Features are added by the user inside the `populate_any_indicators()` method of the strategy
by prepending indicators with `%` and labels are added by prepending `&`.
There are some important components/structures that the user *must* include when building their feature set.
As shown below, `with self.freqai.lock:` must be used to ensure thread safety - especially when using third
party libraries for indicator construction such as TA-lib.
Another structure to consider is the location of the labels at the bottom of the example function (below `if set_generalized_indicators:`).
This is where the user will add single features and labels to their feature set to avoid duplication from
various configuration parameters which multiply the feature set such as `include_timeframes`.
