Why do I keep getting harassed about using market orders? I'm getting warnings, alerts, checkboxes, squeeze pages... all sorts of friction and warnings alerting me to the horrible dangers of market orders. I feel like they're pushing me with everything they have to use limit orders, which makes me even more suspicious.
I generally do not use or like limit orders, for the following reason:

That's how it works. Regular investors, the suckers using those stupid limit orders, buy high and sell low, all the time. [pg 55]
Scott Patterson said:
If we have sufficient depth behind our order at a given price level, then we are effectively self-insured against losing money. Why? If we get elected on our order, we could immediately exit our risk for a scratch by trading against one of the orders behind us.[pg 53]
Scott Patterson said:
In other words, if the 0+ trader buys a stock (gets "elected"), and his algos suddenly detect that that price is likely to fall--they can see a large number of sell orders stacking up in the queue--he can flip and sell to the sucker standing behind him, resulting in a "scratch" (no gain and no loss). He can do this because his computer systems can "rect fast enough to changing market conditions... to 'always achieve, in the worst-case, a scratch or a cancel of our orders." [pg 53]
I would much rather take a small loss buying at market price, than to be a sucker.
Furthermore, like most things in life, there are pros and cons. Market orders offer an advantage: if I manually break up my orders into bite-sized pieces, and buy at the market price, I can see the price fluctuations to my buys and sells in the bid/ask spread. This way, I won't take any huge losses if the market is a bit soft; I can keep testing until I see more resistance, and then amp up my trading.
There's also something fundamentally honest about market orders. It's the most basic exchange. It goes all the way back to Genesis, when Joseph was sold to the Ishmaelites for 20 silver pieces. They paid the price, and got their product. They didn't put a limit order on him, they sold him at market price.
Genesis 37:28 said:
Midianite traders passed by, and they pulled Joseph up out of the cistern. They sold Joseph for twenty pieces of silver, to the Ishmaelites, who took him to Egypt."

Now that's leveraging a market opportunity, eh? Next time you find a guy at the bottom of a well, you know what to do.
Perhaps most importantly, there I find:
truth. Hallelujah!
