Relative strength comparative in metastock can be drawn from the above like all other indicators
Alternatively, in data downloader do file new composite, write a name for composite say Ranbaxy-n(for nifty or sensex), click primary and put Ranbaxy, click secondary and put nifty, sensex or the industry indice
In the operation put divide and then do ok.
You can go back to see the chart in metastock.
The problem here is that although on doing edit databy right clicking you can even get the open,high, low and close of the composite, the metastock exploer does not accept composite securities with the result it becomes impossible to get all the closes in one shot if you were using the daily closes explorer. In one shot one can know how well all the securities are performing vis-a-vis the index. Getting individual charts or figures maybe good but is cumbersome.
Anyone on how to know the comparatives in one shot. This is very important as one has to know which stock is over or underperforming.
As far as volatility is concerned, one can use the stdev function but the issue is what periods to put in. I think from a day trading perspective, 3,5,7 days would do just fine because beyond that it becomes both impractical and values also differ greatly.
