Hi Everyone, I've been lurking in these forums for a long time, soaking up everyone's comments and knowledge, and I love this forum. Even as a new trader, I have always known never to use a market order, as I heard the broker, specialist, etc can manipulate the price and give you a horrible fill. Nonetheless, while I was merrily scalping dollar/yen, and I saw a good opportunity and the price was moving very fast, so I used it. (my limit order was not filling even after 30 sec) Well, I was trading about 1mil units, and the price I got was something like 106.95 when the pair was 105.88. I was immediately down 10k, wiping away a 6k profit. My question, do I have any recourse at all with my broker? If not, what can I do? I use interactive brokers. Thanks for the help, really appreciate it.
