One of the improvements will require minor source code changes when you upgrade to Version 12.6 of Investor/RT and build with the latest irtsdk.h SDK. The CPEN data type in Version 12.5 RTX is a C structure containing a pen color, pen width and pen style setting.

Click (or right-click) the hot spot and a menu of the elements in the pane appears. The visible instruments and indicators in the menu are checkmarked. Elements listed without a checkmark are presently hidden. Each chart element has its own submenu for selecting, editing, deleting, or revising the visibility state of the element.

Version 12.3 now offers an alternative connection method for direct connectivity of Investor/RT to OEC market data and order execution. The direct method works in an integrated fashion with OEC enabled trading DOM execution software such as OEC Trader, and S5 Trader.
