Does Square intend to address Market botting?

I'm not very familiar with such systems.
With buyorders would buyers set the price and the sellers sell to the ones with the highest buy offer?

Buyers would state "I'm willing to buy X amount of this item at this price per item."
Sellers would decide if they are willing to fill the order.

This isn’t stock market. Buy orders, limits, etc. would just confuse the regular players.

When you go into a store, you look at what’s available and buy an item if you feel both the item and the price are acceptable. Average shoppers wouldn’t want to have research market price and market history (a mere 20 or 30 entries of last transactions, rather than days/months/years) before they decide whether to buy.

It's not that confusing. Other games use buy orders without problem and they incorporate an easy to view/read sales history just as this game does.

If someone is confused by it, they can choose not to use it as regular sell listings would remain.

I played RIFT, which had both buy and sell orders. I rarely used the buy order system directly but I definitely benefited from its existence as the game would match sell orders against buy orders when either was placed. There were plenty of times I would list sell orders at the going market rate just to have it immediately matched to an existing buy order that paid much more than the price I listed.

That system also allowed purchase of partial stacks (it was optional, the seller could opt out and only allow the full stack to be purchased). If someone had 50 listed at a good price but I only needed 10, I could just buy the 10. The remaining 40 would still be for sale to other players.

I know some sellers hate the idea of partial stack purchases but most would end up benefitting because you'd be getting the partial stack sales faster plus it means more listing space available for selling other items. I could list a single 99 stack even though I know players only buy 4-6 of the item at a time with very high frequency while still selling 19 other items/stacks on that retainer instead of having 16 listings of 6 but only room to sell 4 other items. The marketboard is a convenience feature. The more convenient it is for a player to get exactly what they want (without being forced to buy too much), the more they'll buy.
