Hi Mladen,

Here is what the loop says for those pending orders where Multi_Indic_00 is an oscillator and Up_Prime_00 is a define level.

//+--------------------------------------------------------------------+

//---- Check And Close If Order Type is Limit And Trend has Changed.

if(OrderType()==OP_BUYLIMIT)

if(( Multi_Indic_00 ) <= (Up_Prime_00 ))

{

_OrderDelete=OrderDelete(OrderTicket());

}

if(OrderType()==OP_SELLLIMIT)

if(( Multi_Indic_00 ) >= ( Down_Prime_00 ))

{

_OrderDelete=OrderDelete(OrderTicket());

}

//+--------------------------------------------------------------------+

Well nothing special....

Happy trading.

Sincerely.

What I would like to see is the for() loop statement. If you are having a for statement like this :

for (int i = 0; i < OrdersTotal(); i++)

then some orders will be missed if in the mean time some orders has been closed or deleted. On the other hand, if the for() loop goes like this :

for (int i = OrdersTotal()-1; i >= 0; i--)

then it will process all the orders

 

Mladen ,

Oh I see:

Here is it for the close process:

"

for(int i=0;i<OrdersTotal();i++)

{

if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false) break;

if(OrderMagicNumber()!=MAGIC || OrderSymbol()!=Symbol()) continue;

"

Change the loop to

for(int i=OrdersTotal()-1;i>=0;i--)

and it should be OK

 

Mladen,

Bingo!

It now does exactly what I needed.

Thanks very much for your great help.

Hi Mladen, thanks for every thing, working good there now...

now i'm stuck with an indicator created that is not reloading so everytime a candle close i have to reload the indicator, can you help me fix this?? here is part of the code (is a trend indicator based on gaps simple idea, thank you:

Hi Mladen, thank you but writing the code this way, there are missing signals, please have a look i made a picture comparing them on daily chart USDJPY:

What can this be?

daniel1983

In your code you used future values (these :

High-Close

Low-Close

I used Close - which is a normal previous value. Change it to but then it will repaint

 

Dear mrtools and mladen

Can anybody assist? Tom Demark Moving Average is a key indicator within my strategy, however, an alarm would be very useful for when a new shelf is indicated; I would be very grateful if an alarm could coded into the indicator. Looking forward to your kind assistance.

Many thanks
