Most bot trading is aimed at either buying or selling a large parcel of shares without moving the market price by much. And of course, when buying, trying to buy at a lower VWAP (Volume Weighted Average Price) than the current market price is always a bonus. Likewise, selling at a higher VWAP.

So, bot trading (or algorithmic, or DMA (Direct Market Access) trading) is used to move larger quantities of shares, but in multiple tiny numbers. Trickle them out, so to speak.

Unfortunately, it can also be used to manipulate the price by walking the price up or down (that was the problem with all the shorting last year) as well as perpetrating so-called "bunny raids" or stop-loss raids. Walk the price down a step or two at a time until auto-stops get triggered, which then pushes the price down to the next level, and the next lot of stops get triggered, etc etc. A cascading effect, affecting mums and dads, CFD traders, etc.

Then, once the price has bottomed out and no more stops get triggered, the buy-bot starts buying back all the way up to where the price was in the first place. And this whole stop-loss raid and buy-up can occur in a fraction of a second. That's why they call them "high-frequency traders".

And of course, it can only be done by brokers or large funds, with direct market access, otherwise they'd have to pay brokerage on every tiny trade. You and I can't do it.

Hope that all makes sense :)

Not sure what is going on with TOX, but perhaps somebody is accumulating?
