New to MKT Buy/Sell question

Add liquidity: Buy at the ASK and Sell at the BID with LMT. Your delay from a retail connection and software (what you see and what is reality) is probably off about 1.5 seconds minimum. Remember the action is round trip (.75 seconds per trip leg) and your reaction is at least .25 seconds.

It may be just a semantic thing, but usually adding liquidity is when your order sit on the book. Buy at the ask usually remove liquidity.

Could be the bid-ask spread and slippage.
If you're running an automated strategy that frequently buys and sells at market, get a co-located server to optimize fills and reduce slippage.

%%
00.80 or .90 slippage still sounds excessive\ not normal, even if its worst fills , semi liquid stuff.
TQQQ sure could do that $1 slippage with market order\fast dropping market; but i would not call that normal+ do use market order exits on tqqq some.
Could probably get worse slippage that that selling close to open., Slippage can be positive also.

I probably stand corrected. I guess it also can be from the buyer or seller perspective?
