Well, not unheard of...no... but there are several things you all need to know:
#1. Broker's #1 concern is not YOU... it's their wallet...

#2. They will do whatever it takes to line their pockets including pip hunting; non-triggered entry or exit targets; claim computer "fault"... and any other creative marginally legal way they can get your $$...

One of the standard clauses in any agreement includes something about the broker not being held liable for "computer malfunction" or "failure to deliver signal" due to some problem or other. Now some brokers are more honest than others and actually refund part of your $$ IF it was legit electronic fault...others are not so generous. I actually had some $$ refunded by Marketiva because of a electronic glitch of some kind 2 years ago. While I don't hold up Marketiva as a high water mark, they did do the right thing in this instance.
#3. IF broker is losing $$ because their traders are lousy traders... well, they take YOUR $$...

Most brokers offer managed accounts... or so-called managed accounts which are managed by totally incompetent traders with way too little experience to manage anything except their own wallet. So...buyer beware... is always good.
#4. When you go out there to trade... you are on your own. You are in the camp of the enemy... your enemies are (brokers and other traders big and small, in addition to news and other economic or ecological disasters). IF you want to survive...you have to stop treating them like friends and start treating them like what they are... enemies.
The above is not limited to just major brokerages... I have yet to find a totally 100% honest broker and I tried a few...

But as I said at some other time... when $$ are at stake, especially large $$, honest folks are hard to come by. Still, I have to commend the charts of fx-open... they are pretty good insofar as I can see, considering what they have to work with.
Happy trading...
