This tool is a DLL library that can be used from any trading development application, such as MetaTrader and TradeStation.

Installation & Demofiles

Installation may vary by application. DLL files must be placed in an application’s DLL include path or the Windows’ DLL include path; for example, the 64-bit shared library include path is %windir%\SysWOW64. In MetaTrader4 (builds 0600 and below), the library path is %MetaTrader4%\experts\libraries. In TradeStation, the include path is %TSPATH%\Program\.

You may need to enable DLL execution because it's sometimes disabled by default (for security reasons). This tool was released as a DLL, so you’ll need to enable DLL Execution.

Functions

bool LogAdd(str Line)

This function adds a line to LogViewer. It also shows the LogViewer window whether it’s closed or it’s called for the first time. Nearly all settings are saved in the registry and will be restored on each new view. Returns “true” if successful

bool LogAddColor(str Line,int Color)

This function has the same behavior as LogAdd(). Output color can also be defined. Color constants are the same as web constants. This integer value represents RGB in hex; for example, white is defined as 0xFFFFFF, black as 0x000000, and maroon as 0x800000. You can refer to the Internet for more RGB color combinations.

Refer to the help files of your particular development software in order to determine supported color constants.

TradeStation doesn’t know the content for maroon. We already know the hex value of maroon (0x800000), so we can simply convert it to dec. In dec, it’s 128

Useful link about color constants is here. See the "Access" column for decimal values.

bool LogClear()

Use this function to delete all LogViewer lines. Please note that this function will also delete lines that were added from other studies. Returns “true” if successful.

bool LogMarkString(str Mark)

Strings marked with this function can be changed. To disable marking, empty the string. Returns “true” if successful.
