I know the alert feature has been up before (for a long time...).
It would bring a lot of value and I would like to suggest a somewhateasy way to implement it:
In the screeners, add a custom Margin of Safety tab where the user can set his Margin of Safety on any of the Valuation metrics from the Valuation tab (Step 3) for the stocks she is interested in.
Remember a "reset all" button...
If the fair value crosses of either of the MOS thresholds in either direction, the user will get notified via email.
How many users are there on OSV by the way (to pay for features)?
