I traded Research In Motion Limited (USA) (NASDAQ: RIMM) today and got jacked by my stop order. There are a few things that I learned from this experience that I want to pass on to help others avoid getting burned by this in the future.
A bit of background: I’m working out an alternate trading arrangement with my Zecco account money, so today I traded through my TD Ameritrade account. TD offers “streaming” data, and this data and my stop order are the subject of my wrath today.
The Setup
I wanted to scalp RIMM as it broke yesterday’s swing low. It broke through quickly, without giving me a good entry spot. Price rebounded, and then went down again, so I now had an area for my stop:

The Trigger
Went short as price made a new low, filled at $208.52, and I placed my stop at $209.10, safely(?) above the prior swing high at $209.04.
Trade Management
Price retraced after my entry, and I was watching the Time and Sales, but price never hit my stop. Then it moved in my favor and went down big, about 2R:

I noticed my P&L indicator wasn’t changing, and then realized that they had sent through my stop order, and I was filled back at $209.0894 for a 1R loss. Here’s a closeup of the price chart (supplied by TD Ameritrade streaming data:)

The Screwing
I tried to figure out WTF was going on. They said I was filled at 09:48:52 ET. I looked back over the TD Ameritrade Time and Sales, and found the place in question:

Only two transactions show during that second, and the highest ask at the time was $209.09, while the best print was $209.05, as my chart showed. I called TD and related what had happened. Their trade resolution department told me that there were “pages and pages” of trades that went through during that second alone. They sent me an excerpt from their records, as follows (only the names have been changed to protect the innocent and shame the guilty):
Mr. Prospectus,

So based on this information alone, I was indeed stopped out, as the national BBO (best bid / offer) did tick to $209.11. Once that happened, my order was sent to the market as a market order, and was filled. If this is all true, then they filled my order as requested, though it still never showed that on the tape or the charts! There is no public record that my buy-to-close order ever took place. That’s what’s got me so steamed. If the chart moved, and I got stopped out on the top tick, then so be it. It happens. But I got taken out “off the record”, or at least the record they publish in the public arena is incomplete.
The Lessons Learned
The first big lesson is that your time and sales, even if it is streaming, does NOT contain all of the transactions that occur out in the marketplace! You don’t have anywhere near all of the data, nor do you have any idea where the BBO really is now or where it has been. Your chart is also incomplete. There is a quoted market, but there are a lot of transactions that take place outside or inside of what prints on a chart or on the tape. So when you see a big block go through on your T&S? Could have been 1000 small orders all taking place within a second, just like this print was for me today. I also have no way of knowing if TD themselves bumped up the offer momentarily, using it as an excuse to “sell” me the shares, and then buying them back off the open market at a lower price. Was there a broker physically sitting there screwing me on purpose? No way–my order doesn’t matter. Could they have computer algorithms programmed to do this kind of thing automatically? Absolutely possible, and easy arbitrage money. Don’t treat your data or your chart as gospel!
Lesson two is that your stop order will be sent to market if the National bid (or offer if you are short) hits your level. It’s not if price trades there, it’s not even if the “bid” or “ask” that you see streamed hits there. The stop is sent if a number you can’t see hits your level, according to your broker’s word alone. I don’t even trust my own mother that much! They can’t get too far off from the publicly quoted numbers, or a lot of people will get really mad. But there are bids, offers, trades, and even probably volume that takes place off the books, so to speak. Beware! Place physical stop orders with your broker at your own peril!
The final lesson is that I should have avoided the $209.10 round number. This is the one thing I could have controlled, and the one area where I made a mistake. I’ll put in my stops away from any even levels from now on, if I use physical stop orders again. I wouldn’t at all, except that I’m afraid that I’d get screwed if I lost my data connection just as I was going to exit a position manually. I guess the problem I had today is a byproduct of having that insurance in place. I suppose it’s better to lose 1R as a fluke than 4R or more. Either way, avoid any kind of round number for your stop!
Trade Summary:
RIMM Short
Entry: $208.52, Stop: $209.10, Target: Scalp (point or two)
Exit: $209.0894, P/L: -0.99R
Trade Grade:

UPDATE: The tick seems real, and my stop order should have filled as it did. The only thing that didn’t perform up to standards was my stop selection and TD’s lousy LI quote feed, which only passes on some of the info in real time.
