The Negative Balance Question.

Has you experience the account gone negative as by Margin Call, does your broker required you to fill up the debt?

Or you just change Broker and ignore the debt.

If you got few accounts hold in that Broker, will they just deduct from your other account or from your reserve balance and so on...

You can easily go Margin Call if the broker spread suddenly become 1000 pips rite?

Usually we accept this possibility when signing the contract, but in fact is a very rare event because stop out of all brokers is set with safety margin to prevent this problem;
However, to be validated eventual spike or movement must be present on the official quotes....in january, a fake spike on alpari caused a debt of more than 1M on one of my real accounts, but obviously it was a problem on their server and the balance was immediately restored.

I didn't aware of such contract.
<<< That we need to settle the debt if there is really a big spike and cause margin call result negative balance >>
If broker able to prevent this then there should no sort of this contract to be exist rite?

The contract is digitally sign or Paper one?

Yes, indeed it is so, because the mediator is required to apply any technological measure to prevent this, so it is almost always a doubt clause in the contract and if the broker insists, remains the complaint.....but broker asks you this?

An example of this 'doubt' disclaimers:

Oh... boy, most EA we use did not has Close All Function when balance low and wait till Margin Call.

So definitely trader will just change Broker and left over the debt if this happened.

Even at leverage 1:200 , you can get -123.56%. So law suite can not happened rite if the Broker is different country with you.
In some country Forex is not legalized by the Government, can broker still cross country to get legal firm to chase back money.
Like this case, I invest 50k, then turn out I still owe them 62k.
