OrderClose generating more orders

[Marcos Gomes Artischeff]

Hi people, how are you? I am trying to code an EA for MQL4 that closes an order if it is below or above the entry in some candle number, but when using OrderClose it generates more order?! Weird, orderclose sending more orders?

On the next tick your condition is still true, count is zero, and you open another. Act on a change of signal.

I don't know if correct, but the problem can be the loop for, right?

  for(int ci = OrdersTotal();ci >= 0;ci--)
  {
  if(OrderSelect(ci,SELECT_BY_POS,MODE_TRADES))
  {

1. That loop selects all orders. You don't show what the loop is doing.

   We can't see your broken code.

2. That loop has nothing to do with what I guessed is your problem.

William, hello, how are you? Another thing I didn't understand is: the -1 in PositionsTotal(), sometimes, people uses -1 instead of purely PositionsTotal(), why?

If there are n items, their positions are [0 … n-1].

MQL5 has  PositionsTotal().

MQL4 doesn't as far as I know.

I forgot this section is for MQL4 only, sorry.
