument, click the Select instrument button in the menu window. 
In the window that opens, enter either a partial or full name of the instrument and choose the required one from the options suggested.
The base name can be used in place of the full name of the futures contract. For example, use RI instead of RIM6. Then, every time TigerюTrade is launched, the current contract will be used; when the chart is displayed, the nearest contracts will be merged.
