ACM has been a perfect broker to me.
Yeah, a lot of these posts are dated (that is, OLD), but I am still just very perplexed by some of them.
Their customer service to me has been perfect, they have always been available, helpful, and accomodating. I have NEVER had slippage or requotes and have ALWAYS gotten the price I clicked on.
I use them to trade, but out of force of habit, always follow the prices and charts at another brokerage based in the US and highly regarded (I've used them for years, too). If ever there is a difference in price, ACM's is consistently better, but usually they are very close... even exactly the same most of the time.
I cannot speak to others' experiences, I cannot answer the accusations of falsifying positive reviews by a (now) ex-employee, I do know that the "police raid" posts are inaccurate.
Check me out ...my location, my IP, my website, give me a call, write me an e-mail... I am NOT writing on ACM's behalf, they do not know I am reviewing them, they have never asked me for a testimonial, etc., but I am just speaking to my own very positive experiences. I haven't even done that in the normal place (that is, under the broker reviews section)... but maybe I will at some point.
