Wow.... like the flies! What's that buying pressure on Havelock? Do you think it's merely the chance of buying some cheap shares due to the decrease in BTC price? Or again inside knowledge from Board members or industry partners like we've seen with the announcement of the successful BE300s tests?

A board member wouldn't risk (or care, they have thousands of shares) buying a hundred or two of shares on Havelock based on inside knowledge. Maybe some guy at packaging, or assembly, or something.
But definitely, that buying before the BE300s tests must have been on inside knowledge.

Yeah that was very strange, I mean it happened literally 1 or 2 days before the announcement and the chips weren't supposed to arrive for another week or so, so it couldn't have been pure anticipation I guess.

There is a bot on Havelock that does some market-making, and it occasionally juggles its position from the buy side to the sell side and vice-versa. There is even speculation that it buys/sells into itself to manipulate prices.

You can see the market-making in action by placing a sell order lower than the current ask price, or a buy order higher than the current bid price - even by 1 satoshi. Within a minute, the order that you covered in the orderbook will be canceled and replaced with a new order that differs from yours by about 1 satoshi.

You can see that the market maker is also the whale that moves shares back and forth by looking at the timestamps on bids/asks in the orderbook. Do you think it's just a coincidence that the 250 share bid order and the bid order at the spread were both placed within the same minute?

If you watch the orderbook you can pick out other behaviors that point to a lot of the orders on both sides of the book being controlled by the same party. For example, the bot won't over-bid or under-ask itself, and it maintains open orders at several different bid/ask prices. You can put in a bid in the middle of the book and slowly increment it, then watch which orders keep following yours, then cancel yours and watch the follower drop back down to its initial bid, even though you may have outbid a couple other orders on the way - the bot doesn't care to bid over those orders, most likely because those bids are also orders belonging to the bot.

You can totally scalp off the bot
