hello guys

I have a question here... how do I change the following;

extern double MaxLot = 1.50;
double max_lot = GetMaxLot(OP_BUY, OP_SELL);
if (max_lot >= MaxLot) lot = CalcHedgeLot(order_type);
(order_type)]: ", lot);

if (lot == -1) return (lot);

lot = NormalizeDouble(lot, LotPrec);
if (lot > MaxLot) lot = MaxLot;
if (lot < MinLot) lot = MinLot;

return (lot);

}

the above check for OP_BUY AND OP_SELL

question: how do I change it to any OP_BUY OR any OP_SELL

appreciate

Its all hidden within the function GetMaxLot( int, int ).

Please post the detail of that function.
If everyone believes it, it will work.

Would have to agree with EAprogrammer ... further details on GetMaxLot
required.

is this the one?

double GetMaxLot(int type1, int type2)
{
double max_lot = 0.0;

int cnt = OrdersTotal();
for (int i=0; i < cnt; i++)
{
if (!OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) continue;
if (OrderSymbol() != Symbol()) continue;
if (OrderMagicNumber() != Magic) continue;
if (OrderType() != type1 && OrderType() != type2) continue;
if (max_lot == 0 || OrderLots() >= max_lot)
{
max_lot = OrderLots();
}
}

return (max_lot);
}

Inserted Code
double GetMaxLot(int type1, int type2)
{
  double max_lot = 0.0;
  
  int cnt = OrdersTotal();
  for (int i=0; i < cnt; i++) 
[color="Blue"]// loop will cycle thru each order in the trading pool (open/pending orders)[/color]
  {
    if (!OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) continue;
[color="Blue"]// above line of code returns Order# 'i' in the queue[/color]
    if (OrderSymbol() != Symbol()) continue;
[color="#0000ff"]// this order must be same currency pair as currently open chart, otherwise skip rest of processing[/color]
    if (OrderMagicNumber() != Magic) continue;
[color="#0000ff"]// order must also have same magic# as that specified in variable 'Magic', otherwise skip rest of processing[/color]
    if (OrderType() != type1 && OrderType() != type2) continue;
[color="#0000ff"]// order must also be either same type as either type1 OR type2, otherwise skip rest of processing[/color]
    if (max_lot == 0 || OrderLots() >= max_lot)
[color="#0000ff"]// sets 'max_lot' equal to number of lots in current order, if the latter exceeds the current value in 'max_lot' 
// (note: IMHO the 'max_lot == 0' test is redundant)[/color]
    {
      max_lot = OrderLots();
    }
  }
  
  return (max_lot);
[color="#0000ff"]// hence function will return the highest #lots of any order in the queue that meets all above criteria[/color]

Forexarch, hope this helps.
