Hi Pioupiou .. and KKLL .. and anyone else out there ...
I just wanted to remind us all that despite our multiple expressions of humanity; age, wealth, weight, smarts, language, gender, family, free time etc we are all pretty much in the hands of “the machine” here ...and today’s trading gives classic examples of how two aspects of ‘the machine’ can make coming up with reliable information based on trading statistics a bit difficult ...

As I see it ( and please educate me further if I’m wrong!) ) If HFT is being used on a stock it basically means the same 10 shares can get bought AND sold 100 or even 1000 times a day adding to volume and even value but not really giving any indication of overall liquidity .

At time of photograph, current volume on today’s trading was 904,403 shares via 806 trades.
The image shows more than half that volume went through on one s3XT trade and to me the trading shows classic use show High Frequency Trading Systems (bots) vs ‘secret’ trades made via the ‘dark pool’
In relation to both the link below is most informative especially if statistics are correct. It basically says that there are only ten main agencies responsible for all HFT trades and that back in 2016 47% of all on market trades were HFT. (Representing 27% of equity)
Beyond this “dark liquidity counted for around 25 to 30% of equity turnover
“Of those 57% of the volume is caused by large block trades which is why dark pools originally grew up - to keep big orders secret. Institutions can go to a number of Dark Pools for off market share exchange”
