This setting never changes, and can (and should) be saved in an Analysis Group once for all.
By default, the indicator uses a TF multiplier of 1 (128 bars), so only change it to a number over 256 for TFm = 2 or over 384 for TFm = 3. The indicator will not return an error code if there are not enough bars on your chart, and will just cancel calculations.

As a reminder, SD is the Search Depth parameter (0 for default, 1 for refined in most cases), and Fuzzy Neighbourhood allows finding fuzzy pivots, 1 being 'crisp' and the parameter being generally up to 3 or 4 max.
