Library "LibraryTimeframeHelper" Helper functions to work with timeframes: to get the next higher TF, and to make the string pretty for use in labels. Perhaps I'll add more later.
f_getHigherTF(_TF) f_getHigherTF(): Converts the input timeframe into the next one up in the list of commonly used timeframes. NOTE: You can NOT use a TF from this function as input to a request.security() call if called from this library because it gets converted to a series (since there's nothing special about this function, I expect this probably goes for any library). However, you CAN copy the code and use it directly in your script, in which case the output is only a simple variable and thus suitable for the timeframe of a request.security() call. Parameters: _TF (string) - The timeframe to convert. Returns: : A string in standard timeframe format.
f_prettifyTF(_TF) f_prettifyTF(): Converts the input timeframe from standard timeframe format to the format shown by TradingView on a chart. The output is not suitable for use as an input timeframe of a request.security() call. Parameters: _TF (string) - The timeframe to convert. Returns: : A string in prettified timeframe format.
NOTE: If you want to use the output from the first function as input to a request.security() call, you need to copy the function into your script and change this line:
export f_getHigherTF(string _TF)
to this:
f_getHigherTF(_TF)
For some reason, typifying the input (which is mandatory in a library but only optional in a script) breaks it.
