How to calculate StopOut, if the broker expresses it in money, but not in percentage?

[leon_17]

Hi, please, help to understand this issue.

Personally, I myself have not encountered such a situation yet, but it became interesting, because MQL4 seems to make it possible to determine what exactly means a stopout in money or in percent. With percentages, everything is clear and we need to follow the condition:

if(AccountInfoInteger(ACCOUNT_MARGIN_SO_MODE)==ACCOUNT_STOPOUT_MODE_PERCENT)

{
 AccountEquity()/AccountMargin()*100<=AccountStopoutLevel()
}

But what comparison should be made if the level is set in money is not clear

 if(AccountInfoInteger(ACCOUNT_MARGIN_SO_MODE)==ACCOUNT_STOPOUT_MODE_MONEY)

Tell me how to?

p.s. Sorry for my English, I hope I was able to correctly convey the essence of my question.

Stopout means your free margin went negative. See № 5

If you are worried about margin and leverage, you are not controlling your risk. Never risk more than a small percentage of your account, certainly less than 2% per trade, 6% total to the account. Risk depends on your initial stop loss, lot size, and the value of the pair. It does not depend on margin and leverage.

1. You place the stop where it needs to be — where the reason for the trade is no longer valid. E.g. trading a support bounce the stop goes below the support.
2. AccountBalance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot) (Note OOP-OSL includes the spread, and DeltaPerLot is usually around $10/pip but it takes account of the exchange rates of the pair vs. your account currency.)
3. Do NOT use TickValue by itself - DeltaPerLot and verify that MODE_TICKVALUE is returning a value in your deposit currency, as promised by the documentation, or whether it is returning a value in the instrument's base currency.

4. You must normalize lots properly and check against min and max.
5. You must also check FreeMargin to avoid stop out

Most pairs are worth about $10 per PIP. A $5 risk with a (very small) 5 PIP SL is $5/$10/5 or 0.1 Lots maximum.

@William Roeder,  thanks for your reply!

In this case, I am only interested in paragraph 5.

Which code will be correct??

   if(AccountInfoInteger(ACCOUNT_MARGIN_SO_MODE)==ACCOUNT_STOPOUT_MODE_MONEY)
     {
      // Stopout comes when:

      AccountFreeMargin() <= 0;

     }

or

   if(AccountInfoInteger(ACCOUNT_MARGIN_SO_MODE)==ACCOUNT_STOPOUT_MODE_MONEY)
     {
      // Stopout comes when:

      AccountFreeMargin() <= AccountStopoutLevel();

     }

or

   if(AccountInfoInteger(ACCOUNT_MARGIN_SO_MODE)==ACCOUNT_STOPOUT_MODE_MONEY)
     {
      // Stopout comes when:

      AccountEquity() <= AccountStopoutLevel();
     }

Did I understand correctly that the second option would be correct?

Stopout comes when: AccountFreeMargin() <= AccountStopoutLevel();

p.s. The terminal shows that free margin can be negative without a stopout
