Can anyone support(suggest) me to solve the strange issue?

I would like to close my order partially 50% of lot size when it is in +20 pips.

so when order is >20 pips i tried following code:

int orderstotal = OrdersTotal();
int orders = 0;
int ordticket[30][2];
double lots = 0;
for (int i = 0; i < orderstotal; i++)
{
OrderSelect(i, SELECT_BY_POS, MODE_TRADES);
if (OrderType() != OP_BUY || OrderSymbol() != Symbol() || OrderMagicNumber() != MagicNumber)
{
    continue;
}
ordticket[orders][0] = OrderOpenTime();
ordticket[orders][1] = OrderTicket();
orders++;
}
if (orders > 1)
{
ArrayResize(ordticket,orders);
ArraySort(ordticket);
}
for (i = 0; i < orders; i++)
{
    if (OrderSelect(ordticket[i][1], SELECT_BY_TICKET) == true)
    {
        lots = OrderLots()*Lots/100;
        lots=NormalizeDouble(lots, NDigits);
         if (lots < MarketInfo(Symbol(), MODE_MINLOT))    // make sure lot is not smaller than allowed value
            lots = MarketInfo(Symbol(), MODE_MINLOT);
        bool ret = OrderClose(OrderTicket(), lots, OrderClosePrice(), 4, blue);
        if (ret == false)
        Print("OrderClose() error - ", ErrorDescription(GetLastError()));

    }
}
return;

but due to high impact news time like ECB,FOMC minutes EA not closing the partial order when +20 pips. what could be the issue?

is there any idea to rewrite my code to close the order till it executes?

Your help is appreciated. Thanks
