Can broker move stocks against daytraders?

[Don White]

The easy solution, if you are day trading and the market has no strong bias, take no position
or keep the position very small or the powers that be will have the incentive to move against us.

Walter my broker is Interactive Brokers, I have the same suspicions that you have. I would like to know how much information IB shares with those who are taking the other side of my trades those dark pools, market makers and others who are paying IB for a first look.Too often I have accumulated a large amount of shares in AAPL or VRX and the share price moves down, if I then sell those shares say 2000 to 5000 shares, the share price will immediately reverse and start going up.
I believe Market Makers can often control price movement for minutes and sometimes hours on Lower Volatility stocks to keep day traders who trade in higher volumes out of the money.
I have found the best time for me to trade is the first 20 minutes of the day
after that most stocks can be manipulated by market makers or algos.

If you consider AAPL and VRX "lower volatility" stocks I'd be curious what you consider a higher volatility stock! You do know they both average over 30M shares traded per day. That's over $3 billion dollars a day for AAPL. You seriously think a MM is going to manipulate that kind of volume for hours at a time to get a couple bucks off your 5000 shares?

Yes on days that AAPL & VRX do not have news these stocks open and after the first 30 mins of trade do not move until the market makers algos notice day traders taking a position, at that point the price moves against the day trade to keep the position from being in the money.
I have hundreds of the following screenshots that prove how precise these algos are. In this example I was short TESLA,

the red shaded area is in the money, notice how the market maker keeps the price per share out of the money?
