composite_ticker_cleaner_extract_first(symbol, keepexchange)
Extract the first symbol out of the supplied string (usually ticker.standard(syminfo.tickerid) )
Parameters:

keepexchange : bool (optional) Keep exchange in the returned ticker? By default, we only return the symbol without the exchange.

composite_ticker_cleaner_extract_first(keepexchange)
Extract the first symbol out of the current tickerid (as provided by ticker.standard(syminfo.tickerid) )
Parameters:

Returns: first occurrence of a symbol in the current tickerid
This is inspired by the work I did on this indicator:
I needed a similar functionality in another script, so instead of duplicating code, I thought generalizing the process in a library could be helpful for me and others, and will be easier to maintain and upgrade with new features if I need to.
