With regards to your concern, two things come to mind
A) you should probably understand stock screening better. If stocks are on edge of 33% debt/equity ratio stock price swings will have an impact. If the debt ratios are well within the threshold, then you won’t have an issue during your trading time frame.
B) perhaps you should use some software or make a spreadsheet of halal stocks with their values that you are interested in and keep an eye on a subset of the market.
I won’t comment on day trading itself as I don’t have clarity about it. Swing is probably less contentious as the trade completes before selling.
