just wanted to double check. im assuming that what i see on one second chart are sell orders being triggered, for example a stock creeps up to .25 cents and right on the dime there is a spike of orders running through. and then stop. am i correct to assume that those are mostly limit orders? whether they are sell or buy? and stop loss would look same but going down price dips momentarily and triggers the stop loss orders and then a wall of orders runs through on tape the next second and chart shows a domino effect to the downside for few seconds at a time. im guessing because of the lag for all the exchanges it happens in increments from each exchange running through their orders in chunks?
The information is of transactions. Buy orders are another's sell and vice versa. More demand price goes up. More supply price goes down.
You might be referring to the "round number" effect. Back in the day, stocks were done in fractions, 1/8th. Then they moved to .01 (pennies). But people still put in orders around round numbers. xx.10, 10.15 etc. So 0.25 is not a surprise. To avoid them you have to add a buffer. I use a multiple of the spread AND a buffer, AND a S/R line AND the most recent relevant price action based on volume. As for limit orders, yes some are probably on the books, but as you should now know, LMT orders don't have to be on the exchange and can be held at the broker. So "if touched" orders are also mixed in: LIT and MIT, which will look the same on the tape.
%% IF you mean a total price of 00.25 that IS callled noise in a penny stock; but super liquid stufflike TQQQ goes up a lot more than $ 00.25+ dimes 777] USING A REAL profit example close to ''round numbers LOL,OK '']; TQQQ limit order on $73.98=actual fill to day $73.9699. exit profit=none of your business.but its seldom a round number, like $74.000, it can be some. I use market order exits about 80% of time SCHW gives real good fills mostly. Many are likely limit orders ,good liquid [non penny stocks]or ETFs some no doubt are market orders like i use.............................. Wisdom is profitable to direct.

Instead of seconds, look at days, weeks or months. Instead of just any equities, look at better quality ones. S&P 500 is a good place to start with. https://www.slickcharts.com/sp500/performance Device a plan of attack e.g. price range vs profitability. Just my 2 cents worth.
