buys are NOT double the sells. This is the most basic tenet of trading - sells are always the same as buys.
What you're doing is looking at the LSE data which is WRONG - it's a guess only based on the mid point of the bid/ask.
If you don't understand this, please don't invest in shares outside of an ETF/fund
