is there a variable that is tied to the account number?

[bobo1974]

Hi all,

let's say the value 100 in a variable and that variable is tied to the account number. is that possible?

the reason why i want to do that is because if my mt4 crashed and i need to restart my ea, all the variable value are gone

so if i can somehow store this value that is tied to my account number, then this issue is resolved

any idea?

Account Properties

To obtain information about the current account there are several functions: AccountInfoInteger(), AccountInfoDouble() and AccountInfoString(). The function parameter values can accept values from the corresponding ENUM_ACCOUNT_INFO enumerations.

There are several types of accounts that can be opened on a trade server. The type of account on which an MQL5 program is running can be found out using the ENUM_ACCOUNT_TRADE_MODE enumeration.

ENUM_ACCOUNT_TRADE_MODE

Identifier	Description
ACCOUNT_TRADE_MODE_DEMO	Demo account

ACCOUNT_TRADE_MODE_REAL	Real account

In case equity is not enough for maintaining open positions, the Stop Out situation, i.e. forced closing occurs. The minimum margin level at which Stop Out occurs can be set in percentage or in monetary terms. To find out the mode set for the account use the ENUM_ACCOUNT_STOPOUT_MODE enumeration.

ENUM_ACCOUNT_STOPOUT_MODE

ACCOUNT_STOPOUT_MODE_MONEY	Account stop out mode in money

ENUM_ACCOUNT_MARGIN_MODE

Identifier	Description

ACCOUNT_MARGIN_MODE_EXCHANGE	Used for the exchange markets. Margin is calculated based on the discounts specified in symbol settings. Discounts are set by the broker, but not less than the values set by the exchange.
ACCOUNT_MARGIN_MODE_RETAIL_HEDGING	Used for the exchange markets where individual positions are possible (hedging, multiple positions can exist for one symbol). The margin is calculated based on the symbol type (SYMBOL_TRADE_CALC_MODE) taking into account the hedged margin (SYMBOL_MARGIN_HEDGED).

i am aware of those but they are predefined variable with predefined value. and you can only read them, can't write to it

what i need is the ability to store a value that is tied to the account

Why dont you simply put such vars in a struct and save that to a file?

For the OP question this would be sufficient. But there could be situations when a client trades from different PCs and wants to have a centralized storage of some data (did you hear about synchronization between devices, which is very common today?). In case of MetaTrader the answer is no. The only shared storage is trading history.

Not sure it's a responsibility of Metaquotes to provide such storage. There is a lot of techniques already available and that can be used from MT4/MT5.

Yes. That is called a workaround, no native support in MT4/MT5. Of course, they can design their products as they want. And this feature is not primary.
