Finding underlying ticker symbol for indicator

Hi Stinus

When you set up an indicator, you would need to state its ticker/symbol first. In that case, we usually save it in a dictionary for multiple symbol usage. Then we can call the inidcator and its corresponding symbol easily.

# in initialize(self) method
self.SymbolIndicator = {}

# Setting up the indicator
self.SymbolIndicator[symbol] = self.SMA(symbol, period, resolution)

# calling the indicator and its symbol
for sym, ind in self.SymbolIndicator.items():
		symbol = sym			# your symbol needed
		indicator = ind			# your indicator of that symbol

Of course there is an indirect but unstable to call that is not recommended:

# Not recommended
MySMA.Name.split(',')[-1].split('_')[0]
# return a string with ticker name like "SPY"

Cheers

Hi Stinus Hojensbo,
The indicator object does not have an attribute to store the symbol of the asset which is built on. We recommend maintaining a dictionary keyed by symbol to store indicators for the symbol. We have created a demo algorithm that stores indicators created by both shortcut method or custom period indicator. Alternatively, we can also implement a SymbolData class to store multiple indicators for a symbol. Refer to this thread for more information.Best,
