PharmaCyte Biotech Inc (PMCB)

[Triple9]

High frequency/program trading. Some believe traders send signals to each other via bid/ask and size, but I think there's usually a reason for an odd size.

I recall seeing batches of $PMCB shares in 499 lots, which seems weird but when multiplied by the order price was nearly $30 exactly.

So I think that was someone tinkering with designing and developing a new program trading system- literally someone testing their trading system in a live, but low risk environment (PMCB is a fairly stable penny stock)- before using it with real money.
