Simple scan for all stocks in the past 4 years where they went below 1$ at some time in history
Simple scan for all stocks in the past 4 years that went below 1$ at some point in history,
there is a quote "Our adjusted historical price data cannot be used to determine the actual buy or sell price for a stock at some point in the past." because of reverse splits and similar adjustments
What scan can I use to scan through non adjusted historical price data?
However, as far as I know, the scan engine does not accommodate unadjusted data. You could verify that with Support.
Your scan would use the min( ) function. You would need to determine the number of trading days in four years, which would be roughly 251 x 4, or 1004, or the number of trading weeks or months. Then you need to decide whether you want a close below 1 or a low below 1. Assuming a close and daily trading, it would be
and [min(1004, close) <1]
weekly would be
and [weekly min(208, weekly close) < 1]
Adjusted data lowers past prices (usually), so some results might not actually have traded below a dollar at the time. You should be able to check that using the symbol with underscore.
