As you well know, Both 'Bars' and 'iBars' are key words in MT (iBars() being a builtin function), and should not be used in the fastion indicated, it will cause an error as you can not set the key word 'Bars' to another value. and the use of iBars as a veriable name would be confusing, as well. I understand were your coming from but someone not well versed in the MQ language will be misleaded with your choice of varible naming here, especially if they carry them over in their code.

Hello,

Thanks for the reply. So how is it really done ?

What I need to do is to check if the bar has ended on a different time frame.
For exemple, with the chart on 30 MIN I want to check if we have a new bar on the 240 MIN

Thanks!

Well I'm back for help again lol but there's no suprise there

could someone please post the code for opening a position 1min after a new bar is open.
I have been trying to do this but don't know where to start. I have been looking at it for the cat of nine tails experiment it migt be a waste of energy but we have to try these things. unless someone else have done this before if please let be know you results.
T1=1 min
T2=2min etc

if (minute() =T1>open && Price > open = Long);

I'm rubbish at this coding lark

Something like this ?

PHP Code:


			
if(TimeCurrent() == Time[0] + T1 * 60)

{



}

How can I let one indicator to show another indicator's Multi Timeframe
situation and give us alert?

For example:

A indicator

Only one timeframe situation shown)
functionA (it's a complex program)

B Indicator

Show A indicator's different timeframe situation)
functionA M5 situation
functionA M15 situation
functionA M30 situation
functionA H1 situation
functionA H4 situation
functionA D1 situation
......

Best regards

You could try looking in the MetaEditor help file at the iCustom function. That should help you accomplish what you're after.

Good Luck

You must give more room for the condition because ticks don't come each second. If there's no tick at bar opentime + Xseconds, the condition will be false.

You are absolutely right. But it was just to give some idea. I think the problem for Beno is to avoid the TradeContextBuzy, opening several positions at the open of a bar.
I don't think that to use a timer is a good idea. For this kind of problem, or Requote etc, usually I set a flag at the open of the bar, and this flag is reset when the order is opened. Until the position is opened, a try is done every tick. Something like this:

PHP Code:


			
if(Time[0] > BarTime)

{

   BarTime = Time[0];

   if(....) OpenLong = true;

}

if(OpenLong) OpenLong = OrderSend(.....) < 0;

I use the same kind of technique to close many positions and it works very well :

PHP Code:


			
.....

   if(CloseAllLongs) CloseAll(OP_BUY);      

   if(CloseAllShorts) CloseAll(OP_SELL);

}

   

void CloseAll(int Type)

{

   int cnt = 0;

   for(int i = OrdersTotal(); i >= 0; i --)

   {

      if(!OrderSelect(i, SELECT_BY_POS)) continue;

      if(OrderSymbol() != Symbol()) continue;

      if(OrderMagicNumber() != Magic) continue;

      if(OrderType() != Type) continue;

      cnt ++;

      OrderClose(OrderTicket(), OrderLots(), OrderClosePrice(), Slippage, White);

   }

   if(Type == OP_BUY) CloseAllLongs = (cnt > 0);

   if(Type == OP_SELL) CloseAllShorts = (cnt > 0);

}
