Topic: Modification of the function Max_OpenPos = 1; // Max open positions (c

The main steps are:

Modify Position Counting: Change the function that counts positions to consider all open positions in the account, regardless of magic number or symbol.
Update Position Opening Check: Ensure that before opening a new position, the EA checks if there is already at least one open position across the entire account.
Maintain Compatibility with Other Protections: Ensure that other existing protections in the EA continue to work as expected.

Modify the Global Position Counting Function

int CountPositions(void)
{
    return PositionsTotal();
}

Update the SetPosStats Function to Reflect Global Counting


void SetPosStats(void)
{
    posStatCount  = CountPositions();
    posStatLots   = 0;
    posStatProfit = 0;

    for(int i = PositionsTotal() - 1; i >= 0; i -= 1)
    {
        const ulong ticket = PositionGetTicket(i);
        if(ticket == 0 || !PositionSelectByTicket(ticket))
            continue;

        posStatLots   += PositionGetDouble(POSITION_VOLUME);
        posStatProfit += PositionGetDouble(POSITION_PROFIT) +
                         PositionGetDouble(POSITION_SWAP);
    }
}

Update the Check in OpenPosition

void OpenPosition(Signal &signal)
{
    entryProtectionMessage = "";
    const int spread = (int)((Ask() - Bid()) / _Point);
    
    // Verificações de proteção de entrada
    if (Max_OpenPos > sigma && posStatCount >= Max_OpenPos)
        entryProtectionMessage += StringFormat("Protection: Max open positions: %d, current: %d\n",
                                               Max_OpenPos, posStatCount);
    if (Max_OpenLots > sigma && posStatLots > Max_OpenLots - sigma)
        entryProtectionMessage += StringFormat("Protection: Max open lots: %.2f, current: %.2f\n",
                                               Max_OpenLots, posStatLots);
    if (Max_Spread > sigma && spread > Max_Spread)
        entryProtectionMessage += StringFormat("Protection: Max spread: %d, current: %d\n",
                                               Max_Spread, spread);
    if (MaxDailyLoss > sigma && dailyLoss >= MaxDailyLoss)
        entryProtectionMessage += StringFormat("Protection: Max daily loss: %d, current: %.2f\n",
                                               MaxDailyLoss, dailyLoss);
    if (Max_Daily_DD > sigma && dailyDrawdown >= Max_Daily_DD)
        entryProtectionMessage += StringFormat("Protection: Max daily drawdown: %.2f%%, current: %.2f%%\n",
                                               Max_Daily_DD, dailyDrawdown);
    if (GlobalVariableGet(accEntrySuspendGlobalVarName) > sigma)
        entryProtectionMessage += StringFormat("New entries are suspended until the Daily reset hour: %d",
                                               Daily_Reset);

    const int newsIndex = NewsFilterActive();
    if (newsIndex > -1)
    {
        const NewsRecord newsRecord = newsRecords[newsIndex];
        const datetime timeShift = (datetime) MathRound((TimeLocal() - TimeGMT()) / 3600.0) * 3600;
        const string priority = newsRecord.priority == "high" ? "[high]" : "[med]";
        entryProtectionMessage += StringFormat("News filter: %s %s %s %s\n",
                                               priority,
                                               TimeToString(newsRecord.time + timeShift,
                                                            TIME_DATE | TIME_MINUTES),
                                               newsRecord.currency,
                                               newsRecord.title);
    }

    if (entryProtectionMessage != "")
    {
        entryProtectionMessage = TimeToString(TimeCurrent()) + " " +
                                 "An entry order was canceled:\n" +
                                 entryProtectionMessage;
        return;
    }

    // Verifica a direção de negociação antes de executar a ordem
    const int command = OrderDirectionToCommand(signal.Direction);
    
    // Verifica se a direção da negociação é permitida
    if ((tradeDirection == SomenteCompra && command != OP_BUY) ||
        (tradeDirection == SomenteVenda && command != OP_SELL))
    {
        // Não prossegue se a direção da negociação não corresponde
        return;
    }

    const double stopLoss = GetStopLossPrice(command, signal.StopLossPips);
    const double takeProfit = GetTakeProfitPrice(command, signal.TakeProfitPips);
    const double posLots = Entry_Amount;

    if (ManageOrderSend(command, posLots, stopLoss, takeProfit, 0, signal.MagicNumber))
    {
        posStatCount += 1;
        posStatLots += posLots;
    }
}


Update the OnTick Function to Reflect the Changes

void OnTick(void)
{
    if(!MQLInfoInteger(MQL_TESTER))
    {
        UpdateAccountProtection();
        CheckAccountProtection();

        const datetime time = TimeCurrent();
        if(time > lastStatsUpdate + 3)
        {
            lastStatsUpdate = time;
            SetPosStats(); // Agora considera todas as posições
            UpdateStats();
        }

        if(time > lastNewsUpdate + 6*60*60 || !isNewsFeedOk)
        {
            lastNewsUpdate = time;
            LoadNews();
        }
    }

    if(IsForceSessionClose())
    {
        CloseAllPositions();
        return;
    }

    const datetime time = Time(0);
    if(time > barTime)
    {
        barTime = time;
        OnBar();
    }
}
