Just to add my two pennies... there is nothing 'simple' about this new age of trading in the markets today. Algo trading has pretty much taken over, the majority of trades happening (I believe it's > 90% of all trades) are super computers trading against super computers and may the best algo win.

I checked in on some trading house sites and below I will list the types of Algo's available to use if you were to get a trading account with them, it's mind boggling and also a little excessive imo, whatever happened to good old fashion trading based on actual company financials, performance, and projections??

These algos have absolutely nothing to do with companies in any way, they are just looking at raw trade data, in fact they have algos that just make up data so that other algos will think something is happening, it's a whole new world out their, we are most certainly not in Kansas anymore as the saying goes... below is the list, and while it may appear like a long and complete list, those are just the algos developed by one broker, they also had third party algos that you could use which was another list half as long as the one below... I didn't bother posting those, I figured you would get the idea, and I assume other houses also have their own excessive list of algos...

stay safe! (here is the list... it's long)

There's been a huge shift in the past few years to odd-lots, because of technology and slicing of orders by algorithms, as nearly half of all trades on some exchanges are odd lots (also because of the escalating prices of figurehead stocks like TSLA and APPL, people can only buy odd lots like 1 share of Amazon or 5 shares of TSLA).

In fact it used to be that odd-lot quotes weren't even shown on public data feeds, but you can clearly now see small odd lots trades go through.

Maybe it's an allowance for retail traders only, as trading houses I think are still obligated to execute trades at the best price posted on an exchange, with those prices only by round-lot quotes.

Regardless, I did indeed test it out for half a day recently and it was quite surprising to me also.

Maybe others here have similar or contrary experiences. Another fun thing to examine.

You can have a bid of $3.70 and an ask at $3.75 with the last price at $3.75.
10 shares market will NOT move the stocks price from $3.75 to $3.70.

The price will remain at $3.75.

MidtownGuy wrote: Sadly any trade made at the bid price rather than the ask price adjusts the overall price down to that sale price. And it can be done with a trade of 1 share. But traders usually use blocks of 100 share so that they can argue they weren't trying to adjust the price intentionally... and because the system is structured around 100 share blocks which get filled faster than odd numbers and can thus assure the planned price movement.
