"stopped because of Stop Out" is wirtten in the journal.

Seems that you get a Margin Call...

Why would I get a margin call if I was making a profit?

well i suggest you start reading what a margin call is and how the margin used and free margin is calculated... note that you would require some free margin to open a position...

The two are independent. Some free margin to open a position is only half the problem. As the market move against the position(s), free margin drops. Once it reaches zero - margin call. If you max out your margin and the market drops by one point, margin call.

You must prevent margin call by reducing lot size for the last open order.

    perLotPerPoint  = PointValuePerLot();
    total.risk      = 0;
    oo.lots         = 0;                    // _> multiple open.
    for(int pos = OrdersTotal()-1; pos >= 0 ; pos--) if (
        OrderSelect(pos, SELECT_BY_POS)             // Only my orders w/
    &&  OrderMagicNumber() == Magic.Number          // my magic number
    &&  OrderSymbol()      == Symbol() ){           // and period and symbol
        oo.lots += OrderLots();
        perPoint        = OrderLots()*perLotPerPoint,
        eRisk           = DIR*(OrderOpenPrice()-OrderStopLoss())*perPoint;
        if (eRisk > 0)  total.risk += eRisk;    // Total balance reduction.
...
double LotSize(double risk){
    ... compute size ...
    double  minLot  = MarketInfo(Symbol(), MODE_MINLOT),
            LotStep = MarketInfo(Symbol(), MODE_LOTSTEP),
            perLotPerPoint  = PointValuePerLot(),
            maxLossPerLot   = risk * perLotPerPoint,
            size = at.risk / maxLossPerLot; // Must still round to LotStep.
    /*---- Compute lot size based on account balance and MM mode*/}
    /* The broker doesn't care about the at.risk/account balance. They care
     * about margin. Margin used=lots used*marginPerLot and that must be less
     * than free margin available. Using the lesser of size vs
     * AccountFreeMargin / MODE_MARGINREQUIRED should have been sufficient, but
     * the tester was generating error 134 even when marginFree should have been
     * OK. So I also use AccountFreeMarginCheck < 0 which agrees with the
     * tester. Reported at https://www.mql5.com/en/forum/128506
     *
     * Second problem, after opening the new order, if free margin then drops to
     * zero we get a margin call. In the tester, the test stops with: "EA:
     * stopped because of Stop Out" So I make sure that the free margin
     * after is larger then the equity risk so I never get a margin call. */
