Small time traders can own bots these days so I wouldn't try reading into that (I used to). Also fast says because there is a 1 on the end of a bid it's institutional. Makes me laugh. U see those types of bids often from traders so they can easily recognise there order in a line up (I've done it myself).
Anyway, still getting a good laugh from the diehards, thinking patience is the key! imo TIMING is the key!
