I've just had an interesting discussion with live chat on my CMC Markets platform. I executed a trade at a busy time and I had Boundaries set (this is the max amount of slippage you will allow) at 15 points, well I was correct with my direction but got a warning come up with "Order rejected. Price no longer valid". I thought this strange as I was watching price and there was no reasoning for this. After chatting for a few minutes I started to dig deeper, and the CMC representative admitted to me that CMC over ride all traders Boundaries settings to their own at around busy news times. Now, mine was set at 15 (quite small, but OK through research) and the representative admitted to me that their setting was less than mine so got triggered and I got thrown out of the trade as a result. Now I'm wondering if this is legal? CMC can manipulate your settings at will.
How can you trust them? The CMC representative kept trying to get me on the phone, but I prefer to keep matters like this in writing for obvious reasons - I'm glad I did - what a wake up call!
