Something goes wrong. The demo account was wiped out completely.

Here is a small part from the expert log, with hundreds of those "invalid price for OrderClose function" :

GBPJPY at 209.23 sl: 212.23 tp: 208.23 ok

this is the part in the ea for the OrderClose,
I do not see what is wrong in it, maybe someone can help?

//---------------------
int l_ord_total_72 = OrdersTotal();
for (int l_pos_76 = 0; l_pos_76 < l_ord_total_72; l_pos_76++) {
if (OrderSelect(l_pos_76, SELECT_BY_POS, MODE_TRADES)) {
if (OrderSymbol() == Symbol()) {
l_cmd_80 = OrderType();
if (l_cmd_80 == OP_BUY) {
l_count_56++;
if (l_isar_48 > Close[0]) OrderClose(OrderTicket(), OrderLots(), Bid, 3, Violet);
}
if (l_cmd_80 == OP_SELL) {
l_count_60++;
if (l_isar_48 < Close[0]) OrderClose(OrderTicket(), OrderLots(), Ask, 3, Violet);
}
}
}
}

Compiling does not give an error.
