Understanding Discrepancies in Screener Results

[Hiddenleaf07]

Recently, I deployed PK Screener on GitHub Codespaces. However, I've noticed slight discrepancies between its results and those shared in the public channel, even after testing post-market hours. I'm getting extra results compared to the public channel.

@Hiddenleaf07 - That's most likely because many a times for some of the tickers, we get empty datasets. So, those tickers get ignored, especially during market hours. Post market-hours, the download job runs and saves all tickers' data in a pickle, but even during that download job, if we received empty data for those tickers, the results will still vary even after running post-market-hours. This happens most frequently because we hit HTTP 429 status codes (rate-limits). From your local machine, when you request, you may receive data for those missing stocks because your IP was not rate-limited.
I hope this helps.
