I just used my trading software and brought up a one minute chart for the last 5 days with after hours trades "enabled". It does in fact show a volume traded of 5300 shares at 4:21... so somehow or the other there's another 1000 shares involved.
What I want to find each transaction that happened that day after hours with the time including the seconds. I already have it without the seconds. I need to prove that my order was traded before the other 1000 shares. It seems to be case because on the Nasdaq website they are in order but if I could find a much precise time that would be great.
At 1601 EST the bid dropped to $8.65... that was the best bid. It stayed there through 1621. I think you saw the $8.65 bid and your eyes played tricks on you... you thought you saw $18.65. It happens. When you adjusted your quantity to 4300 to match the bid, you sent the order and you either sent it as a market order....or... when you were adjusting your order quantity, (I have no idea how your software works) it just matched the bid as part of some auto function... and you hit send and got a fill. Perhaps some schmuck realized he just bought 4300 shares, got spooked, and turned around and sold 1000 of them to lighten up as the bid remained at $8.65. That could explain the extra 1000 shares.
On my broker website, the bid that I see is the best bid available and obviously at $18.85 it wasn't from ARCA. After hours, the only option available is limit order.
https://www.nyse.com/publicdocs/nyse/markets/nyse-arca/NYSE Arca Rule 7.10.pdf Page 2 has all the CE parameters. I'm baffled how that trade is still on the tape?? The CLEARLY ERRONEOUS RULES for ARCA exchange state that trade should have been broken. It's not even a question. I have been on both sides of probably two dozen trade breaks for well into 6 figures (cumulative) over the last two decades. This absultely meets all criteria for a break. The brokerage saying it's your entry error is completely irrelevant. That is exactly why there are trade break parameters! I'm betting your BD took the other side of the print and kept your $.
A couple problems I see with this...no market maker would panic and sell and only limit orders are accepted. Can a mm sell to himself? What if he saw the order book with someone trying to offload the shares, sold himself 1000 shares to set the last on the hopes OP's platform would default to the last and OP wouldn't notice the missing "1", and was right?
Or the intent could be to fake an extreme earnings miss...or either or both.... What was the exact minute of the release (and were there trades afterwards)?..and when was the release scheduled? (I.e. Did the above happen at expected while actual call was delayed?)
It's really encouraging to read posts like this. I will have a much better sleep tonight than 2 days ago! Now I need to convince ARCA that it should be cancelled. My broker told me that they called the next morning and ARCA refused to cancel. Is that really a possibility?
I don't know that he has recourse here. The ECN's kind of make after hours different. From the SEC: After-Hours Trading: Understanding the Risks The New York Stock Exchange and the Nasdaq Stock Market—the highest volume market centers in the U.S. today—have traditionally been open for business from 9:30 a.m. to 4:00 p.m. Eastern Time. Although trading outside that window—or "after-hours" trading—has occurred for some time, it used to be limited mostly to high net worth investors and institutional investors. But that changed by the end of the last century. Some smaller exchanges now offer extended hours. And, with the rise of Electronic Communications Networks, or ECNs, everyday individual investors can gain access to the after-hours markets. Before you decide to trade after-hours, you need to educate yourself about the differences between regular and extended trading hours, especially the risks. You should consult your broker and read any disclosure documents on this option. Check your broker's website for available information on trading after-hours. As with trading during regular hours, the services offered by brokers during extended hours vary. You should therefore shop around to find the firm that best suits your trading needs. While after-hours trading presents investing opportunities, there are also the following risks for those who want to participate: Inability to See or Act Upon Quotes. Some firms only allow investors to view quotes from the one trading system the firm uses for after-hours trading. Check with your broker to see whether your firm's system will permit you to access other quotes on other ECNs. But remember that just because you can get quotes on another ECN does not necessary mean you will be able to trade based on those quotes. You need to ask your firm if it will route your order for execution to the other ECN. If you are limited to the quotes within one system, you may not be able to complete a trade, even with a willing investor, at a different trading system. Lack of Liquidity. Liquidity refers to your ability to convert stock into cash. That ability depends on the existence of buyers and sellers and how easy it is to complete a trade. During regular trading hours, buyers and sellers of most stocks can trade readily with one another. During after-hours, there may be less trading volume for some stocks, making it more difficult to execute some of your trades. Some stocks may not trade at all during extended hours. Larger Quote Spreads. Less trading activity could also mean wider spreads between the bid and ask prices. As a result, you may find it more difficult to get your order executed or to get as favorable a price as you could have during regular market hours. Price Volatility. For stocks with limited trading activity, you may find greater price fluctuations than you would have seen during regular trading hours. News stories announced after-hours may have greater impacts on stock prices. Uncertain Prices. The prices of some stocks traded during the after-hours session may not reflect the prices of those stocks during regular hours, either at the end of the regular trading session or upon the opening of regular trading the next business day. Bias Toward Limit Orders. Many electronic trading systems currently accept only limit orders, where you must enter a price at which you would like your order executed. A limit order ensures you will not pay more than the price you entered or sell for less. If the market moves away from your price, your order will not be executed. Check with your broker to see whether orders not executed during the after-hours trading session will be cancelled or whether they will be automatically entered when regular trading hours begin. Similarly, find out if an order you placed during regular hours will carry over to after-hours trading. Competition with Professional Traders. Many of the after-hours traders are professionals with large institutions, such as mutual funds, who may have access to more information than individual investors. Computer Delays. As with online trading, you may encounter during after-hours delays or failures in getting your order executed, including orders to cancel or change your trades. For some after-hours trades, your order will be routed from your brokerage firm to an electronic trading system. If a computer problem exists at your firm, this may prevent or delay your order from reaching the system. If you encounter significant delays, you should call your broker to determine the extent of the problem and what you can to get your order executed.
I wonder if there would be any way for you to replicate this right now while taking a screen recording via software. If there is in fact a glitch, they may try and patch it very quickly, but if you can show this to be the case, you might have something. If the order you submitted was a limit order at 18.85, and the platform somehow removed the 1, or changed it from limit order to market order, then it would in fact be a glitch I imagine. It sounds like your problem is technical, and not with the exchange though because you're saying your broker sent the order wrong, or perhaps I'm still missing something. Edit: I'm still confused about what you mean by changing a cancelled order. What did you cancel? Why were you changing it? And what were you trying to change it to?
