Yet another fraud: http://www.forextraders.com/forex-broker-tips/questionable-forex-broker-practices-explained.html " Excessive Slippage Slippage occurs when an order, usually a stop loss, is not executed by a forex broker at the rate at which it was placed. Instead, the order is filled at a rate that is usually worse than originally intended by the trader. Some order slippage might be acceptable in fast markets when exchange rates change rapidly, but in an orderly market they might represent yet another way for a forex broker to make extra money off of its clients. "
Never been called naive before, guess there's a first time for everything. Here's how it works. If you are accusing someone of a fraud, you don't get to just say that you can't explain how it works but they're real smart so just trust that they're able to pull it off, and if you don't think so you're naive. Also, "google it" doesn't make your point. I could say "Barack Obama planned 9/11, google it" and that doesn't make it true....sorry, you're not one of the people who actually believe that are you? You need to show how they could pull it off, and how a well prepared, non-naive person couldn't take advantage of their manipulation. Re-quoting and slippage aren't going to work for them. As long as there is a two way market and I can put in limit buy and sell orders, as you can with every regulated U.S. broker, they can't manipulate the quote feed without me taking advantage of them. Again, the OP isn't talking about a Cyprus forex bucket shop here. They don't have to be so subtle about taking your money, they just don't respond to your withdrawal requests! The OP was talking about U.S. based stock brokers and stocks like AAPL.
I too am talking of US brokers. And, yes indeed I do believe some brokers are doing this, I've had that suspicion myself, the OP has it too, and many other people (one just needs to research on the net). You are talking of efficient market hypothesis, ie. of no arbitrage. Just re-read how Re-quoting works, then you can drop that theoretical possibility of advantage you talk of.
Which brokers, which stocks? Just because a bunch of people lose money on stocks, blame their broker, and post about it on the interwebs don't make it so my friend. Talk about naivety. I'm very familiar with what re-quoting is (and I could discuss market efficiency with you for hours, are you referring to strong form, weak form, or "you don't know what I'm talking about because you don't really have any idea what efficient market hypothesis is, but you heard the phrase somewhere and thought it makes you sound smart" form?). It doesn't allow a broker to provide out of market fake quotes and not get taken advantage of by me or anyone like me. Please please please give us details on who is doing this and under what circumstances, I want to take advantage of it! I'm guessing this information isn't forthcoming because it doesn't exist, but happy to be proven wrong.
I'm not crazy to tell you, a stranger to me, the name of the broker. You have your naive believings based on theory, and the rest has his own based on practical experience...
I'm confused, you think a broker is dishonestly manipulating price feeds but you can't tell me who they are because I'm a stranger? Are you trying to protect the broker...who is allegedly ripping you off? Do you think by telling me the name of the broker this stranger is going to break into your house and steal your TV? I'm just not following the logic of you not being able to print the name of a broker because I'm a stranger? And I'm practically begging to practically try out this strategy, all you need to do is provide the name. How again does that make me someone with "naive believings based on theory"? You seemed pretty bullish on your personal version of the efficient market theory before, now you're all about "practical experience"?
Discussion is moving to deep philosophy. Let's back to the practice. Please, anyone who daytrades stocks with 5000 shares or more in one positions at stocks like AAPL, FB or other one, please share your experience. Did you faced with some unknown tendencies?
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.
