I checked the listing of brokers in the broker ratings section but I didn't find interbankfx. I was going to add a review as former customer. I'll put it here and if the powers that be see fit they can add it to the brokerage rating section. 80-90% of my experience with InterbankFX was actually good. Metaquotes' trading software worked fine for the trading scripts I intended to write, and all of my orders went through very quickly. Making deposits and withdrawals (well, my final and only withdrawal) was a fast and easy process. Their online chat support also allowed me to get help quickly and easily. Their server reliability left a little wanting, though. A while back they had some problems with their servers going down from what they claimed to be an unexpected influx of customers but they seemed to have taken care of that and my connectivity was fairly dependable. My biggest problem with them came after making what was actually a very successful trade. I installed the software on a new computer and when it downloaded the data the history had been changed for that day. I wouldn't have even noticed if it weren't for the fact that I had that trade in the bank. When I ran the backtesting function on my new computer it didn't show that winning trade, and when I compared the charts for that day on both computers the one that had been on at the time showed different prices than the one that had just downloaded the data. I deleted all of the history from my old computer and sure enough it downloaded the new 'fixed' prices. Needless to say I was pretty stunned. You can probably guess why I've decided not to do business with them anymore. As a systems trader I can now never trust any backtesting results I get using their data, because I can't count on their history to reflect what prices my fills would have actually gone through as. This is more than an issue of just calculating in slippage. This is a potential for fills WAY off the chart.
