The Laws
All prices are shown in pounds; LSE shares are quoted in pence, so 252p
appears here as 2.52. Scans run automatically on weekdays at 08:00 (market open) and 14:30 (two
hours before the close) London time. The universe is built live from Yahoo's screener:
every GBP-quoted share on the London Stock Exchange, Main Market and AIM, around 1,400
companies, with a static FTSE 100 and 250 list as fallback.
Data comes free from Yahoo Finance and can be delayed or patchy for smaller
LSE names; failed fetches are skipped. The spread rule is proxied by market cap and the
pension deficit check is omitted, as neither is available in free data. This bot paper
trades virtual money only and is not financial advice.
