Yep, algo-trading is a whole new world!
Some of it is "price discovery", i.e. testing whether other MMs are actually trading at the reported bid/offer, some is picking off small amounts left on the bid/offer to nudge the price up or down.
But unless you're also an algo-driven trader using L2 to time trades for small % gains, I would just ignore it.
It is generally good advice to ignore Buys vs Sells too. The only things that really matter are Sales Volume and then, if it's a high volume day, whether the price is going up or down. The rest is just noise.
MMs only make money when people trade, so on low volume days they will shift the bid/offer up or down by a greater margin to try to tempt or scare PIs into buying or selling. Ignore price action on low volume days. By looking at Google, or your portfolio software of choice, it might look like your share is up or (usually) down quite a bit. But if it's a low volume day, the share price isn't indicative of a real market. And this is true of most days, especially on AIM.
There are many PIs who post on message boards, daily, discussing Buys vs Sells. Most likely they are complaining that there are only Buys, or more Buys than Sells, so why hasn't the share price risen? And assuming therefore the MMs are crooked.
Ignore these people, they don't really understand what they are doing or how the market works :)
For successful trading on AIM, buy on low volume days when the price is dropped, and sell at a higher price into volume!
