New to me from cms

you: I did not know that i could have a negative balance in my account
you: with out been stop out
Yanis: this happens on major gaps or volatile price movements
you: but should i be stop out regard less
you: what if i had a stop loss during this time what will have happen
Yanis: I'm sorry for the delay. I'll be right with you.
Yanis: there is weekend slippage which means you get filled at the Sunday open price on your orders
you: explain more, what happen if i have a stoploss
Yanis: CMS Forex honors the price on all stop and limit orders up to 10 lots under normal market conditions. VT Trader is designed so that your market order will never be executed at a price you did not see or approve. If the market has moved away from your asked price, you will be re-quoted. Please note that slippage may occur on stop and limit orders due to weekend price gaps.
you: so you are saying that if I put in a stop loss and it week end and slippage occur my stop is useless

Not completely useless, just moved according to the slippage. This is a risk in Forex, especially if you leave trades on over the weekend.

I notice you have been a member for 5 years. How come you didn't already know this?

Yanis: if there is a gap then the possibility is there

I am see negative balance and I have a stop loss set.

I believe Oanda is one the few brokers that will honor the stop loss as set. From what I have read, I don't see that CMS has done anything wrong. As stated before, gapping over the weekend is added risk when you carry over the weekend.

It sucks, but chalk it up as a learning experience and move on to the next trade.

You have to understand that if price moves from 1.3493 to 1.3624, I'm looking at a MT feed, then the prices between those two numbers never existed. It's the same as if I have a store and I sell a TV on Monday for $300 and you come back on Tuesday I've raised the price to $500. The prices from $301 to $499 never existed and you could not buy the tv at those prices, no matter how much you argue.

When you have a stop loss, and the price gaps over it, you will get filled at the first available price. It's part of the game and you should know this. As mentioned, it's one of the risks of leaving trades open over the weekends when you use a broker that doesn't allow any trading during that time.

Your broker did nothing illegal and you don't have a leg to stand on. Take it as a lesson learned, because that is the only positive thing you can do. Or you can let the negativity sear itself into your mind and cause permanent damage.

Great explanation

Are they any brokers, that does not allow this.

You said one of the risk, could you tell me of other to look out for.

You missed the point. All brokers work this way because this is how the market works. You could use Oanda because they allow you trade during hours most brokers don't. The spread is much wider during these periods, but in your situation, paying an extra 10 pips on the spread would be worth it.

some brokers allow you to set a guaranteed stop but it cost an extra pip or two. I.G markets is one. It is more of a necessity for stocks as they can gap everyday where as forex only closes once per week and even then gapping is moderate compared to the stock market. I am happy to work around forex gaps without the need for guaranteed stops. If your entire account is at risk from such a small move perhaps you should look at your money management rather than the outcome of a single trade due to slippage caused by the weekend gap.
