Mainly this indicator is a Relative strength indicator which tells us about the strength of a scrip as compared to an index . That is it outperforming the index or underperforming . Outperformance signifies Strength and Under performance signifies Weakness .Inspired from Bharat trader's Relative Strength of a stock , but changing the period for all time frames is a hassle so i have set 10 period for Monthly and 52 period for Weekly. As for monthly we need around 10 months data or we can use 12 as 1 year has 12 months but 10 works best . used 52 period for Weekly time frame because there are 52 weeks in a year. These values are by default dynamically applied to the indicator when weekly or monthly timeframes are chosen . Daily Period can be chosen as per anyone's need . As can be seen in provided screenshot , that the stock has recently started gaining strength on weekly a compared to Small cap100 index . So we can conclude that it has more strength than the overall index it is representing so more chances of outperformance will be there.
