A few days ago the following filter was posted and it struck me that it might not be delivering the specific results that the user was hoping for so below I've provided some comments that might be pertinent. In any case it always pays to look at several charts to see if you are getting what you expect.
1. This filter was designed to find specific stocks that dropped the least in the recent late winter market drop and it uses a series of set functions looking for values that occurred over a prior 30 day period.
a. It uses a specific offset number of days which means that any user will have to change that offset value if they want to cover the same timespan in the past as the day the filter was posted.
There is a way to set that date offset so it never would have to be changed, by using the following statement:
offset 3/24/2020
b. That filter appears to be also looking for stocks below $2 with specific average volume criteria but these are limiting the filter to those stocks that only meet those criteria at the end of the 30 day period not the beginning of the 30 day period which could effect results. Look at MFAs chart to get an idea of what I mean.
c. I believe Market Cap is one of the SF indicators that does not have access to historical values so it will only find stocks that meet the most recent Market Cap criteria which may exclude some that met it back in Feb.
d. If you examine the chart of SWN, which is about the 4th stock returned in the result list, you'll see that the stock really did not dip as much from early Feb, as it's results position would indicate, due to the fact that it had a mid March spike in price which affected the 30 day high being used by the Set statements.
Another possible way to look at the possible dips on an SF chart and results is to add the following Max Drawdown lines to the filter, a side benefit is you actually get specific max dd line drawn on the price chart:
add column Maxdd(30)
draw Maxdd(30)
