"The single lot trades are usually done by the institutions to see who's on the other end of the trade."

I didn't say for sure I said apparently unless you can offer me a better reason

If an institution has access to name of buyer or seller I can see an advantage sell 1 share every now and then if you see TM or a bank on buy reciept you buy up before market announcement or vice versa if you see steve hunt has sold ie you bought 1 share and see SH on receipt you can dump before announcement he has... not sure if or how that data is available to brokers but logically makes sense and explains 1 or very small share trades.....certainly an advantage..if you saw top 20 on sell would be concerning....
