Normally all the solutions are here.

The maximum volume that an account has the right is can be crossed. I do not know the details, but if you put all the checks present in the page you have a very solid control.

Volume Limit Reached - Validation for new Expert Advisor error

Fernando Carreiro, 2022.07.22 18:22

Your EA must be coded to read the broker's contract specifications, such volume limitations, and prevent that from happening.

SYMBOL_VOLUME_MIN	Minimal volume for a deal	double
SYMBOL_VOLUME_MAX	Maximal volume for a deal	double
SYMBOL_VOLUME_STEP	Minimal volume change step for deal execution	double
SYMBOL_VOLUME_LIMIT	Maximum allowed aggregate volume of an open position and pending orders in one direction (buy or sell) for the symbol. For example, with the limitation of 5 lots, you can have an open buy position with the volume of 5 lots and place a pending order Sell Limit with the volume of 5 lots. But in this case you cannot place a Buy Limit pending order (since the total volume in one direction will exceed the limitation) or place Sell Limit with the volume more than 5 lots.	double

Hi,

"The maximum volume that an account has the right is can be crossed."

I don't understand this sentence, what do you mean?

Hi,

I checked that my overall symbol volume limit is 0.0

How to increase my volume limit?

Looking forward for your respond.

Thank you,

D.

Some brokers have the limit set at 0.0, I assume that this means that there is no limit from the broker.

Your broker may set it at 0.0, but other brokers won't. (The validation tester obviously sets a limit)

In your function to check the limit, you should check whether the limit is 0.0 and act accordingly.

Thank you so much Keith!

Because of your explanation, I finally able to pass the validation tester!

Indeed,0.0 means there is no limit from the broker! That's mean we need to create a function to act accordingly for those broker that sets a limit. 

Appreciate that.

Please write here what you wrote after SYMBOL_VOLUME_MAX); ?

I am having the same problem with my EA

[Svetoslav Ognyano Chilingirov]

This problem was frustrating...

But this thread actually helped me understand what the issue is.

This was my fix:

         if(SymbolInfoDouble(Symbol(), SYMBOL_VOLUME_LIMIT) != 0) {

            if(lots > SymbolInfoDouble(Symbol(), SYMBOL_VOLUME_LIMIT)) return 0;

           }

In my broker SymbolInfoDouble(Symbol(), SYMBOL_VOLUME_LIMIT) is equal to 0.0. So if it's not my broker and if the lots I'm about to enter a trade with are more than the SYMBOL_VOLUME_LIMIT (of the tested broker) -> don't enter!

Thank you for the explanation folks.
